Ever since I started researching into technological addictions, I have always speculated that ‘virtual reality addiction’ was something that psychologists would need to keep an eye on. In 1995, I coined the term ‘technological addictions’ in a paper of the same name in the journal Clinical Psychology Forum. In the conclusions of that paper I asserted:
“There is little doubt that activities involving person-machine interactivity are here to stay and that with the introduction of such things [as] virtual reality consoles, the number of potential technological addictions (and addicts) will increase. Although there is little empirical evidence for technological addictions as clinical entities at present, extrapolations from research into fruit machine addiction and the exploratory research into video game addiction suggest that they do (and will) exist”.
Although I wrote the paper over 20 years ago, there is little scientific evidence (as yet) that individuals have become addicted to virtual reality (VR). However, that is probably more to do with the fact that – until very recently – there had been little in the way of affordable VR headsets. (I ought to just add that when I use the term ‘VR addiction’ what I am really talking about is addiction to the applications that can be utilized via VR hardware rather than the VR hardware itself).
VR’s potential in mass commercial markets appears to be finally taking off because of mass-produced affordable hardware such as Oculus Rift, HTC Vive, PlayStation VR and the (ultra-cheap) Google Cardboard (in which a smartphone can be inserted into cardboard VR headset frame). Last year, a report by the marketing and consulting company Tractica claimed that spending on virtual reality hardware could be as much as $21.8 billion (US) by 2020. A more recent report by online and digital market research company Juniper estimated that global sales of VR headsets would rise from 3 million in 2016 to 30 million by 2020. Three markets are likely drive sales, and they all happen to be areas that I research into from an addiction perspective – video gaming, gambling, and sex. I’ve noted in many of my academic papers over the years (particularly my early papers on online gambling addiction and online sex addiction) that when new technological advances occur, the sex and gambling industries always appear to be the first to invest and produce commercial products and services using such technologies, and VR is no different. As an online article in Wareable by Dan Sung on VR sex noted:
“What [VR] headsets offer is immersion; 180-degree (or more), stereoscopic action with you as the star of the show and the adult actors and actresses looking deep and lustfully into your eyes as they tend to your genitalia. It’s small wonder that users have been donning their headsets and earphones in numbers and praying to their god that nobody walks in. Yet gambling and porn are synonymous with addiction, and increasingly, questions are being asked about whether the VR revolution could finally ensnare us humans into virtual worlds”.
I was interviewed by Sung for the same article and I made a number of different observations about VR sex. I commented that in terms of people feeling reinforced, aroused, rewarded, sex is the ultimate in things that are potentially addictive. Sex is one of those activities that is highly reinforcing, it’s highly rewarding and how people feel is probably better than the highs and buzzes from other behaviours. Theoretically, I can see that VR sex addiction would be possible but I don’t think it’s going to be on the same scale as other more traditional addictions. The thing about VR (and VR sex) – and similarly to the internet – is that it’s non-face-to-face, it’s non-threatening, it’s destigmatising, and it’s non-alienating. VR sex could be like that whether it’s with fictitious partners, someone that you’re actually into, or someone that you’ve never met before. Where VR sex is concerned, if you can create a celebrity in a totally fictitious way, that will happen. There may be celebrities out there that will actually endorse this and can make money and commercialise themselves to do that. It can work both ways. Some people might find it creepy while others might see something they can make money from.
In one of my previous blogs I looked at the area of ‘teledildonics’, a VR technology that has been around for over two decades (in fact I was first interviewed on this topic on a 1993 Channel 4 television programme called Checkout ’93). Dan Sung also interviewed Kyle Machulis who runs the Metafetish teledildonics website for his article. He said that in relation to VR sex there is a problem with haptics (i.e., the science of applying tactile sensation and control to interaction with computer applications):
“We’re good on video and audio but haptics is a really, really hard problem…A lot of toys out there right now are horrible and it’s very hard to come up with something quality. So, instead, what the porn industry is aiming for right now is immersion. It may not feel better but they’re so much closer to the action that it may be better, and I think we’re on the cusp of that right now.” First, we need consumer hardware. We need things to be released and available to customers to see if it’s really going to take off or not. But when this happens – late this year, the beginning of next – as soon as the headsets are available, the media is ready and waiting…Of course, there’s straight women, gay men and gay women to develop for too but, for a lot of people, the perfect porn experience is doing something that’s not even physically possible – either through the laws of physics or the laws of land, and that’s something that only VR can solve…Even so, what we saw in teledildonics in gaming is that people used them to begin with but there’s always a lot of fall off with new technologies like this. So, there’s going to be a hardcore set of people who stay with VR porn but it’s hard to say how popular it will be beyond that. We’re all still guessing at the moment. This time next year it will be a completely different story”.
Another area that we will need to monitor is how the gambling industry will harness VR technology. The most obvious application of VR in the gambling world is in the online gambling sector. I can imagine some online gamblers wanting their gambling experiences to be more immersive and for their online gambling sessions to be more akin to gambling offline surrounded by the sights and sounds of an offline gambling venue. There is no technical reason that I know of why people that gamble via their computers, laptops, smartphones or tablets could not wear VR headsets and be playing poker opposite a virtual opponent while still sat on the sofa at home. As Paul Swaddle (CEO of Pocket App) noted in a recent issue of Gambling Insider:
We already know that participation in online gambling is snowballing, so if the entertainment industry can use VR to simulate the experience of being inside a video game, or social media sites can give you the opportunity to not just see your friends’ pictures, but to walk through them, why shouldn’t online casinos be able to do the same? VR may actually be the hook that mobile and online casinos need to draw in more millennials, with the average age of players in mobile casinos currently being 40 [years old], and the average age of mobile gamblers in general being 35 [years old]. Millennials simply aren’t engaging with mobile and online casinos to the same extent as older generations, and I suspect that this is down to younger players being much more used to immersive and sociable gaming, as a result of the cutting-edge developments that are being constantly rolled out in the video gaming industry”.
I agree with Swaddle’s observations as the gambling industry are constantly thinking about the ways to bring in newer players. Today’s modern screenagers love technology and do not appear to have any hang-ups about using wearable technology including Fitbit and the Apple Watch. As Swaddle goes on to say:
“By using VR technology to transport players and their friends to exciting locations for their online gambling experience, such as a famous casino in Las Vegas, or a smoky basement room in 1920s New York, or even to the poker table in the James Bond film Casino Royale, mobile and online casinos may stand a better chance of drawing in younger audiences if they use VR to gamify the casino experience”.
Again, this makes a lot of sense to me and I wouldn’t bet against this happening. Swaddle thinks that such VR gambling experiences will become commonplace in the years to come and that the gambling industry needs to get on the VR bandwagon now.
Perhaps of most psychological concern is the use of VR in video gaming. There is a small minority of players out there who are already experiencing genuine addictions to online gaming. VR takes immersive gaming to the next level, and for those that use games as a method of coping and escape from the problems they have in the real world it’s not hard to see how a minority of individuals will prefer to spend a significant amount of their waking time in VR environments rather than their real life.

The idea for this blog was initiated when I read a snippet in The Fortean Times about a 34-year old man from New York who injected cocaine into his penis and ended up with gangrene and further medical complications. It turns out that this report was based on a letter published in a 1988 issue of the Journal of the American Medical Association by Drs. John Mahler, Samuel Perry and Bruce Sutton (and subsequently reported in a June 1988 issue of the New York Times).
The man in question came in for medical treatment following three days of priapism (i.e., prolonged and painful penile erection) and paraphimosis (i.e., foreskin in uncircumcised males can no longer be pulled over the tip of the penis). To enhance his sexual performance, he had administered cocaine directly into his urethra. After three days, both the priapism and the paraphimosis “spontaneously resolved”. However, the blood that had caused the priapism then leaked to other areas of his body over the next 12 hours (including his feet, hands, genitals, chest, and back). To stop the spread of gangrene, the medics had to partially amputate both of his legs (above the knee), and nine of his fingers. Following this, his penis also developed gangrene and fell off by itself while he was taking a bath. The exact reason for the spread of gangrene was unknown but sexologists (such as Professor John Money) speculated that it may have been because of impure cocaine being used.
When I started to search for medical literature on the topic of injecting drugs directly into male genitalia I was surprised to find quite a few papers on the topic (but unsurprisingly all case study reports given the rarity of such behaviour). One of the earliest I located was one from 1986 in the Journal of Urology by Dr. W. Somers and Dr. F. Lowe. They reported the cases of four heroin abusers with localized gangrene of the genitalia, although only one of these had actually injected heroin directly into his genitalia, in this case his scrotum and perineum (the area between the anus and the scrotum). This latter case developed more severe gangrene and was described as a “more lethal entity” than the gangrene in the other three heroin users’ genitalia.
Later, in a 1999 issue of the American Journal of Forensic Medicine and Pathology, Dr. Charles Winek and his colleagues reported the rare case of a fatality due to a male injecting heroin directly into his penis. The cause of death was determined to be due to heroin and ethanol intoxication. More recently, in a 2005 issue of the Medical Journal of the Iranian Red Crescent, Dr. Z. Ahmadinezhad and his colleagues reported a case of heroin-associated priapism. In their paper, they reported the case of a 32-year old man who was admitted to hospital following pain and swelling after injecting heroin into his penis two weeks earlier. Unfortunately, the person left the hospital following initial consultation and never came back so the outcome of the treatment provided is unknown.
In a 2011 issue of the Internet Journal of Surgery, Dr. I. Malek and colleagues reported the case of a 35-year old long-term intra-venous drug user who injected citric acid laced with heroin into the dorsal vein of his penis. This caused worsening pain and his penis developed gangrene. Over the (non-operative) treatment period, the man’s pain became worse and he had trouble urinating (so he was catheterised). Eventually, the treatment with antibiotics led to a good recovery at three-month follow-up.
Another unusual case was reported by Dr. Francois Brecheteau and his colleagues in a 2013 issue of the Journal of Sexual Medicine. They reported the successful treatment of a 26-year old male drug addict who had injected the opiate drug buprenorphine directly into the dorsal vein of his penis. After unsuccessful antibiotic treatment on its own, they then used a number of simultaneous treatments including heparin, anti-platelet drugs, antibiotics, and hyperbaric oxygen therapy, the man made a successful recovery.
Returning to cocaine rather than opiates, a case report by Dr. V. B. Mouraviev and his colleagues in a 2002 issue of the Scandinavian Journal of Urology and Nephrology reported the case of a 31-year-old Canadian man who had injected cocaine directly into his penis. He turned up at the emergency having endured penile pain for 22 hours following the injection. Twelve hours after injecting the cocaine, the man noticed swelling and bruising starting to appear on the right side of his penis where he had made the injection. As a consequence, his penis developed gangrene (“localized death and decomposition of body tissue, resulting from obstructed circulation or bacterial infection”) most probably from bacterial infection via the injection. He had to undergo reconstructive skin graft surgery and was given antibiotics. In this particular case, the treatment was successful. Other similar reports of medical complications (usually gangrene) following the injection of cocaine into the penis have since appeared in a number of papers including a 2013 paper by Dr. Fahd Khan and colleagues in the Journal of Sexual Medicine.
Cocaine and heroin aren’t the only recreational drugs to have been injected into male genitalia. A paper in a 2014 issue of Urology Case Reports by Dr. Cindy Garcia and her colleagues reported the case of a 45-year-old male intravenous drug user who developed an abscess after he injected amphetamine into his penis. The man chose a penile vein after being unable to find any other suitable peripheral vein. He was treated with intravenous antibiotics and had to have his abscess drained via a penile incision. Within a month he had been all but successfully treated. In their paper (which also included a review of the literature on penile abscesses), they concluded that:
“Penile abscesses are an uncommon condition. There are multiple aetiologies of penile abscesses, including penile injection, penile trauma, and disseminated infection. Penile abscesses might also occur in the absence of an underlying cause. The treatment of penile abscesses should depend on the extent of infection and the cause of the abscess. Most cases of penile abscess necessitate surgical debridement [removal of dead or infected tissue]”.
Similarly, in a 2015 issue of Case Reports in Urology, Dr. Thomas W. Gaither and his colleagues reported two cases of men who had injected metamphetamine into their penis. The first case was a 47-year-old gay man who had a history of “methamphetamine use, prior penile abscesses, urethral foreign body insertions, HIV, hepatitis C, and diabetes mellitus”. He attended the hospital emergency department suffering from severe penile pain and scrotal swelling having injected methamphetamine into the shaft of his penis a few days before. On the same day that he went to the emergency department he was immediately taken into the operating room where an incision was made in his penis, and the abscess was drained of its “purulent foul-smelling fluid” and washed out with saline solution. The second case was a 33-year-old heterosexual male with no previous medical history (apart from a history of depression) turned up at the hospital emergency department with acute penile pain, a day after he had injected methamphetamine directly into his penis. Again, he was immediately taken to the operating room where his penile abscess was drained after an incision. Neither of the cases involved any penile gangrene and both men were also given antibiotics to treat the infected area. In both cases, the authors speculated that the abscesses formed as a result of direct contamination from repeated penile injections.
Finally, Dr. Lucas Prado and his colleagues reported a case study in a 2012 issue of the Journal of Andrology of a 31-year-old man who was admitted to the emergency department after he had injected 10ml of methadone into his penis in an attempt to commit suicide (the first case of penile methadone injection). The man had a 15-year history of drug abuse over the past year and had attempted a drug-related suicide three times. This particular suicide attempt led to acute liver and renal failure as well as erectile dysfunction. Although the man survived, ten months after the suicide attempt, the man still had complete erectile dysfunction.
Although I didn’t do a systematic review of all the literature, it is clear that the injection of recreational drugs directly into male genitalia appears to be relatively rare although all the literature I located was based on those who end up seeking treatment for when things go horribly wrong. There could of course be many hundreds or thousands of people out there that have engaged in such practices but don’t end up in a hospital emergency ward. However, I certainly wouldn’t recommend such a practice to anyone.

Those that know me well often comment that I have a general inability to sit still and that I am a ‘fidget’. (This is not necessarily a bad thing and in fact there are some positives to fidgeting that I outlined in a previous blog on bad behaviours that are sometimes good for you). There is certainly some truth to the observation that I fidget but sometimes the fidgeting is out of my control. Every few weeks my right lower leg appears to take on a life of its own and I will get strange (uncomfortable) sensations (such as tingling, itching, and aching, and occasionally cramp-like feelings) that force me to move my right leg and foot around. It only happens when I am in a resting and relaxing state and usually lasts about 30 minutes (but can occasionally last much longer). On occasions it disrupts my work and sleep but I find that just getting up and moving around is sometimes enough to alleviate the uncomfortable feelings.
A few years ago I Googled my ‘symptoms’ and was surprised to find that I am not the only person who appears to experience such effects and that there is a whole medical literature on what has been termed ‘restless legs syndrome’ although in my case it would be in a singular rather than plural form). I’ve had the condition for about 15 years now and it may be related to some of the medication I take for an unrelated chronic degenerative health condition that I have. According to the Wikipedia entry on restless legs syndrome (RLS):
“The first known medical description of RLS was by Sir Thomas Willis in 1672. Willis emphasized the sleep disruption and limb movements experienced by people with RLS…The term ‘fidgets in the legs’ has also been used as early as the early nineteenth century. Subsequently, other descriptions of RLS were published, including those by Francois Boissier de Sauvages (1763), Magnus Huss (1849), Theodur Wittmaack (1861), George Miller Beard (1880), Georges Gilles de la Tourette (1898), Hermann Oppenheim (1923) and Frederick Gerard Allison (1943). However, it was not until almost three centuries after Willis, in 1945, that Karl-Axel Ekbom (1907–1977) provided a detailed and comprehensive report of this condition in his doctoral thesis, Restless legs: clinical study of hitherto overlooked disease. Ekbom coined the term “restless legs” and continued work on this disorder throughout his career. He described the essential diagnostic symptoms, differential diagnosis from other conditions, prevalence, relation to anemia, and common occurrence during pregnancy. Ekbom’s work was largely ignored until it was rediscovered by Arthur S. Walters and Wayne A. Hening in the 1980s. Subsequent landmark publications include 1995 and 2003 papers, which revised and updated the diagnostic criteria”.
As well as being referred to as RLS, it is sometimes referred to as Willis-Ekbom Disease or Willis-Ekbom Syndrome. Since being ‘rediscovered’ in the 1980s, there have been a lot of scientific papers published on the phenomenon although many of these are medical case studies (I don’t think my own experiences are extreme enough or strong enough to appear in any medical textbook. The Wikipedia entry on RLS provides a good summary of what is known medically and empirically:
“Restless legs syndrome (RLS) is a disorder that causes a strong urge to move one’s legs. There is often an unpleasant feeling in the legs that improves somewhat with moving them. Occasionally the arms may also be affected. The feelings generally happen when at rest and therefore can make it hard to sleep. Due to the disturbance in sleep, people with RLS may have daytime sleepiness, low energy, irritability, and a depressed mood. Additionally, many have limb twitching during sleep. Risk factors for RLS include low iron levels, kidney failure, Parkinson’s disease, diabetes, rheumatoid arthritis, and pregnancy. A number of medications may also trigger the disorder including antidepressants, antipsychotics, antihistamines, and calcium channel blockers. There are two main types. One is early onset RLS which starts before age 45 [years], runs in families and worsens over time. The other is late onset RLS which begins after age 45 [years], starts suddenly, and does not worsen. Diagnosis is generally based on a person’s symptoms after ruling out other potential causes… Females are more commonly affected than males and it becomes more common with age…Some doctors express the view that the incidence of restless leg syndrome is exaggerated by manufacturers of drugs used to treat it. Others believe it is an under-recognized and undertreated disorder…An association has been observed between attention deficit hyperactivity disorder (ADHD) and RLS or periodic limb movement disorder. Both conditions appear to have links to dysfunctions related to the neurotransmitter dopamine, and common medications for both conditions among other systems, affect dopamine levels in the brain”.
According to a review by Dr. Richard Allen and Dr. Christopher Earley in the Journal of Clinical Neurophysiology, RLS affects 2.5-15% of the US population. In another review on sleep disorder in the journal American Family Physician, Dr. Kannan Ramar and Dr. Eric Olson reported that RLS is typically characterized by four essential features: These are:
“(1) the intense urge to move the legs, usually accompanied or caused by uncomfortable sensations (e.g., “creepy crawly,” aching) in the legs; (2) symptoms that begin or worsen during periods of rest or inactivity; (3) symptoms that are partially or totally relieved by movements such as walking or stretching; and (4) symptoms that are worse or only occur in the evening or at night”.
Various online articles and papers report a variety of potential treatments based on the notion that RLS might be caused by a dopamine imbalance in the body. Some medics advise a regular sleep routine (such as that advised for those with insomnia), and cutting out the drinking of alcohol and the smoking of cigarettes. Pharmacological treatments include the use of drugs that are also used in the treatment of Parkinson’s disease such as L-DOPA and pramipexole, and the use of magnesium sulphate therapy (as reported in a 2006 paper in the Journal of Clinical Sleep Medicine – magnesium is known to be a natural muscle relaxant). In a 2011 issue of the journal Sleep Medicine, In an online article about RLS, Dr Michael Platt, author of the 2014 book Adrenalin Dominance, claims that RLS sufferers can be treated using a progesterone cream:
“Excess adrenalin during the night can cause restless leg syndrome. People often have associated symptoms also resulting from elevated adrenalin, such as teeth grinding, the need to urinate, and tossing and turning, and they often awaken in the morning with low back pain. Characteristically, RLS patients have an excess of adrenaline, may toss and turn all night, be quick to anger, might be workaholics, will usually have fibromyalgia (aches and pains – low back, side of the hips, and grind their teeth), they might drink too much, and will be hypoglycemic (sleepy between 3-4 p.m. or when in a car), and so on. There is an associated over-production of insulin and an under-production of progesterone…[By using a progesterone cream] I have had 100% success with eliminating RLS by getting hormones into balance, often within the first week. Patients feel more relaxed, they can sleep at night, rage disappears, and they can focus more easily”.
Dr. Luis Marin and his colleagues reported a different treatment for RLS altogether. They reported the case of a 41-year-old male RLS sufferer who after being on medication for RLS discovered his own solution – having sex. Following sex, the man reported that all RLS symptoms would disappear. Marin and colleagues speculated that the release of dopamine following orgasm might alleviate RLS symptoms. This appears to be a reasonable speculation given the findings of research published in the Journal of Neuroscience by Dr. Gert Holstege and his colleagues who examined brain activation at the point of ejaculation. In their paper they reported the similarity between ejaculation and using heroin in terms of brain activation:
“We used positron emission tomography to measure increases in regional cerebral blood flow during ejaculation compared with sexual stimulation in heterosexual male volunteers. Manual penile stimulation was performed by the volunteer’s female partner. Primary activation was found in the mesodiencephalic transition zone, including the ventral tegmental area, which is involved in a wide variety of rewarding behaviors. Parallels are drawn between ejaculation and heroin rush”.
It could well be that the increase in dopamine following ejaculation acts in a similar way to the medications that are given to RLS sufferers. Of all the treatments for RLS that I have read about, I think I know which one I would prefer!

In a previous blog I examined whether celebrities are more prone to addictions. In that article I argued that many high profile celebrities have the financial means to afford a drug habit like cocaine or heroin. For many in the entertainment business such as being the lead singer in a famous rock band, taking drugs may also be viewed as one of the defining behaviours of the stereotypical ‘rock ‘n’ roll’ lifestyle. In short, it’s almost expected. There is also another way of looking at the relationship between celebrities and drugs and this is in relation to creativity, particularly as to whether the use of drugs can inspire creative writing or music. For instance, did drugs like cannabis and LSD help The Beatles create some of the best music ever such as Revolver? Did the Beach Boys’ Brian Wilson’s use of drugs play a major role in why the album Pet Sounds is often voted the best album of all time? Did the use of opium by Edgar Allen Poe create great fiction? Did William S. Burroughs’ use of heroin enhance his novel writing?
To investigate the question of whether drug use enhances creativity, I and my research colleagues Fruzsina Iszáj and Zsolt Demetrovics have just published a review paper in the International Journal of Mental Health and Addiction examining this issue. We carried out a systematic review of the psychological literature and reviewed any study that provided empirical data on the relationship between psychoactive substance use and creativity/artistic creative process that had been published in English in peer-reviewed journals or scientific books. Following a rigorous filtering process, we were surprised to find only 19 studies that had empirically examined the relationship between drug use and creativity (14 empirical studies and five case studies).
Six of the 19 studies (four empirical papers and two case reports) were published during the 1960s and 1970s. However, following the peak of psychedelia, only three papers (all of them empirical) were published in the following 20 years. Since 2003, a further 10 studies were published (seven empirical papers and three case studies). The majority of the studies (58%) were published in the USA. This dominance is especially true for the early studies in which six of the seven empirical papers and both case studies that were published before mid-1990s were written by US researchers. However, over the past 14 years, this has changed. The seven empirical papers published post-2000 were shared between six different countries (USA, UK, Italy, Wales, Hungary, Austria), and the three case studies came from three countries (USA, UK, Germany).
Seven empirical papers and two case studies dealt with the relationship between various psychoactive substances and artistic creation/creativity. Among the studies that examined a specific substance, six (three empirical papers and three case studies) focused on the effects of either LSD or psilocybin. One empirical study focused on cannabis, and one concerned ayahuasca.
With the exception of one study where the sample focused on adolescents, all the studies comprised adults. More non-clinical samples (15 studies, including case studies) were found than clinical ones (four studies). Three different methodological approaches were identified. Among the empirical studies, seven used questionnaires comprising psychological assessment measures such as the Torrance Test of Creative Thinking (TTCT).
According to the types of psychoactive substance effect on creativity, we identified three groups. These were studies that examined the effect of psychedelic substances (n=5), the effect of cannabis (n=1), and those that did not make a distinction between substances used because of the diverse substances used by participants in the samples (n=7). In one study, the substances studied were not explicitly identified.
The most notable observation of our review was that the findings of these studies show only limited convergence. The main reason for this is likely to be found in the extreme heterogeneity concerning the objectives, methodology, samples, applied measures, and psychoactive substances examined among the small number of studies. Consequently, it is hard to draw a clear conclusion about the effect of psychoactive substance use on creativity based on the reviewed material.
Despite the limited agreement, most of the studies confirmed some sort of association between creativity and psychoactive substance use, but the nature of this relationship was not clearly established. The frequently discussed view that the use of psychoactive substances leads to enhanced creativity was by no means confirmed. What the review of relevant studies suggests is that: (i) substance use is more characteristic in those with higher creativity than in other populations, and (ii) it is probable that this association is based on the inter-relationship of these two phenomena. At the same time, it is probable that there is no evidence of a direct contribution of psychoactive substances to enhanced creativity of artists.
It is more likely that substances act indirectly by enhancing experiences and sensitivity, and loosening conscious processes that might have an influence on the creative process. This means the artist will not be more creative but the quality of the artistic product will be altered due to substance use. On the other hand, it appears that psychoactive substances may have another role concerning artists, namely that they stabilize and/or compensate a more unstable functioning.
Beyond the artistic product, we also noted that (iii) specific functions associated with creativity appear to be modified and enhanced in the case of ordinary individuals due to psychoactive substance use. However, it needs to be emphasized that these studies examined specific functions while creativity is a complex process. In light of these studies, it is clear that psychoactive substances might contribute to a change of aesthetic experience, or enhanced creative problem solving. One study (a case study of the cartoonist Robert Crumb) showed that LSD changed his cartoon illustrating style. Similarly, a case study of Brian Wilson argued that the modification of musical style was connected to substance use. However, these changes in themselves will not result in creative production (although they may contribute to the change of production style or to the modification of certain aspects of pieces of arts). What was also shown is that (iv) in certain cases, substances may strengthen already existing personality traits.
In connection with the findings reviewed, one should not overlook that studies focused on two basically different areas of creative processes. Some studies examined the actual effects of a psychoactive substance or substances in a controlled setting, while others examined the association between creativity and chronic substance users. These two facets differ fundamentally. While the former might explain the acute changes in specific functions, the latter may highlight the role of chronic substance use and artistic production.
It should also be noted that the studies we reviewed differed not only regarding their objectives and methodology, but also showed great heterogeneity in quality. Basic methodological problems were identified in many of these studies (small sample sizes, unrepresentative samples, reliance on self-report and/or non-standardized assessment methods, speculative research questions, etc.). Furthermore, the total number of empirical studies was very few. At the same time, the topic is highly relevant both in order to understand the high level of substance use in artists and in order to clarify the validity of the association present in public opinion. However, it is important that future studies put specific emphasis on adequate methodology and clear research questions.
