Does Cannabis Boost Creativity?

New scientific studies suggest that getting high on marijuana can genuinely make you more creative.


For many years, numerous highly-acclaimed artists, scientists, writers, musicians, and creative people of all sorts have claimed that marijuana holds enormous potential to enhance creativity and inspire the imagination. 

Now, new scientific studies are beginning to confirm these claims, and researchers are starting to understand the psychological mechanisms behind how cannabis can improve the creative process.

There’s a common myth, perpetuated by the mainstream media, that people often mistakenly think that they’re brilliant and creative while under the influence of cannabis, only to find that their creations are worthless, or that their insights are meaningless nonsense, upon returning to normal everyday consciousness. 

Let’s dispel this pervasive myth about cannabis right now, by  taking the many anecdotal reports to heart, and looking at what the scientific studies have to say.

From Charles Baudelaire to George Carlin, Shakespeare to Carl Sagan, Louis Armstrong to Paul McCartney, Norman Mailer to Jack Nicholson, the list of accomplished creative people who have claimed a positive influence from their use of cannabis is truly impressive. 

I’ve personally spoken with many accomplished people who made claims about how essential cannabis was for their creative process. For example, when I interviewed the late comedian George Carlin, he told me:

“Pot...changed my thinking. It fostered offbeat thinking...Then it changed my comedy....I became more myself. The comedy became more personal, therefore more political, and therefore more successful...So, suddenly, I also became materially successful. People started buying albums. I had four Gold albums in a row.”

Brian Wilson of the Beach Boys said to Rolling Stone magazine that “marijuana helped” him “write Pet Sounds,” which was ranked by the magazine as the second greatest album of all time. 

Anecdotes about cannabis and creativity abound, but what does the scientific research say?

The Beckley Foundation — a nonprofit organization in England that supports pioneering, multidisciplinary research with cannabis and psychedelic drugs — is presently funding a two-part study on cannabis and creativity, that is being conducted by neuroscience researchers Valerie Curran and Celia Morgan at the University College London. 

Curran and Morgan are currently testing the effects of cannabis use on creativity in 400 subjects, and are then using neuroimaging technology to observe the neurobiological changes in the participants that are associated with creativity, while they are under the influence of cannabis.

Although this study is still in progress, according to Beckley Foundation founder Amanda Feilding, the results so far indicate that cannabis is having a positive influence on the subject’s creative performance.

This new research builds upon a previous study by Celia Morgan, and her colleagues at University College London, that looked at how cannabis intoxication enhanced the effects of “semantic priming,” in which the activation of one word allows people to react more quickly to related words. 

One way that creativity can be described is the ability to find novel connections between different concepts. In psychological terms, the ability to see connections between words is called “semantic priming.” This 2010 study found that subjects linked distantly-related words and concepts significantly quicker when they were high than when they weren’t. 

This “hyper-priming,” as the researchers called it, is evidence that the flow of loose associations that cannabis users report is indeed real, and not an illusion, as some skeptics have claimed.

Additionally, research by Xia Zhang and colleagues at Saskatchewan University has demonstrated that THC — the primary psychoactive component of the cannabis plant--can spur neurogenesis, or new brain cell formation. We now know that the brain is continually rewiring itself, and that it’s always possible to grow new brain cells and learn new skills, which may play a role in creative thinking.

Cannabis has the effect of slightly increasing alpha-wave activity in the brain, and increasing blood flow into the right hemisphere, which is associated with holistic, nonlinear thought. Alpha waves, and right-brain thinking, are generally associated with meditative and relaxed states of consciousness, which are, in turn, often associated with creativity.

Television talk show host Jason Silva summed up how the neurological effects of cannabis effect us psychologically by saying,“Essentially, marijuana can extend the range of our free-associative capacities. It increases the novel ways in which we find connections between ideas, and it also extends the range of ideas that we might somehow relate to one another.”

So the next time you spark up a doobie before watching the sunset, be sure to bring along a pen and notebook to write down any novel ideas or interesting thoughts that you may have. Those fleeting intoxicated insights just may lead to the next Nobel Prize-winning discovery or bestselling novel.

To say that it's always possible to grow new brain cells is misleading. Yes, neurogenesis has been found in the hippocampus and olfactory bulb but if you suffer a damage to other parts of your brain you shouldn't count on it. Marijuana has several active substances, of which some are harmful and others potentially protective. For instance, THC has been associated with hippocampal volume loss (in rats) while cannabidiol may counteract this effect. So it's quite complicated and anyone claiming that "pot is good for the brain" is clearly oversimplifying.

Jasper, grow up. How about discussing like us adults do? The name calling is childish. I do not need a lecture on opening my mind. Pot makes people high and does not offer anything of value. The "value" comes from chemicals in pot. This is why your side does not get anywhere. Your argument is just name calling with generalities.

According to Harvard Provost (and former APA head), Steven Hyman, the idea of "reward system" for dopamine is outdated. Dopamine is involved with salience--importance--like when a rat encodes a memory about under the kitchen table because he finds food there. Thus, any drug (including sugar) that directly or indirectly effects dopamine has the potential to be habit forming. THC attaches to endocannabinoids which aren't fully understood, and there are tons of neurotransmitters of all kinds all over the body. The same substance can do different things in different places, but the holistic understanding of lipophilic (fat-loving) compounds like THC is that they permeate all tissues and have effects more like that of a hormone. i.e. melatonin which helps you prepare for sleep. The idea that the evolution of life on this planet provides for common neurotransmission pathways and the interaction of species, plant and animal, is a given on this planet means that a reductionist view based on neurotransmitters cuts out a great deal of the important information.

sean: "People who [drink alcohol] endanger everyone around them. You drive [drunk] and you put others at risk. That is where I draw the line." Agreed. Driving while intoxicated is foolish. Moral standards demand that alcohol and other potentially reaction-time decreasing drugs be regulated. Unfortunately, cannabis is not properly regulated. Because it is illegal, it is driven by the black market which successful and productive people have little control over. If it were legal and regulated, these risks could be averted.

Other studies open doubts about hippocampal volume loss in the long term in humans: http://informahealthcare.com/doi/abs/10.1080/10550490590899862 That's not to say volume loss is necessarily damaging. One alternate theory would be that the volume loss is indicative of the consolidation of memories, where controlled apoptosis may be part of the destruction of unnecessary pathways.
