Cannabis and Music

Cannabis and music refers to the relationship between cannabis use and the creation, performance, and experience of music. Cannabis users widely report that the drug enhances their appreciation and enjoyment of music, and cannabis has been deeply associated with several major musical traditions, including jazz, reggae, psychedelic rock, and hip-hop. Despite the cultural prominence of this association, scientific research on the topic remains limited and produces findings that often complicate or contradict popular assumptions — particularly around creativity and musical performance. ^{[1] [2]}

The most characteristic subjective effect of cannabis intoxication, according to the largest early survey of experienced users, is an auditory one: the perception that sounds become purer, more distinct, and richer in detail. ^[3] Yet controlled neuroimaging studies have found that THC dampens brain response to music in regions associated with reward and emotion, even as users report wanting to listen to music more. ^[4] This tension between subjective report and objective measurement runs through the scientific literature on cannabis and music.

Effects on music listening

The effect of cannabis on the experience of listening to music is the most studied dimension of the cannabis–music relationship, though the literature remains small.

Subjective reports

In Charles Tart's 1971 survey of 150 experienced marijuana users, the ability to hear more subtle changes in sounds was reported as a frequent experience by 95% of respondents, making it the single most characteristic effect of marijuana intoxication across all sensory modalities studied. ^[3] Other commonly reported auditory effects included greater spatial separation between instruments, enhanced auditory imagery, improved comprehension of song lyrics, and synesthesia at higher intoxication levels. The only negative auditory effect — blurring of sounds — was among the rarest in the entire study, occurring almost exclusively at very high intoxication levels. ^[3]

Darakjian et al. (2025) surveyed 104 recreational cannabis users and found that 45% named listening to music as their most common activity while high. Participants reported significantly greater hearing sensitivity (p < 0.001) and state absorption in music (p < 0.001) while high compared to sober. ^[1] Qualitative interviews identified four themes: altered cognitive processes and reinterpretations, auditory perceptual effects ranging from new sensations to sensory overload, emotional openness and sensitivity, and embodiment and immersion sometimes extending to dissociation. ^[1]

Auditory perception experiments

Globus et al. (1978) conducted a double-blind experiment with 42 male participants involving a loudness-matching task. Participants who received cannabis after a training phase adjusted comparison tones louder than the criterion, suggesting that tones are perceived as quieter under the influence — consistent with a subjective expansion of auditory sensitivity. ^[5]

Fachner (2002) used EEG brainmapping to measure brain activity during music listening before and after cannabis consumption in four participants. Music listening after cannabis showed increased alpha power in parietal cortex and significant theta-band changes in temporal regions — areas associated with attention and auditory processing. ^[6] A follow-up by Fachner (2006) replicated these findings in a naturalistic setting, arguing that laboratory environments may introduce bias in drug research. Fachner characterized the cannabis-induced shift as "hyperfocusing" on acoustic space. ^[7] Both studies had very small samples and should be considered exploratory.

Neuroimaging

Freeman et al. (2018) used fMRI to examine brain responses to music in 16 cannabis users across three sessions: cannabis with CBD, cannabis without CBD, and placebo. Cannabis without CBD dampened the brain's response to music in bilateral auditory cortex, right hippocampus and parahippocampal gyrus, right amygdala, and right ventral striatum — regions associated with music-evoked reward and emotion. ^[4]

This presents a paradox: the same participants who showed dampened neural reward responses also reported significantly increased desire to listen to music (p < 0.002) and enhanced sound perception (p < 0.001). ^[4] Cannabis containing CBD did not differ from placebo on any fMRI measures, suggesting CBD offset THC's dampening effects. Functional connectivity between the ventral striatum and auditory cortex was increased by CBD. ^[4]

The disconnect between subjective enhancement and neural dampening remains unresolved. It may reflect a genuine dissociation between conscious experience and the neural signals measured by fMRI, or it may indicate that cannabis alters music perception through mechanisms not captured by reward-region activation — for instance, through the attentional shifts observed in EEG studies. ^[6]

Time perception

Altered time perception is one of the most consistently reported subjective effects of cannabis and is frequently invoked to explain cannabis's appeal to musicians and listeners. The hypothesis, commonly associated with early jazz culture, is that cannabis slows the subjective passage of time, allowing musicians to perceive more detail in each musical moment. ^[2]

Atakan et al. (2012) reviewed all available studies on cannabis and time perception and found that approximately 70% of time estimation studies reported overestimation — users judged a given interval as longer than it actually was, consistent with an accelerated internal clock making external time seem slower. ^[8] However, time production and reproduction findings were inconclusive, and the literature suffered from small sample sizes and inconsistent methods. ^[8]

Sewell et al. (2013) administered intravenous THC at multiple doses to 44 participants. All doses produced time overestimation and underproduction compared to placebo. Infrequent cannabis users showed overestimation of up to approximately 25% and underproduction of up to approximately 15% relative to baseline. ^[9] Frequent users showed no significant changes at any dose, suggesting tolerance develops to this effect. ^[9]

Whether time perception changes actually benefit musical performance has never been empirically tested. The claim remains a cultural belief without scientific support or refutation.

Cannabis and creativity

The belief that cannabis enhances creativity is widespread: over 50% of cannabis users report heightened creativity during intoxication. ^[10] The controlled scientific evidence largely fails to support this belief and, at higher doses, contradicts it.

Divergent and convergent thinking

Kowal et al. (2015) conducted a randomized, double-blind, placebo-controlled study with 54 regular cannabis users. Low-dose THC (5.5 mg) had no measurable impact on divergent or convergent thinking. High-dose THC (22 mg) significantly impaired divergent thinking, while convergent thinking was unaffected at either dose. ^[10]

Schafer et al. (2012) tested 160 cannabis users both sober and intoxicated and found that cannabis increased verbal fluency in individuals low in baseline trait creativity, bringing them to the same level as high-creativity individuals. Cannabis had no effect on those already high in trait creativity, and category fluency was unaffected. ^[11]

Feeling creative versus being creative

Heng et al. (2023) randomly assigned participants to cannabis-use or abstinence conditions and had them complete creativity tasks. Independent raters found no difference in actual creative quality between groups. However, cannabis users rated both their own ideas and others' ideas as more creative — an effect mediated by cannabis-induced joviality. ^[12] The authors concluded that cannabis may positively bias evaluations of creativity without improving creativity itself. ^[12]

This offers a potential explanation for the widespread belief: the drug reliably produces a state in which one's own output feels more creative, even when objective assessment shows no improvement.

Personality and self-selection

LaFrance and Cuttler (2017) found that sober cannabis users self-report higher creativity and score higher on openness to experience — a trait linked to both cannabis use and creative achievement. ^[13] Their analysis suggested that enhanced divergent thinking in sober cannabis users may be driven by pre-existing personality traits rather than pharmacological effects. Creative people may be more likely to use cannabis, rather than cannabis making people more creative. ^[13]

Musical performance and motor skills

Despite the long cultural association between cannabis and musical performance, no published controlled studies specifically measure the effects of cannabis on musical instrument performance, singing, or improvisation. This is one of the most significant gaps in the literature.

Cannabis impairs motor control, fine motor skills, reaction time, and coordination through effects on cortico-striatal networks. ^[14] Ramaekers et al. (2006) found that high-potency THC significantly impaired motor control and executive function in a double-blind, placebo-controlled study, with impairments lasting up to six hours and effect sizes doubling from lower to higher doses. ^[15]

Prashad and Bhatt (2016) reviewed motor dysfunction in cannabis users and identified a critical gap: while studies have examined cannabis's effects on already-learned motor tasks, almost no research has addressed how cannabis affects motor learning — the acquisition of new skills. ^[14] Musical instrument performance involves complex motor sequences with fine temporal coordination, and the cortico-striatal networks implicated in both cannabis's effects and motor learning overlap substantially. ^[14]

The motor impairment literature would predict decreased quality of musical performance under cannabis influence, particularly for tasks requiring fine motor precision. This stands in tension with the widespread belief among musicians that cannabis aids performance. Webster (2001) speculated that cannabis-altered short-term memory might facilitate improvisational thinking by reducing attachment to pre-planned sequences, but acknowledged this was speculation rather than evidence. ^[2] The hypothesis that cannabis aided jazz improvisation — sometimes attributed to pharmacologist James Munch's claim that cannabis allowed musicians to "work in about twice as much music between the first note and the second note" — has never been tested in a controlled setting.

Cultural history

In the early jazz scene of the 1920s through 1940s, cannabis was widely used among musicians known as "vipers." Winick (1959) surveyed 357 jazz musicians and found that 82% had tried marijuana, 54% were occasional users, and 23% were regulars. ^[16] Cannabis-referencing songs were common, including Louis Armstrong's "Muggles" (1928) and Cab Calloway's "Reefer Man" (1932). Singer and Mirhej (2006) contextualized jazz musicians' drug use within ethnic inequality and occupational stress, arguing that cannabis served social-bonding and coping functions within the community. ^[17] Harry Anslinger's Federal Bureau of Narcotics specifically targeted jazz musicians, with the racial dimensions of cannabis prohibition inseparable from the campaign against jazz itself. ^[17]

In reggae, cannabis holds sacramental status within the Rastafari movement, used in reasoning sessions and meditation. Reggae became the primary global vehicle for Rastafari beliefs, with cannabis references permeating the genre — from Bob Marley's Kaya (1978) to Peter Tosh's "Legalize It" (1976). Unlike in jazz, where cannabis was one recreational substance among several, in reggae culture it carries explicit spiritual and political significance.

During the 1960s counterculture, cannabis became a symbol of rebellion alongside other psychoactive substances. Cannabis references proliferated in rock music, from Bob Dylan's "Rainy Day Women #12 & 35" (1966) to Black Sabbath's "Sweet Leaf" (1971). The Woodstock festival (1969) became emblematic of the counterculture's open embrace of cannabis.

In hip-hop, early 1980s music was largely anti-drug amid the crack epidemic. This shifted in the early 1990s with Dr. Dre's The Chronic (1992) and Cypress Hill's Black Sunday (1993), making cannabis central to hip-hop identity. By the 2010s, cannabis evolved from countercultural symbol to commercial enterprise, with artists building cannabis businesses. This commercialization has raised equity concerns, given that communities most harmed by cannabis prohibition have faced barriers to participation in the legal industry.

Analysis

The scientific literature on cannabis and music is strikingly thin relative to the topic's cultural importance. As both Webster (2001) and Fachner (2006) observed, research on cannabis and aesthetic experience has been inhibited by stigma, regulatory obstacles, and the academic perception that drug-related cultural practices are insufficiently serious research topics. ^{[2] [7]}

Several prominent cultural claims remain neither confirmed nor refuted. The claim that cannabis aids improvisation has no controlled evidence for or against it. The claim that cannabis enhances creativity is contradicted by the best available evidence, which shows no objective improvement and, at higher doses, impairment — though these studies measured general divergent thinking, not musical creativity specifically. The claim that cannabis enhances listening is supported by consistent subjective reports across decades but complicated by neuroimaging evidence showing dampened reward-region activation.

The most robust finding may be the most counterintuitive: cannabis does not appear to make people more creative, but it reliably makes them feel more creative. ^[12] Whether this perceptual shift has indirect value — by reducing self-criticism or encouraging openness to unfamiliar ideas — is a question the literature has not yet addressed.

The history of cannabis prohibition has been inseparable from the suppression of Black musical communities, from Anslinger's campaigns against jazz musicians to the disproportionate enforcement of cannabis laws throughout the War on Drugs era. ^[17] The legal framework around cannabis has constrained the agency of the musical communities most associated with it, and the ongoing commercialization of cannabis culture raises questions about who benefits from the normalization that musicians helped bring about.
