A growing body of research is exploring how psychedelic experiences and cannabis use might interact, especially for people who struggle with problematic consumption. A new study from the Journal of Psychoactive Drugs sheds light on this connection by examining how personally meaningful psychedelic experiences may influence cannabis habits months later. While the findings are early, they offer an intriguing look at how altered states of consciousness might support healthier decision making and emotional flexibility.
Cannabis use has increased around the world, with more than 190 million people reporting consumption in 2020. As use rises, so does the number of people facing cannabis use disorder, which affects about one in ten users. Unfortunately, treatment options remain limited. No approved medications exist, and behavioral therapies often help only temporarily. This gap has led researchers to look for new approaches, including whether psychedelic experiences could encourage lasting changes.
Why Psychedelic Experiences And Cannabis Use May Shift After Meaningful Trips
The study focused on adults who had used cannabis and later had a psychedelic experience they considered personally significant. Classic psychedelics like LSD and psilocybin were the most common substances. Although most participants did not take psychedelics with the intention of reducing cannabis use, many still reported noticeable changes afterward.
A total of 152 people completed the online survey, which asked them to recall their cannabis use before and after the psychedelic experience. Many also completed questionnaires measuring psychological flexibility, which reflects a person’s ability to handle difficult emotions and stay connected to their goals.
Across the group, problematic cannabis use decreased significantly. Scores on a standard measure of cannabis use disorder dropped by about 38 percent over six months. Participants used cannabis less often, reported fewer cravings, and spent fewer hours intoxicated each day. The number of people meeting criteria for severe cannabis use disorder dropped from about 23 percent to roughly 9 percent.
At the same time, psychological flexibility increased. Participants reported feeling more capable of navigating challenging emotions and shifting their mindset when needed. These changes appeared as early as one month after the psychedelic experience and continued six months later.
The Role Of Intensity In Psychedelic Experiences And Cannabis Use Changes
Participants who rated their psychedelic experience as more intense tended to report larger reductions in cannabis use and greater improvements in psychological flexibility. Many described their experience as recreational or introspective rather than clinical, yet still found the effects meaningful. This suggests that the quality of the experience, not just the substance itself, may influence these shifts.
However, when researchers used statistical models to identify the strongest predictor of change, baseline cannabis use severity stood out. Those who struggled the most before their psychedelic experience were more likely to reduce their use afterward. Although mystical intensity and psychological flexibility were closely correlated with improvement, they did not independently predict outcomes in the model.
What This Research Means For The Future of Psychedelic-Assisted Care
Because the study was retrospective and relied on memory, it cannot show clear cause and effect. Participants were also recruited through a psychedelic interest community, which may have influenced the results. Without a control group, other life changes cannot be ruled out.
Even with these limitations, the study adds valuable insight into how psychedelic experiences and cannabis use may interact. It also highlights areas for future research, such as prospective studies and the potential value of preparation and integration support.
As interest in psychedelic-assisted therapy grows, understanding how naturalistic psychedelic experiences affect substance use could help shape safer, more structured clinical approaches.
