Psychedelics Show Promise for Smoking Cessation Research
Scientists are exploring an unexpected ally in the fight against smoking addiction. A new systematic review reveals that classic psychedelics like psilocybin and LSD may help people quit cigarettes, though researchers caution that current evidence remains preliminary.

Breaking New Ground in Addiction Treatment
The research team, led by Dillon Glenn from Wayne State University, analyzed eight studies examining how serotonergic psychedelics affect smoking behaviors. These compounds work by activating 5-HT2A receptors in the brain, creating altered states of consciousness that researchers believe may disrupt addictive patterns.
Traditional smoking cessation methods help only about 20% of people quit long term. This gap has prompted scientists to investigate alternative approaches, including psychedelic therapy.
Mixed Results Across Different Compounds
The review examined six different psychedelics across various studies. Psilocybin emerged as the most frequently studied compound, appearing in seven separate investigations. Researchers found that participants who received psilocybin treatment showed reduced smoking behaviors compared to baseline measurements.
LSD and ayahuasca also demonstrated potential benefits. However, mescaline, peyote, and DMT showed less consistent results across the limited studies available.
Significant Limitations Cloud the Picture
Despite promising initial findings, the research faces serious methodological challenges. All eight studies received ratings indicating serious risk of bias using standardized assessment tools. Most studies lacked control groups, relied on small sample sizes, and failed to account for confounding variables.
The authors emphasize that current evidence cannot establish whether psychedelics directly cause smoking reduction or whether other factors explain the observed changes. Without proper control groups, researchers cannot rule out placebo effects or the influence of therapeutic settings.
Path Forward Requires Rigorous Science
Future studies must address these limitations through randomized controlled trials with larger participant groups. Researchers need to compare psychedelic treatments against established cessation methods and include long term follow up periods to measure sustained abstinence rates.
The field shows promise, but translating these preliminary findings into clinical practice will require substantially more rigorous research.
