A new scientific review published in the journal Frontiers in Psychiatry is bringing renewed attention to the potential of psychedelic therapy as a breakthrough treatment for addiction. The analysis reveals that psychedelic-assisted therapy may significantly reduce problematic alcohol and tobacco use—two of the most common and difficult substance dependencies worldwide.
The review analyzed dozens of studies and clinical trials involving compounds such as psilocybin, LSD, and ayahuasca. Across a range of settings, participants undergoing psychedelic-assisted therapy showed measurable decreases in alcohol and nicotine consumption. These outcomes were often sustained over months, and in some cases, even years.
One of the most compelling findings came from studies using psilocybin to help individuals quit smoking. In these trials, abstinence rates reached as high as 80 percent six months after treatment—far surpassing the success rates of traditional nicotine replacement therapies and counseling.
In the case of alcohol use disorder, psychedelics helped individuals reduce their consumption, experience fewer cravings, and gain psychological insight into the root causes of their addiction. Many participants described the experience as emotionally transformative, reporting feelings of clarity, spiritual awakening, or renewed purpose following treatment.
Researchers believe the efficacy of psychedelic therapy stems from how these substances interact with serotonin receptors in the brain, disrupting habitual behavior patterns and enabling deep emotional processing. When paired with professional therapeutic support, these experiences can help users break destructive cycles and commit to meaningful life changes.
The authors caution that these treatments are not a one-size-fits-all solution and must be conducted under medical supervision in a safe and supportive environment. However, the evidence continues to build in favor of psychedelics as legitimate therapeutic tools, especially in cases where conventional treatments have failed.
As public and scientific interest in psychedelics continues to rise, this review strengthens the case for further investment in research and policy reform. With mental health and addiction crises on the rise, the therapeutic use of psychedelics could be a powerful addition to the modern healing toolkit.
