Pesquisadores of Universidade Johns Hopkins released robust results from a clinical trial in which psilocybin, the active compound in magic mushrooms, significantly outperformed nicotine patches in treating smoking addiction. Seis months after treatment, 52% of participants who received a high dose of psilocybin remained abstinent from cigarettes, compared to just 25% in the group using nicotine patches. Participants were randomly assigned to receive about 30 mg of psilocybin or patches, plus 10 sessions of cognitive behavioral therapy spread over 13 weeks.
Tobacco remains one of the most challenging addictions to give up. Nicotine is as addictive as cocaine and heroin, perhaps even more so. Aproximadamente 70% of adult smokers declare that they want to quit, however less than one in ten succeeds within a 12-month period using conventional methods. Esse scenario motivated Matthew Johnson, the study’s lead author and professor of psychiatry and behavioral sciences, to investigate alternative approaches.
Mecanismo of Behavioral Change and Vital Perspective
The solution appears to be rooted in a profound philosophical transformation. Quase all participants who managed to quit smoking reported a crucial common point: they suddenly understood that their priorities and fundamental values had changed in such a way that smoking no longer made sense in their lives. Johnson notes that “the magnitude of the experience managed to overcome the once insurmountable psychological challenge of quitting smoking.”
One particularly notable finding emerged from the small 2014 pilot study, which involved 15 participants who had been smoking for an average of 31 years. Oito months after receiving two to three sessions of psilocybin-assisted therapy within a structured 15-week procedure, 80% of participants still remained abstinent. Esse’s result contrasts sharply with other behavioral and pharmacological therapies for smoking cessation, which typically achieve an abstinence rate approaching 35%. One participant stated that “it was as if she had been reprogrammed so that touching a cigarette was impossible.”
Histórico of psychedelics in addiction treatment
Exploring the therapeutic potential of psychedelic drugs to alleviate addiction is not new. Durante In the 1950s, researchers used LSD to treat alcoholism, often successfully. Mais Recently, MDMA helped clinical trial participants with alcohol use disorder significantly reduce their drinking or stop completely. Relatos and pilot studies also suggest that ibogaine, a psychoactive alkaloid extracted from the África Central iboga bush, may reduce opioid withdrawal symptoms.
Lynn Marie Morski, executive director of Associação of Medicina Psicodélica, characterizes Johnson’s work on psilocybin for smoking as “one of the most compelling and potentially impactful lines of research in psychedelic science.” Megan Piper, Universidade Professor of Clinical Psychology at Wisconsin-Madison, points out that “there hasn’t been a new Estados Unidos smoking cessation medication in 20 years, so the potential here is exciting,” especially considering that smoking is the leading preventable cause of death and disease globally.
Mecanismos neurobiological and brain plasticity
Gül Dölen, Universidade neuroscientist at Califórnia at Berkeley, says the new findings are consistent with previous investigations demonstrating that psychedelics reopen “critical periods” in the brain. Essas are finite windows of increased sensitivity and malleability that are typically restricted to childhood, when the individual is prepared to learn new things. Nesse specific context, “psilocybin is creating a window of opportunity to learn new smoking-related habits through cognitive behavioral therapy.” The durability of the therapeutic response probably results from the permanent reconfiguration of old brain patterns.
Johnson, a researcher who began his interest in smoking cessation in 2006, chose this habit partly for practical reasons. Comparado to other substances, cigarette biological markers can be reliably and inexpensively measured using a breath and urine sample. Ele was also interested in testing psychedelics on a type of addiction that didn’t involve extreme emotional turmoil or trauma, but rather an equally addictive habit that fits seamlessly into daily life, making it even harder to quit.
Próximos steps and expansion of the search
Johnson and colleagues are conducting a large double-blind, randomized, multi-site trial. Esse study was made possible by funding of approximately $4 million from US Institutos Nacionais and Saúde, the first US government grant in more than 50 years to investigate the therapeutic effects of a psychedelic drug. Participants will receive two doses of psilocybin, which Johnson suspects will produce better results than the single dose from the previous experiment.
Pesquisadores also analyzes participants’ neuroimaging data to identify patterns that can predict successful smoking cessation. Johnson suspects that behavioral plasticity is at the heart of the observed change. “If you’ve been stuck in a pattern for a long time, this can shake you. Não is guaranteed, but it’s a possible way out.”
Study Limitações and future perspectives
Dominique Morisano, clinical psychologist at Universidade of Toronto, describes the new findings as “incredibly interesting,” although she cautions that the results will need to be replicated with a larger, more diverse sample. “This was a small pilot study with highly educated, mostly white participants with a history of psychedelic use. Não It is clear whether psilocybin would be as effective for all people who smoke.”
Johnson recognizes that several questions remain open. Ainda It is not established whether the percentage of people who quit smoking after psilocybin will be able to maintain long-term abstinence, whether the promising results can be replicated in larger studies with different populations, or what risks and side effects may still emerge. Morisano further suggests that therapists could further harness psilocybin’s neuroplastic effects by introducing additional coping mechanisms:
- Exercícios regular physical
- Mindfulness Práticas
- Meditação
- Behavioral anchoring Técnicas
- Integração before, during and after psilocybin session
“Addiction is a complex condition, made worse by many factors, and any truly effective treatment will likely need to involve multiple factors as well,” highlights Morisano. The current context requires creativity in the interventions offered to people experiencing difficulties with addiction.
