Using psilocybin to help people quit smoking

5-HT2A Agonist Psilocybin in the Treatment of Tobacco Use Disorder

NIH-funded research Johns Hopkins University · NIH-10669236

This study is looking at whether taking psilocybin, along with cognitive behavior therapy, can help people quit smoking better than using nicotine patches with the same therapy, and it's open to a diverse group of participants who will be paid for their time.

What this research studies

This research investigates the use of psilocybin, a compound that activates the 5-HT2A receptor, in combination with cognitive behavior therapy (CBT) to assist individuals in quitting smoking. The study will be conducted as a multi-site, double-blind, randomized clinical trial, comparing the effectiveness of psilocybin against nicotine patches, both paired with CBT. Participants will be recruited from diverse backgrounds and compensated for their involvement, aiming to improve smoking cessation rates among a broader population. The trial seeks to validate previous findings and address gaps in participant diversity and socioeconomic status.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults who are current smokers and seeking help to quit smoking.

Not a fit: Patients who are not currently smoking or those with contraindications to psilocybin may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a novel and effective treatment option for individuals struggling with tobacco use disorder.

How similar studies have performed: Previous studies have shown promising results with psilocybin for smoking cessation, but this double-blind trial is a novel approach to further validate its efficacy.
