ClinConnect Summary

This clinical trial is studying the effects of psilocybin, a naturally occurring substance found in certain mushrooms, to see if it can help people stop using methamphetamine. The researchers want to find out if using psilocybin can support individuals in their journey to quit methamphetamine and improve their overall quality of life. They will look at how this treatment affects cravings, emotional well-being, and cognitive abilities. The trial is set to take place in Northern Louisiana and is currently not recruiting participants.

To be eligible for this study, participants must be between the ages of 25 and 65 and have identified methamphetamine as their drug of choice. They should have been in a treatment facility for at least a week and must be committed to stopping their meth use. Participants will attend a few sessions before receiving the psilocybin treatment to build comfort with the research team and discuss their goals. After treatment, they will have follow-up appointments to monitor their progress. It's important to note that this study has specific criteria for who can join, including health assessments to ensure safety.
