Researchers at Maastricht University are working on a research study about mescaline use, including synthetic mescaline, peyote, and San Pedro. This anonymous internet survey asks questions about your experiences with these substances, including the short-term and long-term effects. If you have ever had such an experience, we would greatly appreciate you completing the survey. If you know of others who have ever had an experience with mescaline, please send them the link and encourage them to participate. This includes people who had such an experience long ago.

The study will permit a better understanding about the phenomenology, interpretation, and acute and enduring effects of mescaline. The hope is that, ultimately, they will receive thousands of responses to the survey so that they can better understand the experiences after ingesting mescaline, resulting in valid and reliable measures of such experiences to use in clinical research.

The team has conducted survey and laboratory studies investigating the phenomenology of psychedelic substance use and this new survey is an important extension of our published and ongoing research. If you are interested in participating or would like to know more about the study, please click the link below to the secure study site. We anticipate that it will take you approximately 30-45 minutes to complete the survey. Your participation is completely anonymous.
