Survey: Ayahuasca for PTSD

A new anonymous questionnaire is gathering preliminary data about the potential risks and benefits associated with taking ayahuasca as a therapy for posttraumatic stress disorder (PTSD). The data collection is being sponsored by the Multidisciplinary Association for Psychedelic Studies (MAPS). Jessica Nielson, Ph.D., is the Principal Investigator for this study.

Purpose of the survey

We are developing a protocol to test if Ayahuasca therapy and integration is safe and effective for PTSD. Our goal is to gather existing data from anyone who has been diagnosed with PTSD (current or previously) AND has also tried Ayahuasca after their diagnosis. We welcome participation from people who do not have a confirmed diagnosis of PTSD, but have tried Ayahuasca and want to share their experience.

Eligibility Criteria


You are invited to participate in this survey if you fulfill the following criteria:1) You are at least 18 years old; 2) You read, write, and speak English fluently; 3) You have taken Ayahuasca in any type of setting; 4) You have a past or current diagnosis of PTSD (optional)

What kind of information will I be providing?

At the beginning of the survey, you will be asked questions about your background (e.g. age, gender, ethnicity, spiritual and/or religious beliefs), followed by questions about whether you have ever been diagnosed with PTSD, details about your Ayahuasca experience(s) and any changes you may have noticed in your PTSD symptoms, substance use, depression and sleep quality. Some of the survey questions may make you feel uncomfortable or raise unpleasant memories. You are free to skip any question that are optional, and all required questions have the option of “prefer not to answer”
