Introducing the world’s first mobile microdosing study.


A correlational study on the effects of microdosing psychedelic substances on cognitive performance and menta​l health.


You're invited to join

Gain an increased awareness of how microdosing affects various aspects of your own health and well-being or how measures of your health and well-being fluctuate over time.

Participation is completely anonymous. All data collection will be self-administered and your identity will remain anonymous. You will not be asked to identify your name, email, or d​a​t​e of birth.

Participation in this study asks for approximately 3 hour​s of your time over a 3-month study period, conducted completely within the Quantified Citizen mobile app.

Both microdosers AND non-microdosers needed. We are interested in observing those who are currently microdosing, and those who are not.

Who is conducting this study?

Launched Nov 15, 2019 on the Joe Rogan Experience, this 12,000+ participant (and counting) study is being conducted by Quantified Citizen (a mobile health research company) in collaboration with Dr. Zachary Walsh, Associate Professor in the UBC Department of Psychology, Dr. Pamela Kryskow and the Multidisciplinary Association for Psychedelic Studies (MAPS) Canada. This study was reviewed by the University of British Columbia, Okanagan’s Ethics Review Board.

How does it work?

After downloading the Quantified Citizen app, you will be asked to complete an intake questionnaire, including basic demographic information, basic medical history, and self-reported use of psychedelics.

You will then be asked to complete a baseline battery of self-administered cognitive performance and mental health assessments via the app. This entire intake process will take approximately 30 minutes.

Regardless if you are microdosing or not, you will be asked to go about your normal daily routines for up to 3 months, completing brief daily questionnaires that should take you about 1 minute each day. You will be asked to repeat the battery of cognitive performance and mental health assessments (same as the baseline) on a monthly basis that should take you approximately 20 minutes each time.

Finally, at the end of 3 months, or whenever you decide to finish, you will be asked to complete a short closing survey that will take approximately 5 minutes. Participation in this study asks for approximately 3 hours of your time over the 3-month study period.

You do not need to use psychedelics at any dose to take part in this study; we are interested in observing those who are currently microdosing, and those who are not. You will NOT be provided with psychedelic substances, or with instructions on where to obtain them or how to use them, as part of this study.
