The study should also answer questions of perceived advantages and preferences based on demographic factors (gender, age and country), previous experience with recreational cannabis, diseases or symptoms, and involvement of a physician in the use of cannabinoids.

It is intended to publish the results in a scientific journal. Major results will be presented on the IACM website.
