Cannabis research — studies & evidence
Cannabis science without the marketing: this hub gathers study-based articles and data that back our guides and calculators.
We aggregate peer-reviewed Swiss and international studies since 2015 — University of Bern, EPFL, Sucht Schweiz and international bodies like DSM-5 and EMCDDA. Each entry links methodology, sample size and limitations and is reviewed each quarter.
