Updated on September 7, 2015: This report provides a comprehensive overview of the scientific research on major claims made about cannabis use and regulation. For each claim, the relevant available scientific evidence is presented and the strength of the scientific evidence in support of the claim is determined.
Readers will notice that none of the claims are strongly supported by the scientific evidence, reinforcing the significant misrepresentation of evidence on cannabis use and regulation. The ICSDP hopes that the evidence contained in this report meaningfully contributes to the global conversation around cannabis policy and helps policymakers, as well as general readers, separate scientific evidence from conjecture.
Please note that this report should be read in tandem with Using Evidence to Talk About Cannabis, a complementary guide to having evidence-based discussions on cannabis use and regulation.
