How to give advice for lower-risk cannabis use

Introduction As a parent, sometimes I have given overly-cautious advice like: “The only way to guarantee not having a ‘drug problem’ is to not use drugs.” While the statement is true, it is totally useless advice for those who choose to experiment or consume a psychoactive drug with the potential for problem use.1 A better approach is to provide factual, evidence-based guidelines after the “overly-cautious advice.” Fortunately, Fischer et al. provide just that: evidence-based guidelines for lower-risk consumption of cannabis.
