Worthless comment, right? If you'd read the link you'd know I'm quoting directly. It cites studies, like this one: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4392651/

...which declares other correlations: "cannabis use has been linked with increased use of other drugs, including opioids" again adding "however, a causal relationship has not been established." Should we assume the bad stuff is causal, too? I don't believe we should.
