Reducing Cannabis Use Disorder

Marijuana policy is heading inexorably toward the model we use for alcohol — weakly regulated commercialized legalization, with taxes that are too low. That’s been a public-health disaster in the case of alcohol. Cannabis isn’t as dangerous, but there’s still no good reason to repeat that mistake. Taxes should be higher and marketing restrictions tighter; there’s even a case for keeping commercial enterprises out of the industry altogether and restricting sales to consumer-owned co-ops.

But here’s a more outside-the-box idea, designed to help people exercise self-restraint about how much cannabis they use and how often: a system of user-set monthly purchase limits.
