Caulkins on (quasi) medical marijuana

How come the number of “medical” marijuana users in some states is so large compared to the total number of self-reported marijuana users? Is there an epidemic of chronic pain among otherwise healthy thirty-year-old men who have been smoking pot for years?

Jon Caulkins of Carnegie Mellon is the lead author on a book on marijuana legalization scheduled for publication next spring. The rest of the team consists of Angela Hawken of Pepperdine and me (who worked with Jon on Drugs and Drug Policy, part of the same series from Oxford University Press) plus Beau Kilmer, who heads the RAND effort studying the possible effects of legalization.

Jon and I don’t come from the same place culturally or politically, and he’s extraordinarily smart (not to mention conscientious and kind), a combination that makes working with him – as I’ve been doing off and on for twenty years – both a challenge and a pleasure. Angela and Beau bring still different personalities, views, and skills to the enterprise – along with razor-sharp minds –  but so far it’s running very smoothly.  The concluding chapter of the new book will consist of a brief statement by each author laying out a preferred option; I can’t predict any of them in detail (even my own thinking keeps shifting) but I expect the four statements to embody lots of disagreement.

Jon and I agree more about facts than we do about values or policies. For example, he’s clearly right to say that the profile of “medical” marijuana users looks like a profile of recreational drug users, not a profile of patients, and that their sheer numbers in some states suggest that most of the recreational market is now accessing its supplies through quasi-medical channels. And that doesn’t even count the people whose recreational needs are supplied by friends with medical cards. Whether he’s also right to say that the Justice Department would do well to crack down on the scam is less obvious, at least to me.
