Legalizing pot carries risks. So does prohibition.

My letter to the WSJ about Bill Bennett’s “16.2 million marijuana addicts.”

As predicted, the Wall Street Journal refused to correct the Bennett/White op-ed that strongly implied (without quite stating explicitly) that I believe cannabis legalization would sextuple the rate of cannabis dependence to 16.2 million. (My previous whining about that here.) However, the Journal did publish my letter, with only helpful edits and an accurate headline that’s a pretty good haiku-length statement of the case.

Like the original article, the letter is behind a paywall, so – on the off chance that some RBC readers don’t pay tribute to the Murdoch empire – I’ve pasted it in below.


Legalizing Pot Carries Risks, but So Does Prohibition

To the Editor:

William Bennett and Robert White (“Legal Pot Is a Public Health Menace,” op-ed, Aug. 14) cite my research as support for their claim that the legalization of cannabis would mean creating 16.2 million “marijuana addicts.”

Not only is the attribution false; the claim it purports to buttress is absurd. I made no such prediction, and the idea that legal cannabis could create more addicts than legal alcohol doesn’t pass the giggle test. It would be astounding if the actual number were one-third as high as Messrs. Bennett and White project

Cannabis legalization on the current alcohol model—low taxes and loose regulations—would indeed risk a large increase in the extent of cannabis abuse. That is why some of us are working hard for high taxes and sensible regulations on cannabis, as well as stronger controls on alcohol, which is after all a much more personally and socially dangerous drug.

Cannabis legalization in any form will create some harm; every drug policy has disadvantages. But against that must be set the enormous harms from cannabis prohibition: $40 billion a year in illicit revenue, some of it going to violent criminal organizations in Mexico; tens of thousands of people in prison; and more than half a million users arrested each year.

Our goal should be to eliminate as much as possible of the damage from prohibition while minimizing the harms that would result from a badly designed legalization.

Cannabis, Bill Bennett, and the technique of selective reading

A friend emails, “Bill Bennett read your book … or at least every other page of it.”

A friend emails, “Bill Bennett read your book … or, at least, every other page of it.”

Well, yes. Bennett and his sidekick Christopher Beach, in using the Caulkins et al. Marijuana Legalization book to support their argument against legalization, illustrate the point made here yesterday about the contrast between analysis and mere advocacy. To an analyst, every course of action* has advantages and disadvantages, which ought to be carefully weighed against the advantages and disadvantages of its alternatives. To a mere advocate, the course of action he prefers has only benefits, while the courses of action he deplores have only costs.

Since Beach and Bennett chose to base their argument on our book, (albeit without providing a link to it), it’s easy to see their principles of selection in action. They start out by mis-stating the book’s viewpoint and purpose:

In their book Marijuana Legalization: What Everyone Needs to Know, Mark Kleiman, Jonathan Caulkins, Angela Hawken, and Beau Kilmer—all of whom support the legalization of marijuana in some fashion—report …

This account suggests that the authors of the Weekly Standard essay never quite finished the book. While the first fifteen chapters, in Q&A format, are entirely collective products (I suppose in this context I can’t say “joint products”), the final chapter consists of four individually-authored essays. Of the four authors, only Angela Hawken favors legalization on the alcohol model. I’m clearly for legalization, but just as clearly against commercialization, concluding “So my first choice—not what I think will happen, but what I would like to see happen—is permission for production and use through small not-for-profit cooperatives, with a ban on commerce.”

Beau Kilmer points out how uncertain the whole proposition is, and devotes his essay to arguing that, if legalization is to be tried, it ought to be tried in an experimental mood, with, for example, sunset clauses. He adds:

Given the dearth of evidence we have about legalizing any of these activities, I am not convinced that jumping from one end of the continuum (prohibition) to the other (commercial production with advertising) is a good idea. Indeed, given the concerns about marijuana companies working hard to promote use, nurture heavy users, and keep taxes low, implementing the most extreme alternative to prohibition could be a really bad idea.

And Jonathan Caulkins – in fact the lead author of the book, though  Beach and Bennett list my name first – comes down more or less in the Beach-and-Bennett camp, starting his essay with  “I would vote against legalizing marijuana … ” (though he lists a grow-your-own approach as a possible “middle ground”). Jon concludes:

About half of all days of marijuana use come from people who self-report enough use-related problems to meet criteria for substance abuse or dependence with respect to marijuana or another substance. Does the happiness a controlled user derives from using marijuana on a typical day offset the unhappiness of someone else spending a day harmed by and/or struggling to control problem drug use? In my opinion, the answer is no. In a free society there are plenty of other ways to have fun without insisting on a right to use something that becomes a stumbling block for others.

Why should Beach and Bennett want their readers to believe that the authors of Marijuana Legalization are all legalization advocates? Continue reading “Cannabis, Bill Bennett, and the technique of selective reading”
