One Weird Trick Reduces Binge Drinking on College Campuses By Nearly 10%

Clickbait-y title aside, a recent study confirms what we at Twenty-One Debunked have always known.  When examining substance use trends among college students from 2008-2018, it was observed that recreational cannabis legalization was associated with nearly 10% LESS "binge" drinking by students over the age of 21.  That is of course not surprising, given that alcohol and cannabis tend to be substitutes, and the legal age limit for both substances is 21 in all such legalization states so far.  No such effect was observed for students under 21, and no other effects were observed on trends for any other substance use (including nicotine use, illicit drug use, and prescription stimulant, sedative, or opioid misuse) among students under or over 21, except for a modest increase in the (mis)use of sedatives among students under 21 (but not over 21) for whatever reason. (So much for the long-debunked "gateway" theory).

We at Twenty-One Debunked believe that if the age limit was lowered to 18 for both alcohol and cannabis, the benefits of the aforementioned reduction in "binge" drinking would extend to students under 21 as well.   In any case, cannabis legalization looks like a net public health win on balance.

So what are we waiting for?
