AFAIK part of the problem is that the people who don’t drink alcohol include those who no longer drink any, but used to, i.e. recovering alcoholics or people with other health issues.

For any drug but alcohol, studies wouldn’t mix previous consumers in with those who never consumed any of it, but here, afaik, funding from booze companies complicates the situation.

Yes, BUT! it would look cool as hell being useless :D
