According to your logic, it would be ok or not ok for society to legalize cocaine?

So it would logically follow that we do need one less substance to dumb down society and that criminalizing alcohol for adults would be a good policy. Problem is, that conclusion is false, and therefore so is your premise.

According to my logic, "we don't need one more substance to dumb down society" is an invalid argument against legalizing cocaine.

Criminalization of cocaine has had no more demonstable success than criminalization of alcohol, marijuana, or any other mind-altering substance. However, proceeding cautiously with change is a conservative principle; so I support legalization of only marijuana as a first step, and taking any next step only after we've assessed the effects of that first step.
