rp: What's important is what teens use. And teens use alcohol 2:1 over marijuana. I say that's due to the legality of alcohol. 253
Legal status has nothing to do with it:
When LEAP (Law Enforcement Against Prohibition) speakers give presentations to college students they ask: "Is the reason you don't do drugs because they are illegal?" Almost nobody raises their hand.
It's recklessly naive to assume that legal status alone would prevent the vast majority of potential drug users from using drugs. It might matter to those on the fence, but those people, by and large, aren't going to turn out to be the type of drug users who turn into societal problems. And those drug users who are societal problems demonstrably could care less about their drug of choice's legal status.
