I will admit to a couple of mistakes here.
I am using anecdotal evidence and I should have said that in my experience more kids have access to drugs than alcohol.
In every survey I've seen, teens have responded that marijuana is easier to obtain than alcohol (I don't know about cocaine, heroin, or meth). Yet teens use hard to get alcohol 2:1 over marijuana.
I say because alcohol is legal, and the resultant message is that society thinks that alcohol isn't so bad.
