If your concerns were based in fact, it might be other than tendentious.
As it is, alchohol does far more damage that all drugs.
Start advocating against alcohol and how it messes up people's lives. That would help more people than railing against pot.
I read a book by a former mob hitman and he said the only thing that would stop the drug trade is legalization. It would put the mob out of business. Why do you think we have so much crime in this country? People are NOT going to stop taking drugs. Give people what they want and you can control it more.
