Now bear in mind...my expertise as an SA counselor only extends to addicts. Just how the users amongst the other 90% of the population will respond to legalization is a guess for me. I want to be clear. I'm intersted to hear your experience as a user, and how you think legalization would affect things.
My main reason to legalize is that drugs are made dangerous because they are illegal and thus not subject to proper controls are other consequences of current drug policies. Not to mention organized crime and violent foreign cartels. I think drug usage is sometimes one of society's ills that won't be solved by criminalization, my example is the Volstead Act.
