Why has being drug-free become uncool all of a sudden?

Since marijuana use and support for legalization is at an all-time high and the fact that drug-free people are becoming more and more discriminated against, it makes me feel that the majority of Americans have a drug problem. There was a time not too long ago where druggies didn't dare to speak openly about their drug use. They were confined to the skid-row alleys where they belong. Now it's the other way around. I'm tired of hearing about the constant support for legalizing drugs, especially marijuana. Supporting legalization is something only a stoner would do. All druggies need the f*cking crap kicked out of them.
