Dude, do you really assume EVERYONE who supports drug decriminalization/legalization is a druggie themselves? The only illegal drug I've ever done is marijuana (which isn't even illegal in my area anymore) and I haven't done it in about 20 years. I barely even drink. Do you think Ron Paul is an addict or something instead of someone who's guided by libertarian principles? I'm a left libertarian.
Also, you've just exposed yourself as a HUGE hypocrite. Based on your own logic, you should self-deport immediately...
