I don't think legalizing crack cocaine will help with the problem ...
My neighbor died huffing PAM - spray grease - thru a washcloth. My cousin passed out sniffing the gas can in the boat.
Shall we criminalize household chemicals & petroleum products? How about the weeds & mushrooms in your yard?
Is it your idea that if we can just eradicate pot, coke, heroin, meth, etc. that the problem is solved? Dream on!
