The US Goverment is My Drug Dealer?

Do you think its true that the reason America wont legalize Weed, Coke, Xtacy and LSD is because they make more money from all the Legal Drugs or Medicines sold (The Presidential Government, The Food & Drug Admin), back in cavemen times they would cure themselves with plants, i think peniciline and pasteurizitation are hella good, but hasnt the market gone overboard with all this comercials and publicity of drugs that no body needs, I mean in so many comercials they name so many synthoms that you gotta have at least one!! They wanna keep you hooked up on that lipozene, extnze, viagra, anti-depressants, anti-inflamatory, tums; there is even a rumor that government administered AIDS to keep people sick and consuming medicines
