Im not sure how much clout the tobacco lobbyists have in Congress and the Senate anymore. Im sure they can still get things done but I bet the health insurance/pharma lobbyists are much more prevalent. Not to mention Gun lobbyists. Im sure the only reason our government hasnt legalized and regulated marijuana is because the politicians cant agree on the best way to screw the public over. If they ever do legalize it, I think the real potheads will still be buying it through street dealers and such because the government regulated product will be shitty.
