I'll bite; marijuana is overrated and also it makes your teeth yucky.
Marijuana smokers scream until they're blue
in the face that it's never killed anybody, while writing off as
coincidence that regular marijuana smokers get lung cancer almost as often as their nicotine-addicted
counterparts. Or that marijuana shows up in the blood of those who cause fatal traffic accidents almost as often as alcohol.
The over-all death rate is relatively low precisely because marijuana usage is relatively low, but that will change fast if we put marijuana into corner stores as the senators recommend. The world's biggest tobacco companies have already trademarked brand names like "Acapulco Gold" so if any country ever legalises marijuana, they can move fast to get packs of 20 "Acapulco Golds" into the supermarkets next to the bananas, or to lace existing tobacco brands with subliminal levels of marijuana.
Intresting though, when you mention this to the marijuana
user they always try to change the subject "Hey what about alcohol, what about smokes? I WANTS TO GET HIGH BROTHA, LET'S GET RETARDED BRO!!!" I'm not really concerned with what you do but it should be
common sense to just say 'no'.
