Marijuana isn’t (physically) addictive, and no Freeper has ever told you “marijuana was the perfect substance that has never had a negative effect”. When you engage in ridiculous hyperbole like that, over and over, you lose all credibility.
Since you are all-knowing, please explain marijuana to me?
Just because the government told you that, doesn't make it true. If marijuana isn't addictive, then how come people "introduced" to it have to use it religiously.
Example, that director Kevin Smith, was 35+ when some actor introduced it to him, now, by his own admission, is smoking it almost all his waking hours.
