There's nothing addictive about marijuana, like !K_A! says. It's the "high" you get when you use it. Keep in mind that the people who are against drugs (eg. teachers, government, etc.) turn something very small into something very big. Like lets say a pothead was sitting on a bench next to a scientific professor who works for the government and the scientist is taking note of the pothead. Now the pothead goes and says "God, a bowl of chronic would be nice right about now, sitting on this boring bench waiting for teh bus". Now the noob professor he's like "OMFG, this guy's ADDICTED to marijuanana." So he goes and makes videos about the scientific facts of marijuana and how they can be so-called "addictive" and sends it to all the junior high schools around the country. That way when they get to high school they are all D.A.R.E. noobs but eventually start smoking and are coke-heads by the time they're 20.
