In the pantheon of drugs, marijuana gets a lot of coverage because of its popularity. In fact, in some anti-drug circles, a drug's danger is directly related to how popular it is. So for them, mary-jane is the work of Satan.
Pro-drug people like to point out how harmless marijuana is. I always knew that was a load of crap. Any substance that alters your neurochemistry can be dangerous, no matter how little it does so. And anyone who has had a friend who's done a LOT of pot knows the full effects of "burn out."
I've also been loathe to talk about how marijuana is still dangerous because the last thing I want to do is give any kind of credence to the drug-hating, alarmist twits that usually make up the anti-drug movement. But I think it's time people started laying some scientific smack down on the drug-loving, hippy twits who make up the pro-drug movement.
