I think that the commercials are pretty good. I kind of took them as "marijuana = lowered inhibitions = stupid stuff happens".
The fact that they are "real life" kind of situations that teenagers might relate to, like smoking up at a party, in the car, in your parents house, make them more realistic than "if you smoke weed, then you are a dirty hippie who is homeless and smelly and deals with shady characters" image.
But with that said, marijuana supporting terrorism?
Yeah, right. Your dealer is probably a bored, middle-aged white guy going through a mid-life crisis who steals it off his mom who grows it in her garden for glaucoma."
