Marijuana...Good for you?

I love the second sentence here from the article above...

"Other evidence from population studies suggests that people who regularly smoked marijuana in the 1960s and 1970s are less prone to develop Alzheimer's than people of the same age who did not. Yet many other studies show that long-term regular marijuana use -- 10 years or more -- has a negative effect on a person's ability to pay attention to more than one thing at a time and to learn and remember new information. "

Geez, I don't know anyone like that. Like what? Hey, did I leave the iron on? Dude, South Park is friggin hilarious. Man, I can't believe I used to not like tomotoes in my grilled cheese.
