I hear music much better when high, same goes for the other senses. If I get into something whilst high, I'm usually 110% concentrated on what I'm doing. I have a deeper perception of things, I think differently but I wouldn't call it impared. Gimme some of that weed !! Weed actually helps with some cancers. I can't really disagree with the others tho, they're true to some extent.
I wouldn't mind if it was legalized. I'm not a regular user, but I have a few friends that are. I don't think it being legalized would drastically change the amount of people that use it. Also I think there are quite a few misconceptions about it. A lot of people that I've talked to about this seem to be under the impression that it's as hardcore as some pretty illicit drugs. To be honest I think marijuana is kind of benign. I wouldn't endorse it, but I don't think it's as horrible as it's made out to be.
