My friends get bored and they substitute their boredness with getting high.
It's really dumb, and they're wasting a ton of money.
However, they're still my friends and it's pretty funny when they're stoned.
Though I believe pot should be legalized, and have the same laws as alcohol. (Don't go to work while under the influence, etc)
People that are against it are obviously very ignorant, they don't know anything about pot. Alcohol is much worse.
