i never understood the people who get high and say they go out and accomplish all this shit, they call it getting stoned for a reason. it opens your mind, you become more mentally stimulated, but less physically stimulated. it depends on the type of weed too, i've had weed that gave me the opiate get up and go feeling which is good, but most of the time it doesn't do that.
A lot of those "accomplishments" while they're high are placebo, and once they're sober again, they realize what lazy bums they are.
Marijuana isn't a demon plant with its roots in hell, but it's also not a miracle cure-all. I've never understood people who can't see both the pros and cons.
