I'd have to disagree with the fact that people are saying that people are using Marijuana just because it's illegal, and to make it legal would "take the fun out of it"
I don't smoke because it's illegal, in fact I've stopped smoking for periods of time because I don't want to go to jail for enjoying a joint.
I smoke because it's relaxing after a long day of work, and it doesn't make me throw up, or have a hangover or act the fool like I do when I drink. I don't like the person I become when I drink.
A lot of people I know look down on me for smoking Marijuana
but in my opinion it's a lot better than getting alcohol poisoning.
It's pretty much impossible to overdose on marijuana... if you smoke too much you just go to sleep, and it's probably one of the best sleeps you'll ever have.
EDIT: also, all this talk about the dangers of mental addiction to marijuana is completely ridiculous. You can get mentally addicted to TV, hamburgers, riding your bike every day, the internet (hello, those like me on elliquiy alot haha) ANYTHING.
it's all a matter on self control and knowing when to stop and what is the limit. For example, I enjoy a good drink every once in a while but I know once I start drinking I won't stop and bad things happen. So I choose not to drink if I can help it.
When I don't have marijuana I don't go into cold sweats, get cranky at my friends, or become sick.
I might be a little sad because I don't have anymore weed, but it's not something I'd go insane over.
all in all, it comes down to the specific person. If you have an addictive personality, you should probably stay away from substances in general.
