Marijuana has many bad effects. Every single source other then Marijuana users themselves says so. I will not try it, and will never. It's obviously something one turns to when depressed, because they can't find something constructive and useful to get their mind off the stress. Watching a movie, reading a book, playing a videogame, all those will take your mind off of troubles. You don't need to pay for it, and since it's illegal in many parts, you shouldn't have to break the law for pleasure. It's a stupid thing to do. Find something better to do with your time.
