Can I do weed once and leave it alone?

I really want to get stoned with my friends. But I'm afraid, I've heard it's not addictive at all, I've heard it is, my friend says him and his best friend smoked it and got high, but he's not addicted. But 2 of my cousins are addicts. So many answers, which one's right? Btw I'm 13. My friend who says he did it is too, and my other friend used to do it with his friends but finally quit, but his friends are still addicted, so does it just depend on the person? Thanks for any answers.

In addition to physical addictions, there are also psychological addictions where a person develops habits and it becomes part of their lifestyle. It's important for all of us to think about WHY we are doing the things we do. Things that offer a benefit for you is good reason to be doing it, because other people are doing it is not a good reason.

I agree with you that "football is great" but people who develop the pot smoking lifestyle never excel at it.
