You're an idiot.

There is nothing in marijuana that can make your body physically addicted to it. Therefore, it's a psychological addiction.

What's hard to understand about this people? If you are addicted to something, it's either because of a chemical dependancy that your body has formed, or you're psychologically addicted to it.

Chemical dependancy could most likely be shown to be a different thing than physical addiction, but they are pretty much in the same boat, and physical addiction is also caused by a certain chemical.

Marijuana has no addictive chemicals in it, and people who smoke marijuana are not physically addicted to it. What's addictive about marijuana is the feeling you get when you use it, therefore it is a psychological addiction.
