Now cannabis is not physically addictive like opium or alcohol... but it can certainly become very psychologically addictive. Studies have shown that and anyone in Marijuana Anonymous can tell you it first hand. Drugs that alter your mental state can be particularly addictive in that way. A person may start to depend on the substance for their enjoyment of life... that is the problem. You should see the benefits to being high, and the benefits to being sober... and be able to enjoy both in your life.

So I agree with Ben. It's the difference between use and abuse, between enjoyment and dependence. Enjoying something that promotes joy in your life, or peace, or fun, or expression, or whatever... that is wonderful. But depending on a substance for those feelings is a bad thing. You should be able to have similar feelings without weed, and just use the weed as a way to experience those feelings from a different angle... and in moderation at that. Moderation is the key. I'm not drawing a line and saying how much is abuse. Each person is unique and has to decide that for himself.
