> Ever since it became legal I have friends who spend majority of their day high. Of course, when confronted, they say it's not addictive and they dont have a problem. As we know this is the first sign of a very serious addiction.

Before it became legal, I'm willing to bet those friends spent a majority of their day doing something equally unproductive. Be it playing video games, or watching tv, whatever $couch_potato_activity. And they're probably just doing the same stupid thing while high, because it's even more fun that way.

It's easy to villify a drug for what happens either way, you're not proving a causal relationship. Pot and being a lazy slob go dovetail quite nicely, just like pizza and beer. Nobody blames pizza and beer for the fat stained-shirt slob who never gets off their ass.
