> if they want to use and continue to throw their life away

This is exactly the marginalization he was talking about. Some of the smartest people I know love hard drugs and are very successful, are they throwing their life away because they use on a regular basis?

Maybe you are only talking about the outright stoners that just get high every day, but are they really any different to the other lazy people that don't work? Not doing anything ever is generally what I would consider to be throwing your life away.

I don't think drug use has much to do with throwing your life away, apart from the depression that comes from being marginalized. People that wish to throw their life away will do so with or without drugs.
