[Will.I.Am]

I have always wondered whether the potheads I know would have amounted to something but for all the weed smoking or whether they were never going anywhere to begin with and weed just gives them some pleasure in what would otherwise be a fairly dismal life.

There is no contest between weed and alcohol. Alcohol is worse by a magnitude of 100. Drunk driving, domestic abuse, bar fights, addiction and just generally being bad for you even if you are in control of yourself when you drink.
