The thing about substance abuse is that you don't have limits. You don't say when. For a lot of the hard drugs, there are laws that make the very use of the substance criminal. But that's not why substance abuse is a problem. We all know people who can taste or dabble in hard drugs -- a line of coke here, lsd there --- and never develop a bad habit. But we also know people who cannot stop drinking. And drinking is legal. So just because marijuana is becoming more acceptable and even legal, consider that a gift. You still have a problem with it if you have a problem. I put that statement up to disagree with it because I've heard it now and again. What are your views?
