If you believe that drugs add value to people's life, then you've chosen the world you want to live in. I chose to believe that (addictive) drugs are really a tax levied on people with weaknesses to be exploited (we all have weaknesses that can be exploited). The purchase of addictive drugs doesn't create value but redistributes wealth from the folks that are weak to the exploiters of that weakness. I don't value drug wealth. That's the world I choose to live in.

I don't believe that (see the devil's advocate tags...). But, some people obviously do.
