There was a post yesterday on /r/smallbusiness about helping an employee who had a heroin addiction and helping one who had a gambling addiction. The overwhelming consensus was that the gambling addiction was worse, which is not what I would have expected. But the logic made sense from the financial perspective: you can only use so much heroin in a day, but you can spend an unlimited amount on gambling.
I feel like this is backwards? When you reach your heroine limit, you die. It's pretty final. And, most people don't have unlimited money with which to gamble.
