Around 1 in 20 people have personalities such that they're prone to addiction, to the extent that it can cause them to make questionable decisions. Drinking, smoking, sex, heroine, gambling, porn, work, party drugs, Subutex, anti-depressants, whatever, you name it. We need to stop prohibiting whatever activity/substance people actually get addicted to because its essentially arbitrary, and start compassionately treating the root psychological causes.
