Yeah, I used to mostly blame the government for drug addiction problems.
Like, by making heroin illegal, the result is that it's expensive and cut up. I mean, if you could get it at any gas station along with your coffee and smokes, then folks wouldn't be breaking into houses and pawning their souls. And if the doses were known, you'd probably see fewer overdosesl. Likewise, if it weren't illegal, you wouldn't have addicts coming out of jail after a forced week or more long detox and accidently overdosing. Seems almost like a lot of addicts intentionally take dangerous doses out of depression, but even that very depression may have resulted from all their financial and legal problems that have their origin in the government regs.
On the other hand, long before becoming addicts, we are well aware that dope is very expensive and illegal. So, by analogy, if the government were to attach known negatives to, say, chocolate (beyond just calories--like, say every bit of chocolate was laced with a chemical that would kill a person if they ate it over a ten year period or so). In that case, if we still had "chocoholics" running around, then it would be very obvious that they had some psychological issues (which, by my hypothesis are related to an inability to weigh pros and cons)...they couldn't just say, "Man, I'm just a normal person who enjoys chocolate, but I'm being screwed by 'the system'".
