Isn't it just the usual logistical curve scenario? Rapid growth to meet the desired need, until market saturation and users are dying off faster than they can be born? From a creationist standpoint all people are equally likely to become addicted so you can use economic/cultural data as a proxy for susceptibility, however in the real evolutionary based world we have been brutally selecting for non addiction susceptible genetics and small scale culture for a long time, so at some point you'd expect a crash in addiction rates. Something like cig smoking can't be bred out because the addicts die horribly in their 60s long after reproducing, but every teenage heroin overdose for the last couple decades is a permanent culling of the herd of people who can't handle their chemicals responsibly. From a cultural standpoint I'm old enough that "Heroin just is not something our people do" works pretty well until it doesn't anymore, its interesting the study quotes seem to imply a grasp at any straw other than making heroin culturally unacceptable again, which ironically is probably the only thing that will work long term.
