A related and useful article from The Economist (Link at the end). I have reproduced parts of it that I found interesting (Heavily edited for telegraphic brevity): "Like many of America’s new generation of users, Ms Scudo's ddiction began in 2000 when, after a hip injury, a doctor prescribed her ... a high dose of OxyContin.. Her prescription was later reduced, but she was already hooked. On the black market OxyContin pills cost $80 each, more than she could afford to cover her six-a-day habit; so she began selling her pills and using the proceeds to buy cheaper heroin. As if from nowhere, Ms Scudo had become a heroin addict." "last year 11m Americans used illicitly-acquired prescription painkillers, more than the number who used cocaine, ecstasy, methamphetamine and LSD combined." "Though Afghanistan accounts for 80% of global opium production, America gets most of its heroin from Mexico. Mexico is now the world’s third-biggest producer of opium, after Afghanistan and Myanmar." "More than half are women, and 90% are white. The drug has crept into the suburbs and the middle classes. And although users are still mainly young, the age of initiation has risen" http://www.economist.com/news/united-states/21633819-old-sickness-has-returned-haunt-new-generation-great-american-relapse http://www.economist.com/news/united-states/21633819-old-sic...
