Two Theories on Crystal Meth

The Times today has an article discussing the possible spread of crystal meth to the East Coast big cities, Trashy or Not, a Drug Peril Creeps Closer. So far it hasn't happened

1. One is ecological--"The theory is that addicts well supplied with cocaine in big cities haven't craved a substitute, which suits traffickers just fine since their suppliers in Colombia and elsewhere don't want the competition from largely domestic brewers."
2. The other is classist--"The general impression among African-Americans is that this [methamphetamine] is a white-trash drug," said Sally L. Satel, a psychiatrist at the American Enterprise Institute who has interviewed drug addicts about methamphetamine. "African-Americans recoil from this drug. They told me they think it is a very low-class kind of drug, and there was a kind of revulsion to it."
