Son of a bitch Spitzer is an idiot!
He's trying to make a false correlation between available drugs (legalization or decriminalization) and growing addiction rates, he then goes on to suggest if addiction rates rise, wouldn't that mean that addiction rates in kids would rise, as kids are more susceptible to using drugs.
Spitzer, how many alcoholic kids do you know? How many kids under the age of 18 do you know who habitually smoke cigarettes?
If heroin became legal tomorrow, why would I go buy it? How does legalizing a substance increase consumption? It seems keeping substances illegal and unregulated is what leads people to seek them out, specifically kids.
