That's pretty disingenuous. 23 million Americans have used drugs/alcohol to the point of needing treatment: http://thechart.blogs.cnn.com/2011/09/08/study-22-million-am...
That's 7% of the population, including children under 12. Take the pre-peer-pressure group out and it starts to look more like Russian Roulette. I'd hardly call that a risk worth taking.
