I was asked by the National Institute of Health to be their scientific discussant on the effects of these drug [Ritalin] at a big conference they held. Beforehand, I reviewed all of the important literature on the issue. Even with experiments on animals. When they're given these drugs they stop playing; they stop being curious; they stop socializing; they stop trying to escape. We make good caged animals with these drugs. And we make good caged kids by knocking their spontaneity out of them. And, Michael, the other thing is that these drugs enforce obsessive behavior.
