In 1999, Pediatrics published
research by Joseph Biederman, MD, of Harvard Medical School, which concluded that
ADHD boys treated with stimulants such as Ritalin are significantly less likely to abuse drugs and alcohol when they are older than ADHD boys who are not treated."
And it was conducted by Biederman as I suspected. He was employed by Novartis, the makers of Ritalin, at the time the study came out.
