"...Ritalin is highly sought after by the drug-abusing population. According to Drug Abuse Warn Net (DAWN) it represents the greatest increase in drugs associated with abuse, and the highest number of suicides and emergency room admissions."
ON HOMICIDES:
A few of the homicides linked to ADHD drugs from a short search ("psychotic episodes" being a feature of ADHD drugs)...
