Everyone is on medication for depression. They can get serious even when they know they should.
A caller to Rush yesterday brought up the very interesting theory that one reason 75% of the kids in government schools are diagnosed with ADD, ADHD, autism, etc., and placed on psycho-active drugs like Ritalin (among many other drugs, including anti-depressants) is so that one day the government can deny them, as grown-ups, "permission" to purchase firearms based on those "mental health" issues.
So the reason for all the drugging of kids in the schools may go way beyond merely making life more convenient for lazy parents and lazy teachers - - it may be a long-range setup for dismantling Second Amendment rights for most people. Once that's accomplished, those who are left with government "permission" to own firearms can be dealt with in other ways.
