My thoughts are its both. I had a cousin on an array of those pills. He got nasty with his mom. I had just gotten out of th  4125  e military and was still....in that mind set. Long story short, I put the fear of almighty GAWD in his soul. To this day 35 years latter.  He behaves around me. Part of the problem is a lack of discipline. Parents let the drugs "fix" the problem. The other is the drugs and sometimes the therapy. My cousin recovered after his mother took the drugs away from him. Some peoples chemistry can not tolerate them at all. Look at the list. It is MASSIVE. And those kids are as youg as 11.
