There is no doubt in my mind that this woman was on psychoactive drugs when she made the decision, and carried out the action, killing her children.
Every single mass murderer, in or out of schools, in the US in the last decade or more has been on psychoactive drugs. Many, many people on these drugs kill themselves and sometimes they kill others along the way.
These drugs do not decrease deaths, they increase them. Psychoactive medication does that. Often.
As a psychiatrist who has practiced drug-free medicine and psychiatry for 44 years, I can definitively state that nutrition, neurobiofeedback and other safe, effective means work while drugs do not, and have disastrous consequences.
You really do not have to fill that prescription! And since these drugs inevitably, often permanently damage the brain and body, they should not only never be taken, but NEVER given to children.
