Then why do the drug ads warn about suicidal thoughts can be a side effect of these psychotrophic drugs?
There is an immense difference between suicidal thoughts and planning and executing mass murder.
In clinical trials, if even one person out of 2,000, has any side effect, the pharmacy will list that as a possible side effect.
If one person out of 2,000 has a rash during the trials, rash will be listed as a possible side effect.
