Hi there ~
I understand your concerns. Overdose of klonopin
is not the reason for the white foam in the mouth. The discontinuation of prolonged use of klonopin may cause the person to have seizure
like activity which is probably the reason the dead body was having foaming in the mouth. I certainly would check with the doctor who declared the death and the one the performed the post mortem if the patient in fact was having a history of seizures as well.
I hope this helps. Take care of yourself and have a lovely day!
