I worked in a big city ER for 20 years.Heroin ODs were a dime a dozen...Narcan,an opiate antagonist,was ordered by the crate.Ten bucks says that within a few years this new drug will be withdrawn from the market due to lawsuits and,perhaps,bad publicity as well.
Since they just killed my Vicodin prescription due to the high acetophetimin content, this will be a welcome relief.
I did not know it by that name -- had to look it up. Ah, yes, Naloxone; I know the chemical/generic name. Used it in the lab.
