The people who are overdosing from the Fentynal problem are doing so mostly unknowingly. Dealers are "spiking" their heroin with it in an effort to boost sales as when someone OD's from taking heroin, the user community takes that as being a great batch of heroin and the OD being caused by someone who is not very tolerant to heroin. It's a sick and disgusting game that dealers are using. Again it's not the drug and generally not the users who are OD'ing that are bad, it's the sick twisted dealers out to make more dope money!
