NARCAN Should the drug abuser be billed for the cost of this drug?

I am watching the local news. Our Police had some vials of margam, That is a drug to revive people who have given themselves an overdose of drugs. It is $75.00 per injection. Why on earth shouldn't the druggie be expected to pay for the ambulance police and drugs to keep their drugged out butts alive? Someone is complaining that it isn't fair. Not fair? If I take an ambulance ride I have to pay for it. Why not stupid butt druggies?
