I'm wondering how he passed the drug test at the AFFEES station to get in the service to begin with. Fake piss?
Was it his "privilege" that stopped the cops from arresting him for drug possession?
For the first part, heroin metabolites clear from urine in only a few days, so if he was clean for even a few days ahead of entry/basic training he would have passed a whiz quiz. (And while I have not served, I think it would be difficult to use through basic without it being detected at some point.)
As far as the second part, most states and Arizona specifically provide some form of immunity from charges arising from a call to help an OD victim. Because so many folks were dying, it was seen as a way to encourage folks to call for help and not fear arrest (which as a long time FD/Paramedic in a particularly hard hit area, I agree with.) AZ Law
