Where I live, the drug of choice is almost exclusively heroin. I am well versed in the treatment of heroin overdoses and the resources for those who use, as we have several per day on average. I've never dealt with a patient on bath salts, meth, crack, etc. , at least to my knowledge. I'm getting ready to relocate to a different region and i'm realizing I may have to educate myself on other presentations for other substances!
