New York City announced this week that it plans to open “safe injection” sites for heroin addicts. If you’re unfamiliar with the concept and don’t want to read this explainer article we so kindly linked here for you, the basic idea comes down to harm reduction. Essentially, by providing users with sterile needles and emergency medical supervision (see: Naloxone), these sites could greatly decrease the amount of deaths and medical complications associated with illicit heroin use. European countries are less averse to the idea, citing study data which show these benefits as well as others like less public injecting and increased addiction treatment entry. That’s a harder sell in the US, where the dominant mindset is Just Say “No”.
