Harm reduction is an approach that promotes health in a way that meets people where they are at, accepting that not everyone is ready or capable of stopping their substance use at a given time. Instead of making judgments about where individuals suffering from addiction should be with regards to their health and behavior, harm reduction focuses on promoting evidence-based methods for reducing associated health risks in the current moment (e.g., preventing HIV transmission).

The defining features of harm reduction include a focus on the prevention of harm, rather than on the prevention of substance use itself. Harm reduction initiatives run the gamut from medical care and disease prevention, to education and linkage to addiction treatment. (Recoveryanswers.org)
