Harm reduction aims to reduce the negative consequences of substance use and offers an alternative to abstinence-only intervention. Rooted in activism by people who use drugs, many harm reductionists advocate for safe drug supply and decriminalization (see Bonn). An expanded understanding of harm reduction as a movement encompasses notions of collective healing, unity across geographies, and resistance to all forms of systemic oppression (Oyola-Santiago; Ansloos and Gardner).
