What Is Harm Reduction — and What Does the Evidence Show?

Published August 3, 2026 · The Empower Brief

Harm reduction is a set of practical, evidence-based strategies designed to lower the health risks associated with drug use — not by requiring abstinence first, but by meeting people where they are. The core idea is straightforward: keeping someone alive and healthier today gives them a chance at recovery tomorrow. Decades of public health research back it up.

What harm reduction includes

Harm reduction is not a single program — it is an umbrella of tools and services. The most widely recognized include:

• Naloxone (Narcan) distribution. Putting the overdose-reversal medication in the hands of people who use drugs, their families, and community members. Naloxone is safe, now available without a prescription, and has no potential for misuse.
• Syringe services programs (SSPs). Community-based programs that provide sterile syringes and safe disposal of used ones for people who inject drugs, sharply reducing the spread of HIV and hepatitis C. They also connect participants to HIV and hepatitis testing, vaccinations, and referrals to substance use treatment.
• Fentanyl test strips (FTS). Low-cost paper strips that can detect fentanyl in an unknown drug supply in minutes. Because fentanyl is now found in many street drugs — including pills, cocaine, and methamphetamine — test strips give people information they can act on to reduce their risk.
• Drug checking services. Lab-based or point-of-care services that analyze street drugs and alert users and communities to dangerous adulterants like xylazine and nitazenes.
• Education and peer support. Training people who use drugs, their loved ones, and first responders in overdose recognition, safer use practices, and how to call for help.

What nearly 30 years of research shows

The evidence base for harm reduction — especially for syringe services programs — is robust. According to the CDC:

• Comprehensive SSPs are associated with an estimated 50% reduction in HIV and hepatitis C incidence among people who inject drugs.
• SSPs do not increase illegal drug use or crime in the communities where they operate.
• New users of SSPs are five times more likely to enter drug treatment than people who never use SSP services — meaning these programs are an active pathway into recovery, not an alternative to it.
• Nearly 30 years of research shows that comprehensive SSPs are safe, effective, and cost-saving compared to treating the HIV, hepatitis C, and bacterial infections that shared equipment causes.

NIDA's Director wrote in November 2024 that syringe services programs "are enormously effective" and remain critically underused, particularly in rural areas where injection drug use and overdose risk are high.

Harm reduction and treatment: a bridge, not a barrier

One of the most persistent misconceptions about harm reduction is that it discourages people from seeking treatment. Research consistently finds the opposite. Syringe services programs, naloxone distribution programs, and peer outreach all serve as pathways — points of contact where people who might never walk into a clinic can be connected to medications for opioid use disorder (such as buprenorphine and methadone), mental health services, and recovery support.

People in active addiction are not a monolith. Some are ready for abstinence-based treatment today; many are not yet there. Harm reduction keeps the door open by preserving life and building trust between service providers and the people they serve.

Fentanyl has raised the stakes for everyone

The contamination of the illicit drug supply with fentanyl has made harm reduction relevant far beyond people with opioid use disorder. Because fentanyl is now detected in cocaine, counterfeit prescription pills, and methamphetamine, a person who uses drugs recreationally and infrequently — and who has no opioid tolerance at all — faces the same overdose risk as a daily opioid user. That is why public health experts and organizations like Empower Next Project emphasize having naloxone on hand broadly, not just in high-risk settings.

Fentanyl test strips are similarly relevant for the whole community. Studies show that when people get a positive test result, many take protective steps: using with a friend present, having naloxone nearby, or discarding the supply. That is harm reduction in action.

How to find harm reduction services near you

Several free tools can help you locate services:

• SAMHSA's National Helpline (1-800-662-4357) — free, confidential, 24/7. Can help you find local naloxone, treatment, and harm reduction services.
• NASEN's SSP locator — the North American Syringe Exchange Network maintains a searchable map of syringe services programs across the U.S. at nasen.org.
• Your local health department — most county and city health departments can connect you to free naloxone, fentanyl test strips, and other services.
• 988 Suicide & Crisis Lifeline — call or text 988 for mental health and substance use crisis support around the clock.

At Empower Next Project, we believe every person deserves the chance to survive long enough to find recovery. Our Empower Next Breath program distributes naloxone and trains community members in overdose response. Contact us to learn more or to arrange a training in your community.
