Control Policy (ONDCP) currently defines harm reduction as a public health approach designed to advance policies and programs for PWUD, based on the principles of Care/Support/Connect/Respect. For additional background on this, please see text box on Defining Harm Reduction Principles, page 32. A comprehensive harm reduction program consists of initiatives and measures aimed at mitigating the adverse public health and social consequences of drug use, which are an integral part of a continuum of care. The programs must be evidence-based and person-centered. Policy and program changes are required to reach PWUD—central to this effort must be increased adoption of a harm reduction approach. As was highlighted by the bipartisan Commission on Combating Synthetic Opioid Trafficking, harm reduction programs not only offer protection from elevated risks posed by today’s drug supply, but often serve as points of entry for long-term treatment.116 Harm reduction programs build trust and engagement between outreach workers, including peers with lived experience, and PWUD. These individuals, including people experiencing unstable housing or homelessness, are at high risk of overdose and of contracting or transmitting infectious diseases, such as hepatitis B, hepatitis C or HIV, and can benefit from harm reduction services to improve their health, build linkages to physical and mental health services, and provide low-threshold, flexible opportunities to initiate substance use disorder treatment. Not all of those who use drugs have SUD, which is a chronic medical disease that is driven by a host of biological and environmental factors. However, for many PWUD, whether they have been formally diagnosed with an SUD or not, regular substance use is difficult to stop, even when negative consequences mount. These individuals are often caught between substance use that both fuels and impedes their daily life and a health care system that lacks the engagement capacity to meet them where they are and fails to engage them in health and social services. According to the 2020 National Survey on Drug Use and Health (NSDUH), the vast majority of the over 40 million living in the United States who need treatment for SUD are not currently receiving addiction treatment services.117 This means that while some with SUD, as well as the larger group of PWUD, seek and receive care, there are far more who have not yet received the support they need. The reason why most of those with SUD have not received treatment is that they did not seek it. Harm reduction programs have the potential to proactively reach out to these individuals and offer them the level of care they are ready to accept. Many people with SUD also face stigma from public and health care professionals which may result in hesitation to seek treatment.118 PWUD are at increased risk of fatal overdose, particularly from knowingly or unknowingly consuming substances containing illicitly manufactured fentanyl and its analogues. Early interventions are necessary to provide harm reduction services and offer treatment and health services to prevent loss of life. Harm reduction programs enable PWUD to access services which reduce overdose risk and enhance health and safety. Trust developed between harm reduction outreach workers and PWUD often facilitates a range of potentially life-saving options including adequate supplies of « « « « « « NATIONAL DRUG CONTROL STRATEGY 31 naloxone, sterile injection supplies such as syringes, and fentanyl test strips (FTS); linkage to evidence-based treatment, including medication for opioid use disorder (MOUD); screening for HIV and Hepatitis C infection; and access to health and social services that address social determinants. Research shows harm reduction programs produce results. For example: • People who use heroin and others who inject drugs who regularly utilize a syringe services program (SSP)—which provide sterile syringes and other health and social services—are five times more likely to initiate SUD treatment, compared with those who have never used an SSP.119 • SSPs can be effective platforms to motivate people with opioid use disorder (OUD) to enroll in substance use treatment and, over time, to reduce drug use and number of drug injections—according to a local study. 120 • Expanded buprenorphine treatment and linkage to social services have been identified as major contributors to the success of a Philadelphia SSP.121 • SSPs have also been shown to substantially reduce HIV and Hepatitis C infection among people who inject drugs.122 • In addition to saving lives and improving health, harm reduction programs that include providing clean syringes and medications for OUD—are highly cost-effective, both when these services are provided separately and even more so when combined.123 • Using FTS and receiving a positive test result has been associated with changes in drug use behavior and perceptions of the risks of an overdose. 124 • Analysis also indicates that distribution of naloxone to counter the effects of an opioid overdose not only saves lives but also produces a significant return on investment.125 We must continue to conduct research on the optimal ways to deliver, expand, and continuously improve the health of PWUD, especially through supporting and
