Heroin-Assisted Treatment

Fact Sheet June 11, 2023

What is Heroin-Assisted Treatment (HAT)?

Heroin-assisted treatment (HAT) refers to the prescription of pharmaceutical heroin (diacetylmorphine) to people with severe opioid use disorders who have not responded well to more traditional forms of treatment like methadone or buprenorphine.

Typically, clients are provided injectable or inhalable heroin 2-3 times per day by prescription, and they consume it on-site in a medically-supervised clinic setting. Some of these programs also provide access to hydromorphone as an option to patients. In clinical research trials, participants preferred  diacetylmorphine or hydromorphone equally.

HAT provides legal access to pharmaceutical heroin to prevent patients from buying it on the illicit market where it may be adulterated, or mixed, with unknown drugs or substances. Patients are given access to harm reduction interventions, connections with substance use disorder treatment and medical services, and social supports such as housing assistance.
