Chronic heroin use may extend this window, causing the drug to be detectable in hair samples for longer than people who use heroin irregularly or infrequently. Therefore, detecting morphine or codeine in the body may be considered a sign of illicit heroin use. Heroin use can also be detected if a specific heroin metabolite, 6-monoacetylmorphine (6MAM), is found in a drug screening. Clinicians can find positive results for heroin use for up to one to three days on average, or up to 90 days with hair testing.

Generally, heroin is eliminated from the saliva within between 5 and 6 hours but saliva drug tests for heroin vary in their ability to capture someone’s drug use. Saliva tests have a shorter detection window, typically identifying THC for up to 24 hours after use, while blood tests can detect THC for up to 12 hours post-use. This is because blood tests are invasive and require someone who is trained to draw the blood. In addition, drugs leave the bloodstream more quickly than they leave the urine.

Instead, most drug tests for heroin look for substances that heroin breaks down to, including 6-MAM and morphine.
