JANUARY 19, 2019 – During the first stage of the study, each participant received 10 fentanyl test strips, which work like an over-the-counter pregnancy test. A single-use strip is dipped into water containing a bit of drug residue (before drug use) or urine (after drug use) and either one or two red lines quickly appear—one line means the liquid contains fentanyl, and two lines means the test did not detect the drug. The strips cost about $1 each and are beginning to be distributed by harm reduction organizations in the United States.
