Drug Checking Services
Tapestry is part of a growing movement in Massachusetts to advance community drug-checking initiatives.
Our drug checking team tests samples and shares results directly with the community. Results are fully confidential and available within 1 week: in person, by phone, or online at info.streetcheck.org/drug-results.
We use fentanyl, xylazine, benzodiazepine, medetomidine, and nitazene test strips, plus FTIR technology to analyze samples. Free fentanyl test strips are also available to take home at all Harm Reduction locations.
