Approaching a van that distributes supplies for safer drug use in Greenfield, Massachusetts, a man named Kyle noticed an alert about xylazine.
“Xylazine?” he asked, sounding out the unfamiliar word. “Tell me more.”
A street-outreach team from Tapestry Health Systems delivered what’s becoming a routine warning. Xylazine is an animal tranquilizer. It’s not approved for humans but is showing up in about half the drug samples that Tapestry Health tests in the rolling hills of western Massachusetts. It’s appearing mostly in the illegal fentanyl supply but also in cocaine.
