These are things people say about Xylazine that aren't settled fact — each one attributed to who's actually claiming it, so a claim never quietly passes as established just because it showed up in a document. Weigh it yourself.
Reported
"The combined effect of fentanyl, bromazolam, xylazine, and frequently methamphetamine or cocaine contributes to a longer and clinically messier post-naloxone period"
Unattributed assertion · stance: pro
Not yet independently weighed — one source's claim, unconfirmed elsewhere.

Reported
"Xylazine wounds are caused by xylazine-induced vasoconstriction and local tissue ischemia"
Unattributed assertion · stance: pro
The evidence on file mostly supports this, but it's still someone's claim, not a settled fact.
