Just read this piece on Nabarun Dasgupta and his street drug analysis lab.
I know Nab a bit in real life, and he’s exactly what you’d hope. Brilliant, funny, fun to hang out with, and grounded in the work.

A lot of the conversations happening right now about xylazine, medetomidine, and other adulterants trace back to this kind of work. This is where that information comes from.
He’s also been behind efforts, along with some other brilliant folks, that have distributed millions of doses of low-cost naloxone nationally, which has saved a lot of lives.
If you're interested in how we know what’s actually in the current drug supply, this article is a great use of your time.
