What I learned today

Learning more about fentanyl and other drugs. Went to a seminar given by a pharmacist whose practice is mostly with drug users and the mentally ill.

One reason there are so many fentanyl deaths is it's very potent - a small amount (like a few grains of powder) can kill. I had been hearing weird stuff like dealers were putting it in other products on purpose, but why kill your customers? And sell them something that would have vastly different effects than what they wanted if they wanted a stimulant like cocaine rather than a sedative/analgesic like opioids? He said it was because low-level dealers might have been cutting up a batch of fentanyl, or the even more potent carfentanil, on a table one day, and been cutting up a batch of cocaine on the same table the next day, and the small amount of fentanyl that remained behind got mixed up in it - the same thing could even happen with marijuana.

I also learned about something called "Lean", a drink with codeine or hydrocodone mixed in to some kind of juice or soft drink, sometimes with a bunch of Skittles mixed in to cover the bitter taste.
