Fuquan Johnson and Michael K. Williams died of fentanyl overdoses this week and there have been a few seizures of shipments of fentanyl (which the news is apparently sometimes measuring not by weight but by how many people it can kill????? very irresponsible, news organizations)
But part of what people are missing with these warnings is that almost nobody who is overdosing on fentanyl is taking fentanyl intentionally; Fuquan Johnson overdosed after taking cocaine laced with fentanyl.
So here is how to use fentanyl test strips to check for fentanyl.
And here is a fifty-pack of fentanyl test strips for fifty dollars. They sell those in smaller packs too, but if you know people who use drugs that are likely to be contaminated with fentanyl you may want to let them know about this. You may want to see about doing a group buy of test strips if you know several people likely to benefit from them.
If you have a local harm reduction program - a needle exchange, or a safe injection site, you may want to contact them and see if you can donate or volunteer, they're probably getting hit hard right now.
