I dont really care all that much either way for people who want to do drugs. They should be legalized, licensed and produced safely, with addict treatment going to medical and mental health services, not the police.
The main concern with fentanyl is that people who want to do drugs probably don’t want to do fentanyl; they’re probably seeking heroin, and getting fentanyl that they’ve been lied to about.
But the solution to that isn’t to continue the failed policy of prohibition, it’s legalization and regulation, so fuck the dealers who lie about what they’re selling, but also yes, fuck the police.
