2020 was famously a period where the pandemic and the opioid crisis were causing death and despair all over the country, but somehow that became the excuse for backpedaling on decriminalization in Oregon before there could have even been effects to study, not to mention before there was time to study those effects. They even recriminalized drugs that have never been associated with overdose or addiction, like psychedelics. Basically, they did the bare minimum necessary to be able to say "we tried it and it didn't work" with a straight face. Don't fall for it.
