The addiction rates of legally prescribed opioids is surprisingly small. The problem was pill mills and diversion to the secondary market. People who are looking to get high tend to have a very large chance of becoming addicted. If anything the pendulum has cut people on both sides. First they had pill mills and pills flooded the streets. Then they basically stopped almost all prescriptions and then you had everyone all the sudden scrambling for pills, real pills evaporated quickly. Fentanly 30s started flooding the streets and then just fentanyl powder sold as H, because why pay more for a pill if it's the same stuff.
