Doctors still think the Naloxone in Suboxone actually prevents people from "abusing it". The patent holder fed them a bunch of bullshit decades ago about how it causes precipitated withdrawal if you snort or IV it instead of using the prescribed sublingual RoA.

But despite the universal experience of people who have snorted and IV'd it being that the Naloxone may as well be inactive due to it having a significantly lower mu-opioid receptor binding affinity than Buprenorphine, doctors still to this day insist on prescribing Suboxone instead of plain Buprenorphine, often at double the cost to the patient.
