**Opioid Rules of Thumb Are Sticky—Even When the Evidence Moves On.** From how quickly dependence risk starts to whether the newest non-opioid really replaces an opioid, a lot of advice is still…
Y- you know, Steve, opioids are, you know, one of the topics where two things can be true at once.
You know, they could be essential for managing pain, but they can carry serious risks if we get casual with the details.
The problem is that the casual details become clinic hallway wisdom, like short courses are always safe, higher naloxone is automatically better, and even conversion tables are exact.
Coding works for cough, like the list goes on [laughs] and, and it sounds tidy, but the evidence is messier.
And today's claims cover both sides, avoiding unnecessary opioid harm, but also making sure patients who need pain treatment, especially patients with opioid use disorder, aren't dismissed or undertreated.
It's opioids require nuance, which is the least catchy slogan ever, but clinically very useful.
Let's get into the evidence carefully because this is one place where shortcuts can cause real problems.
Let's start with a claim that challenges something a lot of clinicians have probably thought at some point.
What harm can that do? So the claim is that dependence risk can increase soon after initiating opioids.
... physical dependence occurs with repeated use, you know, causing the neurons in the brain to adapt, so they only function normally when a patient is taking the drug.
And let's not confuse that with addiction or opioid use disorder, which is a chronic disease where patients develop uncontrollable drug-seeking behavior despite negative consequences, and it involves long-lasting changes in the brain.
