It's just that when something is widespread enough you can actually study other effects it has. Sort of like how psilocybin and weed had all these other effects but we couldn't study them till they got a little less criminalized. All sorts of shit does stuff, but we grandfathered in substances and froze everything for a while. Then COVID came along and a bunch of people started doing telemedicine and before you know it compounding pharmacies were handing out GLP-1RAs as a substitute for the phentermine they were passing out. Not scheduled, absolutely effective, great stuff.

Then with all that use in the wild you could rock and roll. Only problem is that off-label use like me with my retatrutide makes some population studies less effective than before.
