Yes, op, some lie, some buy fake crap, some buy on the black market, for many drugs this has always been the case, presricption painkillers is a key example. Drug abuse is not some new thing, it’s always been thus. If there is a drug that gives a desired outcome for someone, there is always someone who will lie, cheat, or buy illegally to get their hands on it.
however the overwhelming majority don’t lie, as they don’t need to. And you can’t have a situation where it becomes too difficult for those in need to get them, due to the idiots who lie or buy crap. Same for all drugs people abuse. You make it too difficult and the black market explodes, and you deny people life changing and saving medication as the wait is so long due to logistics.
So so many people are eligible for these drugs, you need to find a way to prescribe that works, and accept the risk that yes some people who aren’t eligible will do whatever it takes to get them,
doesn’t matter if it’s diazepam or mounjaro , Christ some folks even go round pharmacies buying multiples of cold medicine so they can abuse codeine.
there is nothing new here. If a drug exists that will give someone whay they want, and they can’t get it legitimately then some will lie, cheat, buy illegally and abuse it.
