Look at the stats, fentanyl has always been rarely prescribed and even more rarely prescribed compared to other opioids. The fentanyl crisis is a crisis of economics: there is less profit to be made in creating, smuggling and selling other opioids compared to fentanyl.
If you want to be accurate, doctors prescribed non-fentanyl opioids in situations where they weren't needed, often illegally, when those prescriptions ran out, that caused a heroin crisis. That heroin crisis became a fentanyl crisis when drug dealers stopped selling heroin in favor of the cheaper and much stronger fentanyl.
Easy to say when you aren't facing the threat of bias intimidation or hate crime by recently emboldened bigots, things that actually happen unlike the caravan paranoia.
