>> Researchers have pondered what could have caused this sudden turnaround, pointing to the end of the covid-19 pandemic or a rise in drug treatment. A new article, published in Science on January 8th, suggests, instead, that a supply shock drove the decrease.
The supply shock sounds right.
I was volunteering at a state run institution, who had an addiction data science team, at the peak of the opioid crisis. I was developing ml models to predict patient dropout early in a 32 week program. The data and funding for such research was very scarce and it didn't go anywhere.
Treatment for opioid use disorder with medication is highly effective for 50% - 90% who respond well to treatment. The problem with the bottom 50% was early dropout, due to the lack of dissemination of proper treatment protocols and stigma attached to medication for treatment (methadone). I stopped following the work, I became too sensitive, it was pretty depressing.
The pandemic coupled with the increase in illicit fentanyl was just tragic in what it did to people. I remember reading the DEA research, where the precursor for fentanyl came from china and was manufactured and distributed from mexico. Mexico was also manufacturing high quality meth and displaced most of the meth labs in america, coming with increases in meth overdose during the same period. The fentanyl was so cheap compared to traditional heroin manufacturing.
I'm glad the supply seems to have dried up. It was nuts, what was going on a few years ago.
