Perhaps you read about the NIOSH study published in late August that found construction workers die of drug overdoses (not while on the job) at a rate six times higher than the general work population. Heroin was the main killer, followed by prescription opioids.
Of course construction workers face risks every day. A fall from scaffolding or bad knees from years of cement work can lead to prescriptions for opioid pain medication, which in turn can lead workers down a rabbit hole into pain pill addiction, and then to cheap heroin, usually laced with fentanyl, an even more powerful synthetic opioid.
