Americans who worked in construction and extraction, food preparation, personal care, service and transportation and material moving occupations were the most likely to die from drug overdoses during the year of the COVID-19 pandemic, according to new data released Tuesday from the Center for Disease Control’s National Center for Health Statistics.

Researchers from the CDC analyzed deaths caused by drug overdoses of working-age United States residents in 2020 in 46 states and New York City, focusing on industries and occupations.

The findings come as the CDC reports, “This trend intensified during the COVID-19 pandemic; the U.S. drug overdose death rate in 2021 was 50% higher than in 2019.”

The top industry groups to be affected by drug overdoses in 2020 were “construction, accommodation and food services, other services (except public administration), management, administrative, waste services, mining, arts, entertainment, recreation and transportation and warehousing.”

And fishermen, sailors, roofers, drywall workers, ceiling tile installers, and conservation personnel were among the “individual census occupations and industries” most likely to be affected that year, the report found.

The report says that occupations or industries with the highest drug overdose rates were more likely to be ones where injured workers use prescription opioids due to physical injuries on the job.

Construction workers were four times more likely to die from drug overdoses than the whole population, for example, according to the research.
