When adjusted for age, the prevalence among workers in certain industries – such as food services, arts, and construction industry – saw significant decreases, which lead investigators to conclude younger employees would be a key target for more marijuana-related drug-use policies.
Ms. Smith and her colleagues recognized the population used may not be a full representation of all Colorado employees and that missing data regarding how often individuals used marijuana within 30 days could offer different considerations for workplace impairment.
Investigators also noted the data may have been influenced by self-reported bias or recording errors by survey takers.
Moving forward, Ms. Smith and her colleagues are interested in how this data might shift as more states conduct their own research and as marijuana policy changes.
This report was funded by the CDC, and investigators report no relevant financial disclosures.
