The study examines racial/ethnic differences in reports of workplace drug testing across various occupations in the U.S., finding significant disparities associated with race, age, gender, income, and occupation type. Researchers discovered that 48.2% of respondents reported drug testing at their workplaces, with specific associations for Black and Hispanic workers in certain job sectors. The findings highlight potential biases in drug testing practices and suggest the need for more equitable implementation across all workplaces.
