A newly proposed federal rule would expand workplace drug testing programs by allowing certain employers to collect and analyze samples of workers’ hair, a move critics say would lead to disproportionate job-related punishments for people of color.
Federal agencies can already test workers’ urine and saliva, which provide evidence of more recent drug use, but “hair testing potentially offers several benefits when compared to urine, including directly observed collections, ease of transport and storage, increased specimen stability, and a longer window of drug detection,” the Substance Abuse and Mental Health Services Administration (SAMHSA) argued in a notice of proposed rulemaking published in the Federal Register on Thursday.
If adopted, the change would affect thousands of government employees as well as private workers in certain federally regulated industries such as those who work in transportation or at nuclear power plants.
Drug reform advocates are skeptical about the move.
“It’s shameful that these harmful federal drug testing guidelines are even being considered again,” Rep. Barbara Lee (D-CA), co-chair of the Congressional Cannabis Caucus, told Marijuana Moment. “Not only is hair follicle testing discriminatory against people of color due to its sensitivity to melanin and darker hair, it gives no indication of someone being impaired on the job. This just goes to show how far behind the federal government is on cannabis policy.”
Paul Armentano, deputy director for the advocacy group NORML, said it is “mind-boggling that, in 2020, SAMHSA is considering expanding federal drug testing guidelines.”
“Hair follicle testing is highly problematic,” Armentano said. “A positive test, even when confirmed, provides neither evidence of behavioral impairment nor recent drug exposure. Moreover, the sensitivity and accuracy of the test is highly variable.”
Because hair exists outside a person’s body, for example, it’s more vulnerable to contamination—including secondhand smoke and other chemicals—than other sample
