The Substance Abuse and Mental Health Services Administration (SAMHSA) is proposing a new rule that would allow federal agencies to use sweat, saliva and hair in federal drug testing programs that now only test urine. The proposal would also allow selected specimen testing at the time and place it is collected.
The proposal is based on scientific advances that will allow use of hair, saliva and sweat specimens to be used with the same level of confidence that has been applied to the use of urine.
