Wyoming drug testing laws for employers

Wyoming has no general workplace drug testing law, so private employers set their own rules. The state workers' comp fund gives up to a 10% discount for an approved drug and alcohol testing program. Marijuana is not legal for medical or adult use, and Wyoming's old hemp-extract law was repealed in 2019.
