Workplace Drug Testing Laws in Tennessee

The following information is based on the provisions outlined in the Tennessee voluntary law for a Drug-Free Workplace – T.C.A. 50-6-418, 50-9-100 et. seq., and 50-6-110.

In the state of Tennessee, many employers adopt a drug-free workplace program to receive a discount on their workers' compensation insurance premiums. Employers who adopt this program are required to follow the notice, education, and procedural requirements outlined in the program guidelines. This includes the requirement to notify all employees that refraining from working while under the influence of drugs or alcohol is a condition of employment.

Per the workplace drug testing laws in Tennessee, if an injured employee refuses to submit to a drug and alcohol test, he or she will forfeit eligibility for workers' compensation medical and indemnity benefits.

The following information does not apply to DOT-regulated drug testing. Government employers who fall under provisions of the DOT should conduct further research to ensure compliance with relevant employment drug testing laws.
