New Mexico drug testing laws for employers

New Mexico has no general drug testing statute for private employers. Adult-use cannabis is legal, and employers may adopt a written zero-tolerance cannabis policy that allows discipline for any THC on a test. Medical cannabis patients are protected from adverse action, except in jobs the employer deems safety-sensitive.
