The law allows testing for pre-employment, reasonable suspicion, post-accident, and random testing, with a mandatory 30-day prior written notice before beginning the drug testing program, and offers employees one opportunity to seek treatment for a drug or alcohol problem before the programs begins.
An employer may only test a prospective employee for marijuana use after a conditional offer of employment has been extended, unless otherwise required by law. An employer does not need to permit or accommodate the use, consumption, possession, transfer, display, transportation, sale, or growing of marijuana in the workplace or at any time during employment. An employer may deny a position based on a positive test for marijuana.
