Legislation introduced Monday in Washington state would forbid employers from refusing to hire workers who test positive for marijuana.

H.B. 2740, sponsored by Democratic Reps. Shelley Kolba, Nicole Macri and Monica Stonier, would make it unlawful for an employer to refuse to hire a prospective employee for legally using mairjuana because he or she tested positive in a drug screen.

The bill contains several exceptions, however. The law would not apply for individuals in safety sensitive positions, such as firefighters, emergency medical technicians, or jobs involving the operation of motor vehicles that, under federal or state law, require employees to submit to screening tests. Employers who would lose a monetary or licensing-related benefit under federal law, or who must maintain drug-free workplaces due to a federal contract, would also be exempted from law.

The bill has been referred to the House Committee on Labor & Workplace Standards.
