Washington employers soon will be restricted from rejecting most job applicants based on their off-duty cannabis use. Effective Jan. 1, 2024, a new law will mean no one can be rejected because of marijuana use outside of work and away from the workplace, or because of pre-employment drug tests that show the use of marijuana. Washington employers can use pre-employment drug tests to screen for other recreational drugs and the new law does not apply to applicants for certain narrowly defined positions.
