Provides employer and employee protections pursuant to use of legalized cannabis items.

S 3603 protects New Jersey employees and job applicants from employment discrimination due to the legal use of cannabis. It prohibits employers from refusing to hire, firing, or taking adverse actions based solely on cannabis use, but allows drug testing for reasonable suspicion of impairment during work, visible intoxication, or after a work accident. Employers may use scientifically reliable testing methods (like blood, urine, or saliva) and require a physical evaluation by a certified expert to assess impairment, though pre-employment cannabis testing is banned. The bill also establishes certification standards for workplace experts who help detect impairment, but employers are not required to use these experts.
