New Jersey Statutes Title 24. Food and Drugs 24 § 6I-6.1

b. (1) If an employer has a drug testing policy and an employee or job applicant tests positive for cannabis, the employer shall offer the employee or job applicant an opportunity to present a legitimate medical explanation for the positive test result, and shall provide written notice of the right to explain to the employee or job applicant.

(2) Within three working days after receiving notice pursuant to paragraph (1) of this subsection, the employee or job applicant may submit information to the employer to explain the positive test result, or may request a confirmatory retest of the original sample at the employee's or job applicant's own expense. As part of an employee's or job applicant's explanation for the positive test result, the employee or job applicant may present an authorization for medical cannabis issued by a health care practitioner, proof of registration with the commission, or both.

(1) restrict an employer's ability to prohibit, or take adverse employment action for, the possession or use of intoxicating substances during work hours or on the premises of the workplace outside of work hours; or

(2) require an employer to commit any act that would cause the employer to be in violation of federal law, that would result in a loss of a licensing-related benefit pursuant to federal law, or that would result in the loss of a federal contract or federal funding.
