NJ S3452

Prohibits employers from taking adverse employment action against employees who are registered medical cannabis patients based solely on their cardholder status or a positive cannabis drug test.

Employers may only take action if they establish by a preponderance of evidence that medical cannabis use has impaired the employee's ability to perform job duties, demonstrated through specific articulable symptoms while working.

Requires employers with drug testing policies to provide written notice and offer employees or job applicants who test positive for cannabis three working days to explain the result or request a confirmatory retest at their own expense.

Allows employees to present a healthcare practitioner's recommendation or registry identification card as explanation for positive test results.

Preserves employer rights to prohibit cannabis possession or use during work hours and does not require employers to violate federal law or risk losing federal contracts or funding.
