A medical marijuana patient is suing his former employer, claiming the company terminated his refinery job after he used prescribed cannabis while off the clock.

The claim comes as New Jersey employers are changing their drug testing policies to keep pace with the new legal weed laws.

But the patient’s lawsuit argues that the medical cannabis law should have protected him even without legalization.

Jamal Campbell filed suit against Watco Companies and Watco Transloading LLC in U.S. District Court this April for violating the Jake Honig Compassionate Use Medical Cannabis Act and the state Law Against Discrimination.
