The NJMMP requires that all medical marijuana that is sold in the state must be packaged in either 1/4 or 1/8 ounce units. The patient's particular MMJ health care provider will decide on the precise dosage; however, the maximum amount currently allowed to be possessed by New Jersey law is 3 ounces in 30 days. However, if a patient is terminally ill, they can possess an unlimited amount of medical marijuana.
