The short answer is “yes,” but the rules regarding out-of-state medical marijuana cards in New Jersey are complex. According to the state’s Jake Honig Compassionate Use Medical Cannabis Act that took effect in July 2019, people who are medical marijuana patients in other states can be qualified as patients in New Jersey for up to six months.
New Jersey now has “reciprocity” for out-of-state medical marijuana patients who have the same qualifications as New Jersey state resident MMJ patients.
Reciprocity lasts for up to six months and allows you to legally possess and use medical marijuana.
You can’t legally buy medical marijuana in New Jersey with an out-of-state medical card until you have been authorized by a New Jersey medical marijuana physician.
To be able to visit a licensed dispensary in New Jersey and purchase marijuana with an out-of-state medical marijuana card, you need to receive authorization from a New Jersey medical practitioner that states that you qualify for New Jersey’s medical marijuana program.
You will go through the same process as state residents who apply for the medical marijuana program. Once you receive physician approval, you will be entered into the state’s medical marijuana program registry. You’ll receive a medical marijuana card that is good for up to six months or the amount of time you will be visiting New Jersey, whichever is shorter. If you’ll be staying longer than six months, you should apply for a medical marijuana card as a regular resident. [Source]
