Yes, but, there are no recreational dispensaries in NYC as far as I know and there are none within Jersey City. The only ones I know of are Rise in Bloomfield, Apothecarium in Maplewood, and Ascend in Rochelle park, they’re all about 30-40 mins by car from JC. Just need to be 21 or older and technically you can only smoke in your private residence, not in hotels or most rental units.
