Please note that New York currently does not offer medical marijuana reciprocity. This means, that if you have a medical marijuana card in California or any other state, I am afraid it is not recognized in New York. You would need to have another consultation with a New York practitioner, provide a proof of residency and receive a photo ID card prior to visiting a New York dispensary.
Some states that will recognize out of state medical marijuana cards include Arizona, Nevada, Michigan and Maine. With that said, each state has their own set of rules and regulations, and they may vary by each dispensary or delivery service. Be sure to check the local laws prior to visiting to avoid any legal issues.
I hope this information helps! 🙂
