The first step of qualifying for medical marijuana in the state of New York is determining whether you have one of the conditions deemed treatable by cannabis under state law. Conditions such as cancer, multiple sclerosis, Parkinson’s, ALS, and post-traumatic stress disorder can qualify as well as similar conditions that cause chronic spasms, pain, seizures, or an overall reduction in quality of life. If you have one of these types of conditions, you should schedule an appointment with an in-person or online doctor to take the next step toward qualification. This doctor will go through your health records to verify your condition and find out more about your symptoms and previous attempts at treatment. If the doctor believes you would make a good medical cannabis patient, he or she will issue a recommendation so you can apply for a registration card with the New York Department of Health. If your application is approved, you will receive your registration card in the mail within seven business days. Without this registration card, you will not be able to legally purchase cannabis in the state of New York.
