According to the current state laws, you must have at least one disease on a specific list of conditions and this must be diagnosed by a real doctor who recommends cannabis as an appropriate medication.
The doctor provides the patients with a written instruction that will alleviate the symptoms of their condition. Patients then have several options open to them depending on which state's laws they live under. You can also look for the legal weed dispensary via http://www.barneysdelivery.com/

The first option in many states is to simply take the letter of recommendation from your doctor to a medical marijuana dispensary. They will most likely keep a copy of your letter on file and then you can purchase your prescription pot from this dispensary from that point on.
The next option is for you to take the letter from your doctor and send it in with certain health department forms to your state government. Your state's health department will then send you a medical card. This card can then be used at various dispensaries within your state.
Most states also provide a third option for patients. You can acquire your doctor's letter of recommendation and then send it to the state's health department with the necessary forms. This third option, however, requires you to request a medical card in order for you to grow your own medicinal cannabis. The laws in this area not only vary by state, but also by county in some cases.
A qualified patient can be in possession of anywhere from eight ounces of them to several pounds and they can grow and maintain from six to fifty plants of varying maturity depending on which county of the state they live in.
