Question about NY's med marijuana law?

[edhopper]

The restrictive NY State med marijuana law limits the use to only certain illnesses.

The Medical Marijuana Program will make medical marijuana accessible to patients with conditions including cancer, HIV/AIDS, Lou Gehrig's disease (ALS), Parkinson's disease, multiple sclerosis, damage to the nervous tissue of the spinal cord with objective neurological indication of intractable spasticity, epilepsy, inflammatory bowel disease, neuropathies and Huntington's disease. The law includes these conditions when there is a clinical association with or complication of the condition resulting in cachexia or wasting syndrome, severe or chronic pain, severe nausea, seizures; or severe or persistent muscle spasms. Acting State Health Commissioner Dr. Howard Zucker is also exploring mechanisms that may accelerate access to medical marijuana for children suffering from epilepsy. The Health Commissioner may expand the list of eligible conditions for which medical marijuana certifications may be issued by practitioners.

Under the program, practitioners will be required to complete a training course and register with DOH to issue certifications to their patients for medical marijuana. Practitioners must certify that their patients have a serious condition and the patients are likely to receive therapeutic or palliative benefits from the use of medical marijuana for the serious condition in order to issue the certification. This process will ensure that medical marijuana is available only to patients with serious conditions who will benefit from the treatment.

I accept that they can restrict the form of drug and who can dispense it. But can they really say what Doctors can prescribe it for. Many drugs are prescribe for conditions other than their designated purpose? They can regulate and restrict it, but can they legal tell a Doctor what condition they can use it for. Is this true of any other drug? And can this be challenged in court?
