The state of Arizona lists the following conditions eligible for medical marijuana:

• Cancer
• Glaucoma
• Human Immunodeficiency Virus (HIV)
• Acquired Immune Deficiency Syndrome (AIDS)
• Hepatitis C
• Amyotrophic Lateral Sclerosis (ALS)
• Crohn’s disease
• Agitation of Alzheimer’s disease
• A chronic or debilitating disease or medical condition or the treatment for a chronic or debilitating disease or medical condition that causes:
• Cachexia or wasting syndrome;
• Severe and chronic pain;
• Severe nausea;
• Seizures, including those characteristic of epilepsy;
• Severe or persistent muscle spasms, including those characteristic of multiple sclerosis

Medical records and diagnosis are necessary to document the condition. Bluntly (pun intended) you can’t walk in and get a card for no reason. The laws are different than California. While research shows marijuana can benefit other conditions, these are what the state deems eligible.

The human body has cannabinoid receptors just as it has opiate receptors, hence, the effectiveness of opiates and cannabis. The human body produces both of these substances naturally. Interesting note is that breast milk contains cannabinoids that is part of the theory of why breast fed babies have stronger immune systems (and babies look a bit loopy after feeding). May medications to treat HIV are based on cannabinoid receptors.

Like any pharmaceutical personal responsibility is key. Having a card does not entitle you to drive or work while impaired.
