WedMD: Medical Marijuana FAQ

What is medical marijuana?

Medical marijuana uses the marijuana plant or chemicals in it to treat diseases or conditions. It's basically the same product as recreational marijuana, but it's taken for medical purposes. 

The marijuana plant contains more than 100 different chemicals called cannabinoids. Each one has a different effect on the body. Delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the main chemicals used in medicine. THC also produces the "high" people feel when they smoke marijuana or eat foods containing it.

Medical Marijuana: What Does It Treat?

Medical marijuana is used to treat a number of different conditions, including: 

But it’s not yet proven to help many of these conditions, with a few exceptions, Bonn-Miller says. 

"The greatest amount of evidence for the therapeutic effects of cannabis relate to its ability to reduce chronic pain, nausea and vomiting due to chemotherapy, and spasticity [tight or stiff muscles] from MS," Bonn-Miller says. 

How does it help? 

Cannabinoids -- the active chemicals in medical marijuana -- are similar to chemicals the body makes that are involved in appetite, memory, movement, and pain. 

Research suggests cannabinoids might: 
  • Reduce anxiety
  • Reduce inflammation and relieve pain 
  • Control nausea and vomiting caused by cancer chemotherapy
  • Kill cancer cells and slow tumor growth 
  • Relax tight muscles in people with MS
  • Stimulate appetite and improve weight gain in people with cancer and AIDS
  • Can medical marijuana help with seizure disorders? 
Medical marijuana received a lot of attention a few years ago when parents said that a special form of the drug helped control seizures in their children. The FDA recently approved Epidiolex, which is made from CBD, as a therapy for people with very severe or hard-to-treat seizures. In studies, some people had a dramatic drop in seizures after taking this drug. 

Which states allow medical marijuana? 

Medical marijuana is legal in 33 states and the District of Columbia: 
District of Columbia 
New Hampshire 
New Jersey 
New Mexico 
New York 
North Dakota 
Rhode Island 
West Virginia 

States that allow restricted use only include: Alabama, Georgia, Iowa, Kentucky, Mississippi, Missouri, North Carolina,South Carolina, Virginia, Wisconsin and Wyoming. 
How do you get medical marijuana? 

To get medical marijuana, you need a written recommendation from a licensed doctor in states where that is legal. (Not every doctor is willing to recommend medical marijuana for their patients.) You must have a condition that qualifies for medical marijuana use. Each state has its own list of qualifying conditions. Your state may also require you to get a medical marijuana ID card. Once you have that card, you can buy medical marijuana at a store called a dispensary. 
How do you take it? 

To take medical marijuana, you can: 
  • Smoke it 
  • Inhale it through a device called a vaporizer that turns it into a mist 
  • Eat it -- for example, in a brownie or lollipop 
  • Apply it to your skin in a lotion, spray, oil, or cream 
  • Place a few drops of a liquid under your tongue

How you take it is up to you. Each method works differently in your body. "If you smoke or vaporize cannabis, you feel the effects very quickly," Bonn-Miller says. "If you eat it, it takes significantly longer. It can take 1 to 2 hours to experience the effects from edible products." 

Has the FDA approved medical marijuana? 

The FDA has approved two man-made cannabinoid medicines -- dronabinol (Marinol, Syndros) and nabilone (Cesamet) -- to treat nausea and vomiting from chemotherapy. The cannabidiol Epidiolex was approved in 2018 for treating seizures associated with two rare and severe forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome. 

What are the side effects of medical marijuana? 

Side effects that have been reported include: 
The drug can also affect judgment and coordination, which could lead to accidents and injuries. When used during the teenage years when the brain is still developing, marijuana might affect IQ and mental function.
