While every state has laws dictating the use of medical marijuana, more than two thirds of U.S. states and the District of Columbia have actually legalized it for medical treatments and more are considering bills to do the same. Yet while many people are using marijuana, the FDA has only approved it for treatment of two rare and severe forms of epilepsy, Dravet syndrome and Lennox-Gastaut syndrome.Why hasn’t more research been done? One reason is that the U.S. Drug Enforcement Administration (DEA) considers marijuana a Schedule I drug, the same as heroin, LSD, and ecstasy, and likely to be abused and lacking in medical value. Because of that, researchers need a special license to study it, says Marcel Bonn-Miller, PhD, a substance abuse specialist at the University of Pennsylvania Perelman School of Medicine.
That may not change anytime soon. The DEA considered reclassifying marijuana as a Schedule II drug like Ritalin or oxycodone, but decided ito keep it as a Schedule I drug.
The agency did, however, agree to support additional research on marijuana and make the process easier for researchers.”Research is critically needed, because we have to be able to advise patients and doctors on the safe and effective use of cannabis,” Bonn-Miller says.
He shared some background on medical marijuana’s uses and potential side effects.
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.
What is medical marijuana used for?
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.
Has the FDA approved medical marijuana?
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. In addition, 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.
How do you take it?
To take medical marijuana, you can:
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.”
What are the side effects of medical marijuana?
Side effects that have been reported include:
Low blood pressure
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
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.
