Chaz has been using medical marijuana to treat this disease because other very strong medications were unable to treat him properly.
To make it more medical-friendly, its active ingredient THC was synthesized in 1966, and finally approved by the U.S. Food and Drug Administration in 1985.
Marijuana can be used to treat glaucoma, which increases the pressure in the eyeball, injuring the optic nerve and causing loss of vision. According to National Eye Institute, marijuana lowers the pressure inside the eye,

Robert J. DeLorenzo, of Virginia Commonwealth University, gave marijuana extract and synthetic marijuana to epileptic rats. The drugs stopped the seizures in about 10 hours.
A 1999 a U.S. Government sponsored study by the Institute of Medicine uncovered the beneficial properties of marijuana in certain medical conditions such as nausea caused by chemotherapy, and wasting caused by AIDS. Since 1999, a number of studies have been done to show that smoked marijuana has pain reducing effects.
Marijuana maybe a better sleep aid than some other medications or even alcohol because the latter two may potentially have worse effects on sleep, though more research is needed on the topic.
The doctors who are recommending this medication say that the cannabidiol in the plant interacts with the brain cells to quiet the excessive activities in the brain that causes the seizures.
States that allow restricted use only include: Alabama, Georgia, Idaho, Iowa, Kentucky, Mississippi, Missouri, North Carolina,South Carolina, Tennessee, Texas, Virginia, Wisconsin and Wyoming.
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 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 are the side effects of medical marijuana?
“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.
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.

To take medical marijuana, you can:
Last year, the F.D.A. approved Epidiolex, a purified CBD extract, to treat rare seizure disorders in patients 2 years or older after three randomized, double-blind and placebo-controlled clinical trials with 516 patients that showed the drug, taken along with other medications, helped to reduce seizures. These types of studies are the gold standard in medicine, in which participants are divided by chance, and neither the subject nor the investigator knows which group is taking the placebo or the medication.
“It’s promising in a lot of different therapeutic avenues because it’s relatively safe,” said James MacKillop, co-director of McMaster University’s Michael G. DeGroote Center for Medicinal Cannabis Research in Hamilton, Ontario.
More than 60 percent of CBD users were taking it for anxiety, according to a survey of 5,000 people. Does it help?
Dr. Smita Das, chair of the American Psychiatric Association’s Council on Addiction Psychiatry’s cannabis work group, does not recommend CBD for anxiety, PTSD, sleep or depression. With patients turning to these to unproven products, she is worried that they may delay seeking appropriate mental health care: “I’m dually concerned with how exposure to CBD products can lead somebody into continuing to cannabis products.”
Some CBD products may contain unwanted surprises. Forensic toxicologists at Virginia Commonwealth University examined nine e-liquids advertised as being 100 percent natural CBD extracts. They found one with dextromethorphan, or DXM, used in over-the counter cough medications and considered addictive when abused; and four with a synthetic cannabinoid, sometimes called Spice, that can cause anxiety, psychosis, tachycardia and death, according to a study last year in Forensic Science International.
