Marijuana use can prevent epileptic seizures, a 2003 study showed.
Robert J. DeLorenzo, of Virginia Commonwealth University, gave marijuana extract and synthetic marijuana to epileptic rats. The drugs rid the rats of the seizures for about 10 hours. Cannabinoids like the active ingredients in marijuana, tetrahydrocannabinol (also known as THC), control seizures by binding to the brain cells responsible for controlling excitability and regulating relaxation.
Marijuana may help prevent cancer from spreading, researchers at California Pacific Medical Center in San Francisco reported in 2007.
Cannabidiol stops cancer by turning off a gene called Id-1, the study, published in the journal Molecular Cancer Therapeutics, found. Cancer cells make more copies of this gene than non-cancerous cells, and it helps them spread through the body.
The researchers studied breast cancer cells in the lab that had high expression levels of Id-1 and treated them with cannabidiol. After treatment the cells had decreased Id-1 expression and were less aggressive spreaders.
It may decrease anxiety.
Medical marijuana users claim the drug helps relieve pain and suppress nausea — the two main reasons it’s often used to relieve the side effects of chemotherapy.
THC slows the progression of Alzheimer’s disease.
Marijuana may be able to slow the progression of Alzheimer’s disease, a study led by Kim Janda of the Scripps Research Institute suggests.
The 2006 study, published in the journal Molecular Pharmaceutics, found that THC, the active chemical in marijuana, slows the formation of amyloid plaques by blocking the enzyme in the brain that makes them. These plaques are what kill brain cells and cause Alzheimer’s.
