Marijuana has been known to help with the following medical symptoms

Pain Relief — Research has shown that using marijuana may be helpful in managing neuropathic pain. A 2001 paper found that cannabis used at a concentration of 9.4% THC moderately reduced pain and improved sleep, with little side-effects.


Nausea — A number of studies have been done on the benefits of taking marijuana to help reduce vomiting and nausea in chemotherapy patients. The researchers found out that the cannabinoids were better than the active control or the placebo at reducing vomiting and nausea. THC is also well documented to increase appetite.


Glaucoma — Marijuana has been used to treat and prevent the eye disease glaucoma, which increases pressure in the eyeball, injuring the optic nerve and causing vision loss. Studies have shown Cannabinoids effectively lower intraocular pressure (IOP), likely by boosting ocular blood flow through their vasorelaxant properties.


Seizures — Small clinical studies suggest that CBD, a non-psychoactive compound of cannabis, could potentially be helpful in preventing seizures. For more information on Epilepsy and Cannabis please visit


Dravet’s Syndrome — is a syndrome which causes intense seizures. According to the film “Weed”, the young subject used a cannabis strain high in cannabidiol and low in THC. This cut down her seizures from 300 a week to just one every seven days. According to the film Forty other children in the state are using the same marijuana strain to treat their seizures– and it appears to be working.
