Safety of cannabis
According to an approved statement from the US Department of Justice in 1988, "Nearly all medicines have toxic, potentially lethal effects. But cannabis is not such a substance. There is no record in the extensive medical literature describing a proven, documented cannabis-induced fatality. In practical terms, cannabis cannot induce a lethal response as a result of drug-related toxicity."
From January 1997 to June 2005, the U.S. Food and Drug Administration (FDA) reported zero deaths caused by the primary use of cannabis. In contrast, common FDA-approved drugs which are often prescribed in lieu of cannabis (such as anti-emetics and anti-psychotics), were the primary cause of 10,008 deaths. The cannabinoid THC has an extremely low toxicity and the amount that can enter the body through the consumption of cannabis plants poses no threat of death.
Glaucoma
In glaucoma, cannabis and THC have been shown to reduce intra-ocular pressure (IOP) by an average of 24% in people with normal IOP who have visual-field changes. In studies of healthy adults and glaucoma patients, IOP was reduced by an average of 25% after smoking a cannabis "cigarette" that contained approximately 2% THC—a reduction as good as that observed with most other medications available today, according to a review by the Institute of Medicine.
Spasticity in multiple sclerosis
A review of six randomized controlled trials of a combination of THC and CBD extracts for the treatment of multiple sclerosis (MS) related muscle spasticity reported, "Although there was variation in the outcome measures reported in these studies, a trend of reduced spasticity in treated patients was noted." The authors postulated that "cannabinoids may provide neuroprotective and anti-inflammatory benefits in MS."[58] A small study done on whether or not cannabis could be used to control tremors of MS patients was conducted. The study found that there was no noticeable difference of the
