In order to determine whether plant-derived cannabis medicinal extracts (CME) can alleviate nerve pain symptoms unresponsive to standard treatment, a consecutive series of double-blind, randomized, placebo-controlled single-patient cross-over trials with two-week treatment periods was performed. 18 patients with multiple sclerosis, 4 with spinal cord injury, 1 with brachial plexus damage, and 1 with limb amputation […]
As more states re-allow their inhabitants to use the natural plant marijuana (cannabis), some who grew up with the prohibition mentality are concerned that fatalities from automobile accidents will rise as a result. The authors of this study used the US Fatality Analysis Reporting System to determine the annual numbers of motor vehicle crash fatalities […]
Since cannabinoid (marijuana components) receptors are found in movement related brain regions, some wished to evaluate the effect marijuana may have on human movement. 22 marijuana users average age twenty-four, were matched with 22 non marijuana users average age twenty-five. They completed screening tests, a gait and balance test, and a clinical neurological examination of […]
The healing properties of plants have been used by humans for centuries, and cannabis sativa (marijuana) is one of the oldest ever used for medicinal purposes. In contrast to the whole plant or its extracts, medicinal products which only contain THC have been found to lack effectiveness and lead to unbearable side effects. The authors […]
The hippocampus is a component of the brain associated with long term memory and spatial navigation. There has been ongoing debate regarding the effect of cannabis (marijuana) on hippocampal volume, and whether or not earlier age initiation of use, or higher doses of marijuana have any effect on its size. This study matched 20 heavy […]
Reports of the use of extracts from the cannabis (marijuana) plant being applied topically to open cutaneous wounds, for the purposes of promoting wound healing and relieving wound-related pain, date back to antiquity. Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic skin disease, that classically presents as cutaneous ulcerations which most commonly occur on the […]
It is biologically plausible that marijuana (cannabis) use could affect kidney function, and this cohort study set out to determine any relationships. Data from the Coronary Artery Risk Development in Young Adults (CARDIA) study was used. Past or current marijuana use was reported by 83% (3,131 out of 3,765) of the study participants. The authors […]
Some have questioned the efficacy and safety of “dabbing” in the emerging medical marijuana (cannabis) markets across the United States, and rightly so. The chemistry regarding the creation, combustion and degradation of these products is complex and will not be addressed here specifically. However, this study states that several products of concern to human health […]
In general, the effects of marijuana (cannabis) on nonalcoholic fatty liver disease (NAFLD) are largely unknown. The authors of this study analyzed participant data from the National Health and Nutrition Examination Survey for both suspected and diagnosed NAFLD. Data from 14,080 participants from 2005-2014, and an additional 8,286 from 1988-1994 was evaluated. Prevalence of both […]
For thousands of years mankind has even used the roots of the cannabis (marijuana) plant for medicinal purposes. During the 1st century, Pliny the Elder described in Natural Histories that a decoction of the root in water could be used to relieve stiffness in the joints, gout, and related conditions. By the 17th century, various herbalists […]
