The authors of this study set out to determine the association of cannabis (marijuana) use and tobacco use with bladder cancer. The health records of 84,170 participants from the California Men’s Health Study were evaluated. 41% reported cannabis use, 57% reported tobacco use, 27% reported using both, and 29% used neither. The men were followed […]
Glioma is a brain cancer which is very aggressive and long term survival rates are low because the standard treatments for glioma are largely unsuccessful. It is known that cannabinoids can specifically inhibit glioma growth and neutralize part of the cancer process. This study set out to determine the effect of treating glioma cancer cells […]
The search for effective drugs to treat schizophrenia is complicated by the fact that the disorder is complex and involves multiple neurotransmitters (brain chemicals). The endocannabinoid system is one of the systems which is altered in this disease. In this double-blind study the effects of the cannabis (marijuana) component, cannabidiol, was compared to amisulpride—one of […]
Many automatically associate all types of smoking with similar negative health responses, but surprisingly, cannabis (marijuana) doesn’t usually fit into that negative category. In this study, 10 volunteer stable asthmatic patients participated in a double-blind placebo controlled study in the laboratory of a respiratory unit. They received either placebo, THC, or the synthetic drug salbutamol. […]
Intervertebral disc degeneration is a major contributor to low back pain worldwide. It involves a process of inflammation with alterations to nerve, oxygen, and water levels and increased cell destruction among others. Cannabidiol is a cannabis sativa (marijuana) component with anti-inflammatory and protective benefits. In this study, rats received a disc puncture, followed by an […]
The theory of clinical endocannabinoid deficiency was published in 2001. It was based on the concept that many brain disorders are associated with neurotransmitter deficiencies, and that a similar scenario could be at play in the endocannabinoid system, which would then manifest as certain disorders. The endocannabinoid system was named after the cannabis (marijuana) plant, […]
A central feature of osteoarthritis is the breakdown and loss of cartilage material within the joints of the body. It is known that cannabinoids have an anti-inflammatory effect and reduce joint damage. In this study, the effects of a synthetic cannabinoid was evaluated in vitro (in the laboratory) to determine if it would interrupt the […]
The usage of cannabis (marijuana) to assist in appetite and weight gain in cancer patients is well known, but some may be concerned that the effect will be negative on those who don’t wish to gain weight. This national prospective study over a 3 year period is not only insightful, but should alleviate those concerns. […]
Many individuals, with large numbers from the military veteran population, have significant issues with post traumatic stress disorder (PTSD). The use of cannabis (marijuana) has sometimes been recommended to reduce symptoms. This study was performed to determine the effectiveness of THC, CBD, and of THC plus CBD on the ability to disrupt the re-consolidation of […]
Oral cannabis (marijuana) extracts are commonly used for assistance in controlling epilepsy seizures and symptoms. Some parents report success and much needed relief for their loved ones’ symptoms, but not all types of epilepsy respond the same. In this retrospective chart review, a clearer understanding of which type of epilepsy may respond to marijuana emerged. […]
