Asthma negatively impacts approximately twenty percent of the population in developed countries, and is a rising problem. In the hope for a viable option to prevent this increasing health concern, researchers performed a series of tests involving the use of medical cannabis. Although rats were the test subjects, the results were extremely positive. The tests show that CBD is a viable means of minimizing the inflammation suffered by asthma victims. The rats were divided into three categories; a control group, an asthma group, as well as an asthma/treatment group. The rats in the treatment category were injected with CBD. Their blood samples were then assessed 24 hours later. The blood samples were investigated for levels of cytokines, which impair the interaction and communication between cells. The tests indicate that the rats injected with CBD saw a reduction of cytokines, and that CBD also lessened mucus hyper-secretion, which is also a symptom of asthma. The positive results of this study should lead to more rigorous human trials on an expanded scale. To totally understand and confirm the benefits of the marijuana plant and its compounds, we need to conduct further, in-depth research. Most people are aware of and support the use of medical marijuana as a helpful treatment for asthma symptoms, but the exact method of effective treatment are still continually debated. The absence of scientific research is a barrier, preventing an improved quality of life for millions of people. Considering that marijuana is so much less costly than other more accepted medicines, absolutely natural and safe, it should be pursued to its greatest potential.
