Asthma affects about twenty percent of the population in developed countries, and is a growing problem. In the search for a viable option to combat this increasing health concern, researchers conducted a series of tests involving the use of medical cannabis. Although rats were used as the test subjects, the results were positive. The tests indicate that CBD is an effective means of minimizing the inflammation experienced by asthma sufferers. The rats were divided into three groups; a control group, an asthma group, and an asthma/treatment group. The rats in the treatment group were given a daily injection of CBD, and blood samples were then tested 24 hours later. The blood samples were assessed for levels of cytokines, which affect the interaction and communication between cells. The study showed that the rats treated with CBD experienced a reduction of cytokines, and that CBD also decreased mucus hyper-secretion, which is another symptom of asthma. The encouraging results of this study suggests a need for more rigorous human trials on a larger scale. To truly understand and prove the full benefits of the marijuana plant and its compounds, we need further and more in-depth research. Most people agree and support the use of medical marijuana as a treatment for asthma symptoms, but the specifics of effective treatment are still widely debated. The lack of scientific research is standing in the way of improved quality of life for millions of people. Considering that marijuana is far less expensive than conventional medicines, entirely natural and safe, it should be explored to its fullest potential.
