Focusing on the health of our lungs is often a neglected practice, and yet, according to the American Lung Association, approximately 415,000 Americans living today have been diagnosed with lung cancer. Lung cancer is the most common cancer worldwide, accounting for 1.8 million new cases and 1.6 million deaths in 2012 (1). The search for natural remedies to prevent and combat cancer cells in the lungs has led to research on the potential beneficial properties of CBD.
In 2009, the work of researchers studying the effect of cannabinoids against cancer cell invasion was published in the Federation of American Societies for Experimental Biology. Their results showed that cannabidiol upregulated a compound called ICAM-1 in a clinically significant manner, which then led to a subsequent decrease in cancer cell invasiveness.
Given that lung cancer is the most common cancer worldwide and that sufficient oxygen flow is a key factor for producing cellular energy, this study becomes extremely promising and warrants deeper study into how CBD can help stop the spread of cancer cells in the lungs and support lung function in general.
