CBD has also been demonstrated to exert a chemopreventive effect in a mouse model of colon cancer. In this experimental system, azoxymethane increased premalignant and malignant lesions in the mouse colon. Animals treated with azoxymethane and CBD concurrently were protected from developing premalignant and malignant lesions. In in vitro experiments involving colorectal cancer cell lines, the investigators found that CBD protected DNA from oxidative damage, increased endocannabinoid levels, and reduced cell proliferation. In a subsequent study, the investigators found that the antiproliferative effect of CBD was counteracted by selective CB1 but not CB2 receptor antagonists, suggesting an involvement of CB1 receptors.
In the United States, the CBD drug Epidiolex has been approved by the Food and Drug Administration for treatment of two epilepsy disorders. The U.S. Drug Enforcement Administration has assigned Epidiolex a Schedule V classification while non-Epidiolex CBD remains a Schedule I drug prohibited for any use. CBD is not scheduled under any United Nations drug control treaties, and in 2018 the World Health Organization recommended that it remain unscheduled.
As provided in Sec. 7606 of the 2014 Farm Bill industrial hemp may only be grown as part of a research or pilot project. The 108th General Assembly enacted Public Chapter 916 regarding the growing of industrial hemp in Tennessee. The Act removes industrial hemp from the definition of marijuana in the criminal code. The cultivation of industrial hemp is now available as an option for Tennessee farmers on a limited basis. The Commissioner of the Tennessee Department of Agriculture has promulgated regulations establishing a program of licensing authorized hemp producers.
The challenge to find lighter and longer-lasting energy storage devices (e.g., batteries) can be found in almost every sector. Hemp could prove to revolutionize battery life by aiding in the development of faster, smaller and cheaper supercapacitors. A supercapacitor is an energy storage device that can discharge powerful infusions of energy, needed only in small bursts. Such powerful discharges are used in braking systems of electric vehicles, the powering on of computers and new technologies such as rapid phone charging or cordless tools.
