CBD or cannabidiol is extracted from the cannabis plant and typically diluted with coconut or hemp seed oil. There are no side effects from long-term consumption. It is usually marketed and sold as a supplement rather than a medication. At the present time, the FDA doesn’t regulate the purity of dietary supplements. It is a good idea to validate the quality of the CBD before consumption. If the hemp plants were treated with toxic pesticides or raised in soil contaminated with heavy metals, the CBD extract is not no longer pure and not necessarily safe. CBD can also interact with specific medications, increasing the level of blood thinners. Reactions to CBD are not common or severe. Some people report a calming effect, which at high doses, results in fatigue. Because CBD interacts with cannabinoid receptors in the salivary glands and suppresses the secretion of saliva, some people complain of dry mouth. There have also been reports of lightheadedness. Very high doses of CBD may cause a slight drop in blood pressure. However, there has never been a case of fatal CBD overdose. CBD is a non-psychoactive cannabinoid, which means that it doesn’t provide a “high” sensation. THC (tetrahydrocannabinol), another compound of the cannabis plant, is psychoactive. CBD products that do not contain THC are outside the regulations of the U.S. DEA Controlled Substances Act. These products are legal to sell and consume in all fifty states. There are different degrees of restriction in various states, but people are able to order CBD online without a medical cannabis license.
