Side Effects of using CBD

side effects of CBD

CBD is also known as cannabidiol. It is one of the most common ingredients that provides biologically active effects in a body when consumed. CBD is an important ingredient of medical marijuana. It is either extracted directly from hemp, a close relative of marijuana or manufactured in a laboratory. CBD, one of the hundreds of components in marijuana, does not produce the feeling of a “high” on its own. CBD has no psychoactive properties. Because of this, CBD is an appealing option for those seeking relief from discomfort and other symptoms alone without the mind-altering effects of cannabis or the other side effects associated with some pharmaceutical drugs.
