Cannabidiol (CBD) is found in both hemp & marijuana. CBD is non-psychoactive & has anti-inflammatory, analgesic, anticancer, antiviral, antifungal, & anti-seizure activity. It is legal to purchase in the United States & has become an extremely popular supplement.
Hemp is distinguished from cannabis by the level of THC. If the plant has less than 0.3% THC, then it is classified as hemp & is legal to grow in the United States. Any amount of THC greater than 0.3% classifies the plant as cannabis & is highly restricted.
Hemp is becoming more popular, not only for the CBD content, but for the production of cloth fabric, paper, and may one day threaten other industries. CBD oil is primarily obtained through extraction from hemp plants.
CBD can be useful to patents new to Medical Cannabis, as its anti-anxiety effects may offset the psychoactivity that accompanies other cannabis compounds, like THC.
