Cannabinoids are the main active components found in hemp. Cannabidiol (CBD) is one of the most popular cannabinoids in the market today. More importantly, CBD is considered to be a federally legal substance as long as it is extracted from the hemp plant. Its legal label is the reason why you can buy CBD online or find CBD wholesalers like VapeRanger where you can buy bulk CBD. CBD can be used in multiple ways. There are smokable hemp products that have a high content of CBD, but the most popular product categories would include edibles, topicals, and vape products.
