Hemp CBD is completely different from cannabis CBD. Hemp also derives from the Cannabis sativa L plant, and while it also contains THC, it contains it in volumes that are less than 0.3% by dry weight. Some governments, including the US, regulate the concentration of THC and permit a specific variety of hemp (called industrial hemp) that is bred with an especially low THC content. This is the reason why, when you type into Google “CBD oil for Sale”, you get hundreds of companies trying to sell you their products – according to most all of them, CBD oil from industrial hemp is 100% legal to sell online and ship to all 50 states.
