The legality of CBD varies by country and state. In the United States, hemp-derived CBD is legal under the 2018 Farm Bill, which legalized hemp cultivation and the sale of hemp-derived products. However, some states have their own laws regarding CBD, and marijuana-derived CBD is still illegal under federal law.

The legality of CBD in Europe varies by country. In general, CBD derived from hemp is legal in most European countries as long as it contains less than 0.2% THC. This is because hemp is considered to be a legal crop and its products are not considered to be controlled substances. However, some countries may have stricter regulations or different laws regarding CBD, and it is important to check the specific laws of the country in question. In addition, CBD derived from marijuana is still considered to be a controlled substance and is illegal in most European countries.
