In the United States, the legal limit of THC in hemp-based products is 0.3% or less on a dry weight basis. This limit is set by the Agricultural Improvement Act of 2018, also known as the Farm Bill, which defines hemp as cannabis sativa L. plants that contain no more than 0.3% THC by dry weight.
Products containing more than 0.3% THC are considered marijuana and are still classified as a Schedule I drug under federal law, meaning they are illegal to produce, distribute, and possess.
It’s important to note that some states have their own laws and regulations regarding hemp and hemp-derived products, and these may vary from the federal regulations. Additionally, the FDA has stated that it is illegal to market CBD as a dietary supplement or add it to food or beverages, although the agency has approved one CBD-based drug for the treatment of seizures associated with two rare forms of epilepsy.
Individuals who use hemp-based products should be aware of their local laws and regulations and should always choose products from reputable sources that have been tested for purity and potency.
