Often confused for the same thing, hemp and marijuana are two different types of plants from the overall cannabis plant family. The 2018 Farm Bill changed the legal definition of hemp to mean any cannabis strain that contains less than 0.3% THC, so any cannabis strain containing more than that limit is considered marijuana.
While marijuana is still part of the Controlled Substances Act on a federal level, hemp was removed from this list through the Farm Bill, and states were given the right to determine their own industrial hemp plans from there. There are some states that have restricted the sale and use of hemp products, but federally, hemp-derived products are legal for cultivation, use, and sale when following all proper US regulations.
