Hemp-derived products cleared for U.S. air travel in another sign of federal acceptance

U.S. aviation authorities have changed course on cannabidiol and now allow it on airplanes, as long as it comes from hemp.

The U.S. Transport Security Administration recently updated its guidance on medical marijuana to clarify that CBD products are allowed as long as they were produced legally.

That means CBD products must be derived from legally grown hemp, though there’s no way to tell whether a CBD product came from a plant that was grown in accordance with U.S. law.

The TSA guidance could have significant implications for businesses selling hemp-derived CBD.

Those products have been subject to sporadic seizures, even after Congress changed the law last year to legalize hemp and hemp products.

The agency says in its updated marijuana guidance that its efforts are “designed to detect potential threats to aviation and passengers,” not enforce federal drug law.
