                                According to the U.S. Drug Enforcement Administration (DEA), hemp seeds are not a controlled substance, regardless of the potential THC yield of the plant they came from, as long as the seed itself contains less than 0.3% THC. This clarification is central to answering the question: can you legally buy hemp seeds? The legality primarily hinges on the seed's tetrahydrocannabinol (THC) content, which must be below the legal threshold, and its intended use.
