text: In Canada, hash oil – defined as a chemically concentrated extract having up to 90% THC potency – was approved for commerce in October 2018.
  In the United States, regulations specifically for hash oil have not been issued as of 2019, but hemp seed oil – along with hulled hemp seeds and hemp seed protein – were approved as generally recognized as safe (GRAS) in December 2018, indicating that "these products can be legally marketed in human foods for these uses without food additive approval, provided they comply with all other requirements and do not make disease treatment claims".
