There are restrictions in the USA on registering marks for goods that contain marijuana or hemp. In some cases, hemp-based goods are registerable, but they need to meet certain requirements. An article explaining the hemp issue can be found here: USPTO Examination Guide on Cannabis.
“The 2018 Farm Bill, which was signed into law on December 20, 2018, amends the AMA and changes certain federal authorities relating to the production and marketing of “hemp,” defined as “the plant Cannabis sativa L. and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9 tetrahydrocannabinol [THC] concentration of not more than 0.3 percent on a dry weight basis.” Section 297A. These changes include removing “hemp” from the CSA’s definition of marijuana, which means that cannabis plants and derivatives such as CBD that contain no more than 0.3% THC on a dry-weight basis are no longer controlled substances under the CSA. For applications filed on or after December 20, 2018 that identify goods encompassing cannabis or CBD, the 2018 Farm Bill potentially removes the CSA as a ground for refusal of registration, but only if the goods are derived from “hemp.” Cannabis and CBD derived from 2 marijuana (i.e., Cannabis sativa L. with more than 0.3% THC on a dry-weight basis) still violate federal law, and applications encompassing such goods will be refused registration regardless of the filing date. If an applicant’s goods are derived from “hemp” as defined in the 2018 Farm Bill, the identification of goods must specify that they contain less than 0.3% THC. Thus, the scope of the resulting registration will be limited to goods compliant with federal law.”
