The New Mexico Environment Department (NMED) has enacted an emergency amendment to its hemp manufacturing rules, effective August 1, 2025.
The rule imposes strict new standards on hemp extraction, manufacturing, and warehousing operations statewide, with particular focus on synthetic and semi-synthetic cannabinoids.
The emergency rule applies to any facility operating under the Hemp Manufacturing Act and also covers cannabis manufacturers that use hemp-derived ingredients in their products. It bans the use of synthesized cannabinoids, including intoxicating compounds like delta-8 THC, unless they meet strict purity and sourcing standards.
According to the department’s notice of emergency action, the rule is a direct response to the widespread use of toxic chemicals in the synthesis of cannabinoids like delta-8 THC. The agency cited mounting national reports of serious health issues — including seizures, breathing difficulties, memory loss, and even death — from synthetic cannabinoid consumption, especially among minors.
“Synthetic THC products are being made by exploiting a loophole in federal law and are often marketed in forms like drinks and vapes to children,” states an NMED fact sheet. The rule aims to close this loophole for products made in New Mexico.
The new requirements prohibit hemp facilities from receiving or using semi-synthetic or synthetic cannabinoids unless they fall within a narrow list of approved compounds such as CBD, CBG, CBC, and CBN — and only if the ingredient is demonstrated through third-party lab testing to be at least 98% pure. These provisions officially take effect September 15, 2025.
Additionally, the rule tightens sourcing requirements for all hemp-derived materials. Manufacturers must verify the origin of all hemp products and ensure that THC levels do not exceed 0.3% on a dry-weight basis. Finished products containing hemp must also undergo laboratory testing for THC and CBD levels, contaminants, solvents, and microbial impurities.
To help the industry adapt, the NMED’s Cannabis and Hemp Bureau will host a virtual training session on August 6 from 10:00 a.m. to 11:00 a.m. via Zoom. Public comment on the permanent rule will be solicited in September, with a final rule expected to take effect January 27, 2026.
This emergency rule is currently set to expire in 180 days if a permanent rule is not adopted, although NMED officials say they are on track to finalize regulations before that deadline.
