Medical marijuana has a long history of being denied coverage by insurance companies. Up to now most insurance companies refuse to cover cannabinoid treatments, typically citing federal regulations as the main reason to decline medical marijuana coverage. This is especially true in the United States where cannabis is a Schedule I controlled substance under the Controlled Substances Act with “no perceived medicinal value”.
In New Mexico, an employee hurt on the job was denied medical marijuana coverage under his worker’s compensation insurance and his suit to force the coverage failed. Beside the ruling in New Mexico, lower courts in Michigan, Maine, Massachusetts, and Connecticut have given similar verdicts to workplace insurers.
