Health officials in Colorado and Washington state announced Tuesday that they have approved two new marijuana herbal medicines, all of which were found to be safe for use in people with HIV.
The announcement came after the FDA approved one new marijuana medicine and two more herbal medicines in a bid to speed the process of getting approved to market for medical marijuana in those states.
The new medicines, which are currently only approved for patients with HIV, are named Danshen and Danshera.
They contain an active ingredient in the herb known as cannabidiol, or CBD.
CBD has been shown to reduce the side effects of chemotherapy and is used to treat nausea, pain, anxiety and depression.
The new medicines also contain an ingredient known as tetrahydrocannabinol, or THC, a chemical that can make the effects of THC more mild, and the two are currently being tested in trials in people who have severe nausea.
The FDA has not yet announced the approval dates of the other two herbal medicines.
The approvals are the latest steps by the two states in a regulatory push to get approval for marijuana, which is still illegal under federal law.
Marijuana remains illegal under the Controlled Substances Act.
Earlier this month, the FDA granted a final approval to the cannabis herbal products, allowing them to be sold in states where it is legal to do so, such as California, New York and Oregon.
In July, the agency approved a new type of marijuana herb known by its trademark name, Danshan, to treat people with chronic pain and nausea.
The agency said it was a product to be used for chronic pain patients with pain from multiple sclerosis and for patients who have had chronic pain for more than six months.
The approval comes after the Food and Drug Administration, or FDA, announced last year that it was considering expanding its review process for cannabis-based medicines to include cannabis extracts, which could eventually be approved for use as a treatment.
