Lab Mice Agree: Delta-8 Just Like Taking Delta-9
/By Pat Anson, PNN Editor
Laboratory mice at a research facility have figured out something that Congress failed to do when it legalized hemp in 2018: the tetrahydrocannabinol (THC) found in hemp can get you just as high as the THC found in marijuana.
That finding, in a new study led by researchers at the University of Connecticut, undermines one of the tenets of the 2018 Farm Bill, which made it possible for U.S. farmers to grow hemp again as a cash crop. The thinking at the time was that since hemp contained less than 0.3% tetrahydrocannabinol, the main psychoactive ingredient in marijuana, it couldn’t be used to get high.
The mice found otherwise. When given Delta-8 THC derived from hemp twice a day for five days, the mice showed signs of lethargy, dependence and “liking” behavior. Although not as potent as the Delta-9 THC derived from marijuana, researchers reported in the journal Drug and Alcohol Dependence that Delta-8 had similar psychoactive effects on the mice, “including evidence of dependence and abuse potential.”
“So they’re telling us the same thing people buying the stuff in gas stations tell us: (Delta-8) feels like THC,” says Steve Kinsey, PhD, a UConn School of Nursing professor and director of the Center for Advancement in Managing Pain.
Kinsey and his colleagues say Delta-8 and Delta-9 molecules are similar and act in the same way on the body. But while Delta-9 is illegal under federal law, Delta-8 is legally being sold in a wide array of edibles, beverages, tinctures and other products. Because they are made with CBD and THC derived from hemp, they can be purchased without an ID or marijuana prescription – even in states where medical or recreational marijuana is illegal. A recent study found that some hemp-based edibles have 360% more THC than those sold in cannabis dispensaries.
“It’s creating a fight between marijuana and hemp” growers, says John Harloe, an attorney on a Colorado taskforce that is trying to address the different chemical variations of THC and their hazy legal status.
“(Marijuana) must be sold through dispensaries and pay high taxes, while hemp producers can sell essentially the same product but without the same regulations, due to the ambiguity in the Farm Bill,” Harloe said in a statement.
The Food and Drug Administration has been slow to regulate CBD products, but earlier this year the agency sent the first warning letters to companies for selling products containing Delta-8. The letters don’t take issue with Delta-8’s legal status, but focus instead on its unauthorized marketing as a treatment for chronic pain, nausea, anxiety and even cancer.
