Inhalation exposure to smoke from synthetic "marijuana" produces potent cannabimimetic effects in mice.
Use of synthetic "marijuana" has increased in recent years, produced adverse effects and prompted the temporary DEA ban of five specific cannabinoid analogs, including JWH-018. The objectives of the current study include determining the chemical content of the herbal product, Buzz, assessing its behavioral effects upon inhalation exposure to mice, determining whether CB(1) receptors mediate its pharmacological activity, and ascertaining its biodisposition in blood and various organs. ⋯ Inhalation exposure to a product containing JWH-018 penetrates into the brain and other organs and produces CB(1) receptor-mediated behavioral pharmacological effects in mice. The increased potency of JWH-018 compared to THC, the variable amount of drug added to various herbal products, and unknown toxicity, undoubtedly contribute to public health risks of synthetic cannabinoids.
