Amid the rapidly changing political climate surrounding medical marijuana, researchers at University of South Florida (USF) found that low levels of delta-9-tetrahydrocannabinol (THC), a compound in marijuana, have the potential to slow or halt Alzheimer's disease progression. Extremely low doses of THC were shown to reduce the production of amyloid beta and prevent amyloid aggregates associated with Alzheimer's. "Decreased levels of amyloid beta means less aggregation, which may protect against the progression of Alzheimer's disease," said lead study author Chuanhai Cao, PhD, a neuroscientist at the Byrd Alzheimer's Institute and the USF College of Pharmacy, in a news release from USF. "Since THC is a natural and relatively safe amyloid inhibitor, THC or its analogs may help us develop an effective treatment in the future."
