29 Feb 2024 --- A “first-ever” randomized trial of commercially available cannabis products indicates that products high in cannabidiol (CBD) can address anxiety better than those containing Δ9-tetrahydrocannabinol (THC), without the potential side effects. CBD products were linked to acute tension reduction, which may translate to longer-term decreases in anxiety symptoms. “We need more data before we can say conclusively that there are long-term, beneficial effects, but the short-term effects were very clear — CBD was associated with tension and anxiety relief with limited harm,” says senior author Cinnamon Bidwell, associate professor in the department of psychology and neuroscience and the Institute of Cognitive Science at the University of Colorado Boulder, US.
