It’s been hailed as a wonder drug and it’s certainly creating wonder profits. By some estimates, the Cannabidiol (or CBD) market could be worth $20 billion dollars by 2024.
While users tout its effectiveness in pain relief, up until now there’s been limited experimental human research on the actual effectiveness of the drug. However, a new study led by University researchers sheds light on the ability of CBD to reduce pain along with the impact that the so-called placebo effect may have on pain outcomes.
“For science and the public at large the question remained, is the pain relief that CBD users claim to experience due to pharmacological effects or placebo effects,” says Martin De Vita, a researcher in the psychology department in the College of Arts and Sciences. “That’s a fair question because we know that simply telling someone that a substance has the ability to relieve their pain can actually cause robust changes in their pain sensitivity. These are called expectancy effects.”
