The largest survey on cannabidiol (CBD) to date found nearly half of participants were more likely to stop taking their traditional medications after using CBD.

The survey was conducted by Brightfield Group and HelloMD, which covered a total number of 152,400 members who answered questions about their CBD useage. Cannabidiol is a chemical compound in cannabis that possesses medical qualities but does not get the user “high.”

The most common reasons people claimed they used CBD were to treat depression, anxiety, joint pain, and insomnia. Eighty percent of participants reported CBD products to be effective in treating their symptoms, while 42 percent claimed they stopped using traditional pharmaceuticals after switching to the cannabis derivative.

With 850 brands of CBD products on the market, 8 percent of the consumers surveyed admitted they didn’t know which CBD product they had used. Researchers also noted that patients who used vapes felt the effects of CBD faster than ingesting edibles.

“This landmark survey, in terms of its size and depth, shows the tremendous value that these products have for patients,” Dr. Perry Solomon, the Chief Medical Officer of HelloMD, said. “Hopefully, access for products such as these will help patients all across the country who cannot obtain medication that contains THC.”
