Stability of Nano-Emulsified Cannabidiol in Acidic Foods and Beverages.

Food and beverage products containing cannabidiol (CBD) is a growing industry, but some CBD products contain Δ-tetrahydrocannabinol (Δ-THC), despite being labeled as "THC-free". As CBD can convert to Δ-THC under acidic conditions, a potential cause is the formation of Δ-THC during storage of acidic CBD products. In this study, we investigated if acidic products (pH ≤ 4) fortified with CBD would facilitate conversion to THC over a 2-15-month time period.
