[3] [4] Cannabidiol (CBD) is another major constituent of some cannabis plants. [5] Conversion of CBD to THC can occur when CBD is heated to temperatures between 250–300 °C (480 to 570°F), potentially leading to its partial transformation into THC. [6] At least 113 distinct cannabinoids have been isolated from cannabis. [7]
In the typical operating temperature range of e-cigarettes (250–400 °C (482–752 °F)), 25–52% of CBD is transformed into other chemical substances: Δ9-THC, Δ8-THC, cannabinol and cannabichromene as predominant pyrolysates. From a chemical point of view, CBD in e-cigarettes can be considered a precursor of THC. [28]
36. Flame filter prevents flame from igniting herb which instead is heated to vaporization temperature. A vaporizer heats herbal cannabis to 157–210 °C (315–410 °F), which causes the active ingredients to evaporate into a gas without burning any plant material (the boiling point of THC is 157 °C (315 °F)).

It’s hard to get a clear answer on whether people who regularly use cannabidiol (CBD) run the risk of a positive drug test for marijuana. Urine and hair screening tests look for delta-9 ...
CBD is common in vape products. Conversion of CBD to THC can occur when CBD is heated to temperatures between 250–300 °C, potentially leading to its partial transformation into THC. [89] CBD is one among the most suspected ingredients involved in VAPI. [90] Synthetic cannabinoids are increasingly offered in e-cigarette form as "c-liquid". [91]
