CBD Isolate Oils – made with pure CBD Isolate. They don’t contain any other cannabinoids than CBD, which does not support the so-called entourage effect. CBD Isolate is the safest choice for a CBD vaping product, but it’s not the best for CBD Oils.
CBD Full Spectrum Oils – contain CBD extract with many different compounds, mostly other cannabinoids, and terpenes. But they also contain THC in small quantities (usually 0.1% to 0.2% THC). This level of THC is not legal in most parts of the world, and it could be detected by authorities if they chose to inspect it.
CBD Broad Spectrum Oils – probably the best choice for most users of CBD oils. They contain CBD as well as other useful cannabinoids and terpenes, but in contrast to the full-spectrum oil, THC is not detected.
