Like vape cartridges that contain CBD, THC, or another cannabinoid, these cartridges contain distillate oil consisting of delta-8-THC suspended in natural Cannabis sativa flower oils. Since no Cannabis sativa strains yet exist that contain large quantities of delta-8-THC, most D-8 consist of isolated D-8 THC that has been combined with cannabis terpenes, flavonoids, and other natural constituents of the hemp plant. High-quality D-8 cartridges only consist of substances that are naturally present in Cannabis sativa flowers, and cartridges that contain additional substances such as flavorings or fillers are low-quality and could be dangerous.
