State Governments Are Starting To Ban Delta-8 THC State Governments Are Starting To Ban Delta-8 THC Last month, a warning was raised by a chemist on the constituents of delta-8 THC, its production techniques, and other unknowns. Delta-8 THC is fast becoming an ever-present compound. While this may seem like good news, it is a thing of concern. There seems to be a lot of misinformation about this compound, with a lot of concerns about the production, labeling, and marketing strategy. Colorado has recently banned sales of delta-8 THC products, and other states like Vermont have already removed it from the shelves.
