1. Beware of producers of D8-THC that do not have the expertise to prepare it from CBD without contamination from D9-THC above the legal limit and synthetic byproducts of unknown effects and toxicities.
  2. Note that D8-THC products that contain substantial amounts of D9-THC may produce effects that are largely due to the effects of the D9-THC.
  3. The presence of D9-THC in D8-THC products can lead to a positive drug test for THC.
