| Dried marijuana flowers contain about 20 percent to 30 percent THC, Hammond said. Vape oils, however, generally run at 70 to 90 percent THC, he said, exposing users to much higher concentrations in each puff. Users can mitigate that by consuming less. | Dried marijuana flowers contain about 20 percent to 30 percent THC, Hammond said.
