Chocolate appears to suppress the signal for THC, and maybe other cannabinoids

Chocolate seems to suppress the signal of the principal psychoactive component of marijuana, tetrahydrocannabinol (THC), and probably other cannabinoids as well, according to new research led by David Dawson, from the cannabis testing lab CW Analytical Laboratories in California. This indicates just how difficult it is to measure the potency of cannabis-infused edibles that are bombarding the marketplace in the US and elsewhere.
