It appears that HHC may not break down in the body in the same way as THC. Unlike the delta 8, delta 9, and delta 10 forms of THC, there is some evidence that HHC doesn’t metabolize into 11-hydroxy-THC, which is the breakdown substance many drug panels test for. Basically, HHC can be found only if the test targets HHC. If your test is targeted for THC, the HHC will not be found in your system, since it does not contain THC.
