Does HHC Show Up on a Drug Test - HHC, or hexa hydrocannabinol, is a synthetic cannabinoid compound. The detection of specific substances in drug tests depends on the testing method and the panel of substances being analysed. While traditional drug tests often target common drugs like marijuana (THC), cocaine, opioids, amphetamines, and benzodiazepines, HHC may not be included in standard drug tests. However, it's important to note that testing protocols and panels can vary. If you have concerns about the detection of HHC in a drug test, it's advisable to consult the organisation or institution conducting the test for specific information.
