Again, with limited evidence, the safe answer to this question is yes. Till verified data emerges you should play it safe and assume that HHC can be detectable on a standard drug test. There is speculation that HHC will metabolize differently than standard THC, or delta-8, which has also been known to produce a positive result. This difference in metabolic properties is thought to keep HHC from turning into 11-hydroxy-THC, which is the metabolite that drug screens test for. For the time being, it would be best not to risk it if you have a drug test coming up. This is due in part to the unknown nature of how HHC builds up in the body, or how long it takes the body to process.
