The question of whether HHC (hexahydrocannabinol) will show up on a drug test is a tricky one. While the odds may be lower than with THC, there is still no solid evidence either way. This is because HHC is not specifically THC, and there is no evidence that it breaks down into a metabolite of THC. Therefore, there is no proof that HHC will appear in a standard drug test. So far, there is no evidence to suggest that HHC does not show up on a drug test.
An HHC test can identify these metabolites due to their similar chemical and structural makeup. However, tests may not be able to detect the molecule, meaning that HHC may not cause you to fail a routine drug test. That said, cross-contamination and false positives are still possible due to the similarities in chemical structure. Taking twice as much HHC may increase the time it stays in the body by an hour or two, but it won't make much difference after a day. Before you get tested for drugs, you should understand that it takes longer for your body to get rid of HHC when you use it regularly.
There is also a chance that HHC will not convert to 11-hydroxy-THC when ingested (as Delta 8 and Delta 9 do), which is a common metabolite in drug testing. HHC is believed to contain between 70 and 80% of the concentration of THC, making it more potent than Delta-8 and Delta-10. The speed and efficiency of the functioning of the liver and kidneys determines how quickly the body processes a complex compound such as HHC. It's important to be responsible and make sure the drug test is approved. The cannabis community is divided on this issue: some users claim to have passed the test without any problems; others have failed after using HHC only once or twice. The interesting thing about the 11-hydroxy-HHC metabolite is that it is also a minor active metabolite of THC.
Unfortunately, many dishonest people operating in the HHC industry don't disclose basic data on product testing and contamination. By comparison, it takes about twice as long for the body to process it since it must pass through the digestive system slowly before being absorbed into the blood. HHC, also known as “hexahydrocannabinol”, takes a form similar to THC. Everything looks exactly the same on the drug panel, so there's no way you can prove what type of THC you've consumed. Depending on how much HHC was taken, what type of HHC was taken, and what type of test was used to detect it, you can expect HHC to stay in your body for up to 90 days or six weeks. In the case of THC, the group of metabolites detected by a drug test is known as carboxy-THC or THC-COOH (11-NOR-9-carboxy-THC), which binds to fat cells.
There are no legitimate tests to help us understand if HHC can be detected in a standard drug screening test, so there is no research that can definitively answer this question.
