While it’s legal through hemp, yes, you are still very likely to fail a drug test with Delta-9 THC in your system. However, it may not be for the reason that you think. Likewise, it depends on the type of drug test being used as well as other factors. The frequency of Delta-9 THC use, your metabolism and weight, gender, age, and more also play into it.
It’s important to understand how drug tests work when it comes to THC, though. Most people think the tests look for Delta-9 THC metabolites. Currently, most drug tests aren’t quite that advanced enough yet. Instead, drug tests look for THC metabolites rather than any specific cannabinoid.
Urine tests, for example, work to detect Delta-9 THC's primary inactive metabolite, also known as THC-COOH.
These metabolites can be detected after use, especially in the urine, because they’re stored in our fat cells.
