If you're going to take a drug test for a new job or some other reason, the test will generally be designed to look for one specific cannabinoid: tetrahydrocannabinol, or THC. THC is a psychoactive cannabinoid that makes people feel high when smoking weed or consuming other cannabis products. Tests will mainly try to focus on detecting THC or THC metabolites, like THC-COOH, which can be stored in your fat cells. This is because the presence of THC is the clearest indicator that a person has been using recreational or medical marijuana, and it’s quite easy to spot in a typical urine test. For this reason, when people talk about doing a detox from weed before a drug test, their main focus is on THC detoxification. A THC detox kit can help you eliminate THC from your body so that it won’t show up on the tests, but results and marijuana detox timeframe models can vary from one method to the next.
