The half-life of THC metabolites is seven days. This means that every seven days, the amount of metabolites in your body will decrease by 50%. With this in mind, it can be assumed that your body will be rid of THC metabolites in about 3-4 weeks.

However, it’s super important to note that these numbers can also depend on how much you smoke, how often you smoke, and how much you weigh.

Since THC is fat-soluble, which is why cannabis is great for deliciously fattening edibles, it can easily be stored in your fatty lipid tissue. As a result of this, your fat cells will release the THC metabolites into your bloodstream at a continuous rate, which is certainly not a good thing.

But guess what? You can still pass a drug test without being 100% free of THC metabolites. Since you still need your levels to be below the minimum amount of metabolites for the test, with a typical threshold being 50 mg/mL (whatever that means,) your test results will be negative and you’ll be home free!

Now I’m sure you’re probably thinking, “I don’t care about THC metabolites! I just want to know how to pass a drug test!” Chill out because I’m about lay down the facts.
