How long does THC stay in my urine?

Asked 3 years ago

I’ve been taking CBD for several years, which has a tiny amount of THC in it. I’ve had to stop taking it as I’m starting a job soon that has zero-tolerance. So I’ve bought some test strips, and it’s showing in my urine. Can anyone give me any indication of how long this might be detected, please?

There are many different methods of testing for THC in a person's body, and each has a different window of opportunity, though they vary depending on a number of factors, such as concentration of doses or frequency of use. Thus, it's difficult to determine exactly how long it might be detected.

The shortest detection methods are blood and saliva, which should be impossible after a few days.

Next is urine the most popular testing method. Although it can be difficult to detect in only a few days, regular users can still have detectable THC in their urine after a few months. Though you probably don't have to worry about it being that long. Although the rate of your metabolism plays a part (THC is metabolised through your fat cells), in order for it to be detected longer than 30 days after last use you need to be a chronic heavy user (meaning consumption of high-THC compounds multiple times a day).

Given that you take CBD and not specifically THC, you would probably be classified as no more than a moderate THC user (chronic, at best). This means that it could take anywhere from 5 to 15 days to be undetectable in your urine, though due to the fact that you've been taking CBD for several years and aren't sure of the exact THC dosage, it could take up to 30 days as a worst-case scenario.

Hair, on the other hand, can hold traces of THC up to 90 days, but it's an incredibly unpopular method of testing.

Another factor to consider is your own body. If you're young, of healthy weight, and live an active lifestyle, it will take less time for your body to metabolise it out of your system. If you're old and unhealthy, it'll take longer.
