Ĭannabis metabolites can be detected in oral fluid for up to 29 days, in chronic users. Saliva tests are less common than urine tests, but may still be used because they offer a lower ‘adulteration potential, ease of multiple sample collections, lower biohazard risk during collection’ among other advantages. More common use, when the user is smoking cannabis around four times a week, can be detected by a urine test 5 to 7 days after the event.Ĭhronic or daily use can be detected for 10 to 15 days by a urine test. With infrequent use (up to three times a week), a urine test will only detect cannabis for up to 3 days. Urine tests can detect cannabis use for up to 30 days, although this figure corresponds to the heaviest and most frequent use (several times a day). This is a popular form of test because it is relatively easy to carry out, does not need to be done in a laboratory setting, and is still quite accurate. One of the most common forms of drug test is the urine test. It is then metabolised, and the by-products of this reaction can stay in the bloodstream for a while. But this is with a small dose larger, more frequent doses can show up in the blood for as long as 25 days.Ĭannabis enters the bloodstream very quickly, especially when it is smoked (with edible cannabis it may take longer to do so).

These tests measure tetrahydrocannabinol, or THC, as well as other cannabinoids. The main drug tests include saliva tests, urine tests, hair tests, and blood tests. What are the main drug tests, and how good are they at detecting cannabis use? We also discuss different drug tests, how accurate they are, and how likely they are to pick up cannabis use. In this article, we go through some of the factors which determine the length of time cannabis stays in your system. Working out how long cannabis stays in your system, and whether it will be picked up by a drug test, is not an exact science. Drug tests are more likely to pick up on heavy and frequent use. It can stay in your hair for even longer: hair tests can detect cannabis use for up to 90 days.īut whether cannabis use shows up on a test depends on how much cannabis you used, and over what length of time. Cannabis stays in your system for around 30 days and can be detected in your bodily fluids during this period.
