Cannabis stays in your system for around 30 days and can be detected in your bodily fluids during this period. It can stay in your hair for even longer: hair tests can detect cannabis use for up to 90 days. But whether cannabis use shows up on a test depends on how much cannabis you used, and over what length of time. Drug tests are more likely to pick up on heavy and frequent use.
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. In this article, we go through some of the factors which determine the length of time cannabis stays in your system.
We also discuss different drug tests, how accurate they are, and how likely they are to pick up cannabis use. The main drug tests include saliva tests, urine tests, hair tests, and blood tests. These tests measure tetrahydrocannabinol, or THC, as well as other cannabinoids. According to one papercannabis can be detected in the blood for between 1 and 2 days. Cannabis enters the bloodstream very quickly, especially when it is smoked with edible cannabis it may take longer to do so.
It is then metabolised, and the by-products of this reaction can stay in the bloodstream for a while. One of the most common forms of drug test is the urine test. 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. 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.
With infrequent use up to three times a weeka urine test will only detect cannabis for up to 3 days. 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. Cannabis metabolites can be detected in oral fluid for up to 29 days, in chronic users. For infrequent users, saliva tests can detect cannabis 1 to 3 days after use.
Oral fluid tests work by measuring cannabinoids such as THC tetrahydrocannabinol in the saliva. These cannabinoids enter the saliva after cannabis is smoked, inhaled, or sprayed into the mouth.
Hair tests are by far the most accurate form of drug test and can detect cannabis for up to 90 days after use. Hair tests work because cannabis and other drugs leave trace amounts in the hair follicles after use. Since hair grows at a rate of half an inch per month, scientists can measure what drugs a person has taken by looking at a small segment 1 and a half inches of hair from close to the scalp.
Hair tests do come with some disadvantages, however.
The biggest disadvantage is false positives. False positives in drug tests are when a test shows up as positive, despite the person being tested not having used cannabis. This can happen with hair tests because they measure oil in the hair, and this can be contaminated e.
If you are tested for cannabis at work, you will likely be given an immunoassay test. By having two rounds of testing, the chances of false positives influencing the result are lower. In general, drug testing has got more accurate over time, meaning that false positives are less of a problem than they were in the past.
When you use cannabis, this chemical is absorbed into the blood.

It then passes to the organs and fatty tissues before eventually being metabolised in the liver. THC has over 80 metabolites. Even after the THC has left your bloodstream, these metabolites remain. Drug tests try to pick up these metabolites, either in the hair, blood, urine, or saliva. As well as the extent and frequency of cannabis use, there are several other factors that can affect how long cannabis and THC remain in your body.
A person with more fat relative to their height, age, sex etc.
By contrast, someone who has a lower BMI Body Mass Index and exercises regularly may find that marijuana does not remain in their system for as long. The potency of cannabis can also play a part. Stronger cannabis is likely to remain in your system for a longer period of time since it will contain a greater quantity of THC.
Edible cannabis may also stay in your system for longer than smoked cannabis, since it takes longer to break down than if smoked. If there are other drugs in your system, this can also have an impact on the speed at which THC is metabolised. There are several drugs that increase the amount of THC in your body, among them verapamil, itraconazole, erythromycin, and clarithromycin. Although you can find lots of remedies on the internet for getting cannabis out of your system, none of these are backed up by scientific evidence. Once you have used cannabisyour only real option is to let your body get to work.
