Cannabis will stay in your body for a varying amount of time depending with how you ingest it and your body’s metabolism. The more you smoke or ingest weed, the more it accumulates in the body and that is why it is easier to detect in heavy smokers. When it comes to the amount of time weed stays in the body, the rate of metabolism plays a huge role. Other factors also include the manner in which you are being tested for weed.
One method of determining the amount of cannabis in the body is to conduct a urine test. This is one of the cheapest methods used to test for this drug. When a urine test is done, you will be testing for THC-COOH, which is a metabolite of THC and not THC itself. When this chemical is present in the body, it is an indication that the body has processed THC. Although urine tests are cheaper, they usually have a long detection period.
The amount of THC present in your system depends with the manner in which you consume cannabis. Since THC is stored in the body fat, it will take some time to accumulate in your system. The more the herb stays in your body, the easier it becomes to detect it through a urine test and this is usually the case with heavy users. A single use of cannabis will cause it to stay in urine up to 8 days, frequent use takes 15 days, regular use will be 30 days, while heavy use takes anything between 45-77 days.
You can also detect THC through a saliva test. However, it stays for a very short time in the saliva. When the police are looking for drugged drivers, they normally do a saliva test at road checks. The THC metabolites normally stay in the saliva for anywhere up to 24 hours after weed consumption for a single use. In heavy users, it can be detected for up to 72 hours.
Conducting a blood test is another way that can be used to determine the amount of THC found in the blood. Since THC is usually stored in the body fat, it won’t be in the blood for long. This test, therefore, can only be effective if it is done within a certain period of taking THC.
Generally, THC is only detectable in blood for about 24, 3 days, and 1 week, for single use, frequent use, and regular use respectively. Given the varying times and different tests, there are methods once can use to pass weed tests. However, that doesn’t mean that it will have been eliminated from your system.
