The amount of time weed stays on your body depends on your rate of metabolism and the frequency of intake. Weed will continue accumulating in your system the more you smoke, meaning that heavy users will have weed in their body longer than one-off smokers. When it comes to the amount of time weed stays in the body, the rate of metabolism plays a huge role. Another crucial factor is the kind of test you take.
One method of determining the amount of cannabis in the body is to conduct a urine test. It is also one of the cheapest methods you can use. When a urine test is done, you will be testing for THC-COOH, which is a metabolite of THC and not THC itself. The presence of this chemical shows that the body has processed THC. Urine tests are cheaper and have long detection periods.
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. In general, a single use will last up to 8 days, frequent use will take up to 15 days, regular use will be up to 30 days, and finally, heavy use will take anywhere 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. Heavy users, on the other hand, can expect THC to be detected for up to 72 hours.
Another method that can be used to determine the level of THC in the body is by doing a blood test. 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. These varying times for different tests mean that there are ways that one can use to pass tests. While at it, it is important to know that passing a test doesn’t mean that you have eliminated weed from your body.
