How Long Does Marijuana Stay in Your Urine?

Even though the ‘high’ from smoking marijuana does not last long, it is possible to detect the drug in your body weeks after consumption. The probability of marijuana being detected in your system varies depending on the amount you consume and how often you have been smoking or ingesting it. The active ingredient in marijuana, THC, gets into the bloodstream rapidly but it is not absorbed immediately. The amount of time it takes for it to be absorbed varies from 20 minutes to an hour and a half. Marijuana in your urine can be detected using a simple test. 

How Does Your Body Process Marijuana?

The body depends on the metabolism to get rid of marijuana. The fact that people have different metabolic rates means that their bodies will dispose of marijuana at different rates. People process cannabis differently even though they may have similar age and lifestyles. Those who have higher fat levels may not get rid of cannabis easily. This is because cannabis traces are held in fat cells.

So, How Long Does it Really Stay in Your Urine?

Urine testing is a reliable way for marijuana testing. Even though there is no specific formula for measuring the amount of time that marijuana stays in your urine, it is possible to estimate. The duration may vary from less than 30 to 120 days depending on your consumption.

Marijuana can stay in your system for a long time because THC attaches to fat cells after passing from the bloodstream. For those who use weed occasionally, (about three times a week), it may stay in your urine for three days. For those who use it more than four days a week, marijuana may stay in your urine for up to seven days. For chronic users (those who use it daily), it may even remain for up to 15 days after the last consumption. For those who use it multiple times a day, marijuana may be detected in the urine even after 30 days.

How Accurate are Urine Tests?

Even though urine tests may give false positives when testing for other drugs, marijuana tests are rarely wrong because they are a lot more sophisticated. The first step is for the lab to use an immunoassay test for screening. If the results are positive, the sample is screened again using GCMS. Nothing can cause a marijuana urine test to show a false positive. In the past, some drugs were known to cause false positives. However, the tests have been modified to solve that problem.

Even though there are plenty of methods that are alleged to help fool the test, most of them do not work. The following are some of those techniques: 

Washing it Out

This technique involves drinking lots of water and fluids which will cause frequent urination. This is thought to help the body get rid of marijuana from your system. You can then take vitamin B12 to give your urine some colour before the test. This reduces the concentration of THC in your system, but it does not eliminate it. 

Drug Screening Agents

Drug screening agents include herbal teas and other substances that are believed to help you get rid of marijuana traces from the body. Even though some of them may be effective, you need to use them for long periods. The period is usually long enough for the body to have eliminated marijuana naturally. 

If you have to take a marijuana test on short notice, you are likely to fail it if you have been smoking or ingesting it. This is because there is no fast and simple way to get rid of marijuana from your system. If you are caught driving while intoxicated with marijuana, you may be charged.

What Can You Do to Help Marijuana Metabolise Faster?

Even though there is not much you can do to help marijuana leave your system faster; there are a few things you can do to help it break down. Some of them include; following a healthy diet and exercising.

Factors that Affect the Period When Marijuana Can Be Detected in Your Urine

Frequency of Use

If you take marijuana frequently for a prolonged period, THC is likely to build up in your system. This means that it may be difficult to get rid of it. People that consume marijuana a few times a month can get rid of it in a few days. 

Method of Consumption

The way that you consume marijuana has a significant impact on the amount of time that it can be detected in your urine. If you smoke, your body can get rid of it after a few days. If, however, you ingest it, it metabolises slowly, and it can be detected in your urine for longer. 

Use of Other Drugs

Some drugs may increase or reduce your metabolic rate. If your metabolic rate is low, your body may not be able to get rid of marijuana fast. Marijuana in your urine may remain detectable for a long time. Your rate of metabolism can have a dramatic effect on the time that marijuana can be detected in your urine.

The bottom line is that marijuana can stay in your system for a few days or months depending on several factors. Presence of marijuana in urine greatly depends on how often you use it and whether it was smoked or ingested.
