How Long Does Marijuana Stay in Your System?
Weed also known as cannabis or marijuana is the most used recreational drug by Americans-a poll says that half of the US adults have tried marijuana. The major component of marijuana is THC-tetrahydrocannabinol, which is basically detected by the drug tests. The hair, urine, and blood tests can detect the THC for many days while the saliva test can detect the THC for a few hours from the last dose.
Factors Influencing the THC Detection Time?
A number of factors govern the time for which the THC stays in your system, including:
- The frequency of use
- The amount of use
- Body Mass Index
- Body’s metabolism
- Gender
- Hydration
- Age
THC Detection Time Varies with Dose
Marijuana drug tests detect the concentration of THC in the tests. So, a person who is a chronic smoker and smokes several times a week has a high concentration of THC in the blood than those who smoke occasionally. Therefore, it is recommended that chronic smokers use Toxin Rid to cleanse their system and lower the concentration of THC in their body before taking the drug test.
Immunoassay or home-based testing devices are used for the qualitative measurement of THC in the blood in the form of a positive or negative test. In the case of a positive test, a lab-based confirmation test is conducted for more detailed results.
A 2017 study reports the test results in the heavy, light, and non-smokers. The study was based on 136 marijuana users who were tested for hair follicle drug tests. The hairs were cut to 1 centimeter and tested. 77% of the heavy users and 39% of the light users produce positive results, while no non-smokers were not tested positive. Marijuana detection time chart in different drug tests can help you to better understand the effect of dosage and frequency on detection.
Another study on cannabis users was reported in 2012. The persons were smoking a single cigarette with 6.8% THC with 14 frequent and 10 occasional smokers. THC was detected in 100% of the frequent users and 60-100% of the occasional users with THC concentration high in the urine in 0.6 to 7.4 hours after smoking. The study concluded that Toxin Rid was effective in reducing THC concentrations in the urine of the participants.

Body Fat
Body fat also contributes significantly in determining the fact that how long will marijuana stay in your system. The THC is stored in the fat, so for a person with high fat, it is difficult to remove THC.
Exercise
Exercise doesn’t affect the rate at which the THC is excreted from the body. The surprising fact is there is a great likelihood of positive tests if you exercise right before the test.
A study was conducted to evaluate the effect of exercise on cannabis users. 14 regular marijuana users were tested after 35 minutes of exercise on the stationary bike. The results show that there is an increased concentration of THC suggesting that the exercise causes the body to release the THC at a faster rate. The THC is stored in the fat cells, so the users with high BMI had more THC levels.
Apart from the above factors, the form of marijuana being used is also considerable. As Healthwatch Leicestershire specifies, weed that is ingested stays longer in the blood than the weed that is smoked. As THC is stored in the body fat, the faster the metabolism of your body easily the weed gets out of your pee. For the high dosage, it becomes difficult to eliminate the THC from the body.
How Long is Marijuana Detected by Various Drug Tests?
The drug test detects marijuana and its metabolites in the body. The metabolites of the weed stay in your blood system for a long time after the use even its effect has worn off. Here, is the summary of the detection time of the weed by various drug tests.
Urine Drug Testing
How long does it take the pot to leave the system for a urine drug test depends upon the frequency of use. For our convenience, cannabis users can be divided into the following categories.
| Cannabis User | THC stay in the urine |
| Infrequent User (less than two times a week) | 1 to 3 days |
| Moderate User (four to five times a weak) | Up to 7 days |
| Heavy User (daily use) | 10 to 21 days |
| Chronic User (multiple times a day) | Up to 30 days |
Urine drug testing is the most commonly employed test to detect the THC in the system as it is easy and produces instant and accurate results. Relying on detox drinks may be not enough to beat a urine drug test – you may need a solution like Testclear Powdered Urine kit. Quitting the marijuana intake, proper hydration, and some exercise can help you to excrete the THC from the urine and pass a drug test.
The best way to clean your system for a urine drug test is to drink enough water and pee out to let the body clean the metabolites because the cannabis is long detectable in urine.
The basic test used for urine testing is immunoassay because it is quick and effective. While if confirmation is required for the preliminary results, the GC-MS is employed in the laboratory.
Blood Drug Testing
The metabolites of marijuana stay in the bloodstream for a significant time depending on the usage. After inhalation, the weed is distributed in the blood and tissues and can be reabsorbed. Weed stays in your blood system for many days after use.
| Frequent Use | Up to 36 hours |
| Chronic Use | Up to 7 days |
| Heavy Chronic use | Can be detected up to 21 days |
Blood tests are considered more effective than other tests because it provides detail about various kinds of drugs. From alcohol to opiates, and barbiturates, several drugs are tested by a blood test.
Saliva Drug Testing
Saliva drug test detection time is small as compared to other drug tests. Weed enters the saliva after the ingestion or exposure to secondhand smoke. Saliva can be detected for the following time after the use:
| Infrequent User | Up to 24 hours |
| Frequent User | Up to 2 days |
| Chronic User | Up to 29 days |
Oral fluid strips are used for roadside testing to detect the drugs in the system. Various detox mouthwash has been advertised and employed by the users to beat the saliva drug test.
A saliva drug test is one of the easiest tests that provide immediate results. Just a collection stick with cotton or absorbent is used to collect the saliva from the cheeks and then the sample is analyzed. Saliva is a fluid that is collected from specific saliva glands for the purpose of drug detection.
Hair Drug Testing
Hair follicle drug test is one of the most authentic drug tests to detect the metabolites of the drug in the body. The marijuana and its metabolites are detectable in your hair follicles drug test for about 90 days. The drugs reach the hair follicles via the blood vessels and can be detected for a long time.
The study present that the hair follicle drug test is best suited for heavy or daily users.
A hair follicle drug test is performed on the hairs ranging from 0.5 to 1.5 inches in length. If a person is bald, then the hairs can be taken from the face or hands. As with other methods, first, the Immunoassay test is performed and then confirmation is done by the GC-MS in the lab. Weed is easily detectable in hair follicle drug tests and the result can be received with a few days.
Various detox methods from the Jerry G to Macujo, including the use of Aloe Toxin Rid Shampoo, are used to pass the hair drug test. But the weed will show up in the hair follicle drug test again after you perspire or oil returns to the hairs. So, a careful method is necessary to remove the toxins from the hair follicles.
Summary Marijuana Detection Time Chart
| Marijuana User | Urine Drug Test | Blood Test | Saliva Test | Hair Follicle Test |
| Infrequent | 1 to 3 days | Up to 24 hours | Up to 24 hours | For 90 days |
| Moderate | Up to 7 days | Up to 36 hours | Up to 2 days | For 90 days |
| Heavy | 10 to 21 days | Up to 7 days | Up to 29 days | For 90 days |
| Chronic | Up to 30 days | Up to 21 days | Up to 29 days | For 90 days |
How is THC Metabolized?
As soon as you ingest cannabis, it is rapidly broken down into metabolites and modified to other forms. The THC makes its way to the liver via the bloodstream where it is metabolized. Generally, the THC metabolism produces up to 80 metabolites in the body that are detected by drug tests.
The major psychoactive component of the THC is delta9 THC which further metabolizes to Glucuronide. After one week, the THC and its metabolites still remain in the body and need three weeks for its removal from the body, if you don’t intake more drugs.
According to HealthwatchLeicestershire, more than 55% of the THC is excreted by the feces from the system and about 20% is excreted by the urine.
Could You Accelerate the THC Metabolism Process?
There is not a single tip to drastically get the THC out of your body because it is a natural process. Once the THC enters the body, it takes time to completely flush the toxins from the body. But following some measures can fasten the process: like hydration, exercise, and prohibition from intake of drugs.
If you are an occasional user and at the border of the positive or negative test, then drinking water and some exercise can easily excrete the THC out of your body.
As these natural processes are slow and require time, so most drug users opt for detox products and kits to pass the drug test. The success rate of these detox products is significant if we count for the online reviews. You can pass the drug test with these urine kits and detox drinks, if you choose the best ones like Toxin Rid. But in some cases, using detox pills or drinks may be harmful to the body. Be consistent while the detoxification process to naturally get the weed out of your pee.
Could Secondhand Marijuana Cause Positive Drug Test Results?
It is not common that a person can get a positive result from secondhand marijuana but it can be possible in some cases. In research, both the smokers and nonsmokers were seated together in two rooms, ventilated and non-ventilated. In the ventilated room, the THC concentration in the non-smokers was not enough to meet the cutoff level. While in the non-ventilated room, the THC was detected in only one non-smoker urine after four to six hours of exposure.
In one study, the participants were seated for one hour with a high level of THC (11.3%). THC was detected in the one non-smoker urine but it was rare and in the immediate hours of exposure.
Conclusion
Marijuana is one of the most widely used recreational drugs by adults and teens. Either for employment or custody cases, the drug test is necessary and THC is the major concern for the user. How long does it take for the weed to get out of your system for the drug test depends on various factors from your metabolism to age and frequency of use.
Among the drug tests, the weed will show up in the hair follicle drug test for 90 days. THC is stored in the fat tissues, the more frequently and heavily you use the marijuana, the longer it will take to get THC out of your system. A urine test can detect various compounds for a wide range of times up to thirty days. For the infrequent user, THC is less likely to test positive.
