How Long Does Marijuana Stay in Your System?




Determining how long marijuana stays in the system depends on a number of variables, unique to every individual and different drug testing techniques. Are you a regular user or is marijuana use something that you engage with just on special occasions? Are you fit or do you carry extra weight? Is the test performed using your urine, saliva, blood, or hair? Whether you are wondering how long THC will stay in your system because you have a drug test coming up, want to educate your patients or clients, or are just curious, read on to learn more.

THC (Tetrahydrocannabinol), the chemical in marijuana that drug tests measure, will vary in length of detection depending on the amount that is smoked, how often it is smoked, and the genetic makeup of the person. The only way to really know how long THC will be detectable in your body is to set up your own test. Marijuana is fat soluble meaning it is stored in the fat cells of the body. When smoked, THC enters the bloodstream within minutes. When digested, THC enters the bloodstream at a much slower rate, within 20 minutes or up to an hour and a half.

How Long Does Marijuana Stay in Your Blood?

THC is quickly converted into metabolites. Metabolites are molecules that are stored in body fat and are slowly eliminated from the body through urination and defecation. Depending on the blood test’s sensitivity level, results will vary. For occasional users of the drug, THC will usually go undetected in the blood within 12 to 24 hours after use.  For the regular user, THC will generally go undetected in the bloodstream 2 – 7 (or more) days after use. Blood tests are known to be the best option for detecting recent use, but are used less frequently than other techniques due to the nature of the testing procedure. The use of this method is more common in investigations of injuries, cases of driving under the influence, and accidents, where there is suspicion of drug related impairment.

How Long Does Marijuana Stay in Your Urine?

Urine tests for marijuana do not test for real time impairment and can detect THC for weeks after use. These tests tend to be more sensitive than other methods and like the blood test results, depend on the amount of use. Typically, for the occasional user who smokes no more than once a week, they can pass a urine test after 2 days, but THC will occasionally be detected up to two weeks after use. For those who use marijuana regularly, detection of THC will be much longer, extending up to three months in more extreme cases.

How Long Does Marijuana Stay in Your Hair?

Hair tests for marijuana use are more likely to detect regular use of the drug, and less likely to detect occasional use. These tests are known to be one of the most objectionable methods of testing for THC levels because they measure internally absorbed residues that have the ability to remain in the hair for many months after marijuana use.

Regarding the method of use, oral ingestion of marijuana is known to stay in the system much longer than smoking. And like smoking, the amount of time marijuana remains in the system will depend on the length of use, the regularity of use, and the genetic makeup of the individual. The only way to know for sure how fast your body rids itself of THC is to perform your own drug tests at home.

  1. I think... if you're worried about how long it stays in your system, you probably shouldn't be using it. It's great and everything but not worth the risk of losing your job or going to jail.

How Marijuana Affects Brain Function

Marijuana is the most commonly used illicit drug in the United States. It is estimated that 50% of American teenagers have tried marijuana for the first time before they graduate from high school. The main culprit of marijuana’s harmful health effects boils down to THC. THC, which stands for tetrahydrocannabinol, elicits psychological effects when binding with the receptors on nerve cells and fits like a lock. These receptors are commonly found in particular regions of the brain associated with memory, pleasure, and thinking. This article runs down the effects of marijuana on brain performance and how chronic use of the drug affects the individual’s everyday life. Overview on Marijuana Street names: pot, weed, herb. Marijuana is made from Cannabis sativa, a hemp plant. People can take up marijuana through the smoke of the plant’s seeds, flowers, stems, and dried leaves, although marijuana can now be mixed into food.

Does Secondhand Marijuana Smoke Show on a Drug Test?

It’s estimated that nearly 100 million Americans have used marijuana, and 14 million do so on a regular basis. While you may not be one of them, a friend, family member or significant other may be. If this is the case and you are scheduled to take a drug test for a job, you may be worried about whether or not you will pass. People in this scenario often ask, ‘can you test positive for marijuana from second hand smoke?’ Can You Test Positive for Marijuana from Second Hand Smoke? In the U.S. 90% of drug tests are urinalysis tests. This means that a urine sample is tested to detect drug metabolites. In the instance of marijuana the metabolite is tetrahydrocannabinol, more commonly referred to as THC. If a subject has 50 nanograms per milliliter (ng/ml) or more of THC in their sample, then they will be considered positive for use. Tests verified that even after significant, long exposure to second hand marijuana smoke, a person is highly unlikely to reach 50ng/ml, therefore it w

How long cocaine will show in a drug test

Technology plays a great part in helping to detect traces of cocaine through different advanced methods for drug testing, like using urine, blood, saliva and hair. You can detect the existence of cocaine using the following drug tests.  Urine Drug Test To know how long will cocaine show in a drug test, the subject can undergo urine test. It can detect even the slightest trace of cocaine in his urine. However, this will depend on the manner of the cocaine intake. When cocaine is snorted, its detection is possible between 4-10 hours after the intake. When cocaine is injected, its detection is still possible, even after almost a day of the cocaine intake. Cocaine metabolites can still be found even after 2 and ½ days of the intake at a cut off level of 300ng. These metabolites include Benzoylecgonine, ecgonine methyl ester and coca ethylene when cocaine was taken with alcohol. The urine test is done in collecting the urine of the subject and the urine is placed directly into a c
