  1. 1. How Long Does Marijuana Stay In Your System? Posted in March 25, 2010 ¬ 1:42 pmh.admin There are many people who want to know “How long does Marijuana stay in your system.” While the answer to this question is not simple and straightforward, the fact is that if you want to use a drug test effectively, it is a question that requires an answer. So let‟s cut through the misinformation on the Internet and provide one! Before we understand the period of time that marijuana lasts in the system, there are a couple of facts that you need to know. - The presence of marijuana in the system is not dictated by the „high‟ feeling that an individual gets. - The presence of marijuana is detected by the presence of the active chemical THC or Tetrahydrocannabinol. - The time that marijuana stays in the system depends on the amount of marijuana intake and the frequency at which it is consumed. - Marijuana is stored in the body in fat cells. This THC is diffused into the blood stream over a period of time. As THC diffuses, the body becomes clean again. - If you consume marijuana continuously, the rate at which THC can be diffused into the blood is not as fast as the intake. This means that the THC will be present in the system for much longer. - Marijuana drug testing can be conducted using saliva, urine, hair and sometimes blood as the sample. The variation in the amount of time that THC can be detected in these samples is fairly high. - The specific window that you need to check for marijuana consumption depends on whether you are checking this for a teenager you suspect of using for the first time, or a long standing addict. The Saliva Drug Test for Marijuana, or How Long Does Marijuana Stay in Saliva? Marijuana escapes the saliva very soon after consumption. It can be detected by a home saliva drug test about an hour after intake. The accuracy of a saliva drug test (97%-98%) will decrease rapidly about 12 hours after the marijuana was consumed. So while a saliva

The frequency in which someone smokes marijuana (for example, every day for 6 months, or just once) has no bearing on the results of a saliva drug test. The Urine Drug Test for Marijuana The accuracy and time limit in which marijuana stays in the urine depends on the amount and frequency of the drug being consumed. Marijuana can stay in the urine for up to 45 days in cases of very frequent, prolonged use. Basically, the more you use marijuana, the longer it will remain in your urine. If you have just tried marijuana, for example, and that was your only use, it will probably be out of your urine within a week. Those who kick the habit after consuming the drug almost daily can still have THC traces in the urine after a period of 3 weeks and longer. You do need to wait for about 2 to 5 hours after consumption for the marijuana to appear in the urine though. The Hair Follicle Drug Test for Marijuana Just because it has been over 45 days since you consumed marijuana, do not assume that there will be no traces of the drug in your system. The drug that you consume enters the bloodstream and as the blood nourishes the hair, the drug gets into the hair follicles too. As the hair grows, the hair follicles contain traces of THC that can confirm the intake of marijuana. However, this process (of the hair growing out of the scalp enough to be cut) takes about a week and thus it is only a week after intake that the hair follicle home drug test shall give a positive for marijuana use. Drugs take a long time to deteriorate in the hair and therefore testing can be done many days after consumption. A standard laboratory will check up to 90 days but a court or another law enforcing institution can have hair analyzed for more than 3 months as well. While hair drug testing provides a good opportunity to confirm whether someone has been on marijuana, and has the largest detection window, the issue is that this drug is not one of the easiest drugs to hair test. THC does not always incorporate well with the hair. Therefore, it is possible that a frequent user may get a negative reading on a hair follicle drug test while someone who had it just once a couple of weeks back may get a positive

The hair follicle drug test is therefore not considered to be as reliable for marijuana as it is for other drugs like cocaine (and for drugs like cocaine, and all other drugs tested for in a standard consumer hair drug test, hair follicle drug testing is actually found to be better at catching drug use than urine tests). So while the question „How long does marijuana stay in your system‟ is pertinent, there are all of the above factors to consider before an appropriate and correct answer can be given. Even though there is all this discussion about the whole question, if you are concerned, the best thing to do is to just go out there and purchase a home drug test and check out whether you or someone else test clean or not. - Written by Anne Hamilton of Home Health Testing.
