I am wondering how long weed will show in my system?\"**\n\nMarcus L.\n\n-------------------------\n![Hello5-min.png](https://hellomd-cms.s3.us-west-2.amazonaws.com/Hello5_min_be7664c2cf.png)\n\nMany factors influence how long a chemical lingers in the body or how long it shows up in a drug test. These are some of them:\n\n- the amount of body fat you have\n- how frequently do you ingest marijuana\n- the sensitivity of a drug test depends on how much you may smoke/ingest\n\nAlcohol and other drugs can vanish from the body in as little as a few hours. Weed, on the other hand, lasts far longer.\n\nTetrahydrocannabinol, or [THC](https://www.hellomd.com/tag/thc), can be detected in **urine**, **blood**, and **hair** for several days after usage, although saliva tests can only identify THC for a few hours. This is due to the way THC is metabolized in the body.\n\nThe short answer - in a standard blood test marijuana may show for 1 to 2 days on average. If you are a heavy consumer it may be detectable for as long as 25 days. It is highly variable.\n\nTHC is a lipid-soluble molecule that has been verified in your system. This implies it binds to fat in the body, increasing lean mass. Check out this [HelloMD article](https://hellomd.com/articles/how-long-does-cannabis-stay-in-your-system) on the topic.\n\nPatty J.\n_____________________\n\n![Hello2-min (1).png](https://hellomd-cms.s3.us-west-2.amazonaws.com/Hello2_min_1_2f3b250795.png)\n\nI can't answer from a doctor's perspective, but I have been to the phlebotomist quite a few times and have had my blood work done. No one ever mentioned THC or cannabis and I am quite certain that there was a good amount of THC in my blood during the blood draw. I would imagine, that if they are not looking for it, they will not pull it up in a standard test. If however, someone is doing a test specifically for that, to be on the safe side, I would not consume for a month before the test. Hope this helps!\n\nRyan M.\n_____________________\n\nNo, the only way THC will show up in a blood test is if the doctor is testing for it specifically. Since a standard blood test is not looking for the presence of any THC, none will be detected. Hope this helps!\n\nAlex M.\n_____________________\n\n![Hello3-min.png](https://hellomd-cms.s3.us-west-2.amazonaws.com/Hello3_min_5e77197f9f.png)\n\nYou may be required to take a THC blood test in certain circumstances - particularly if you are in a rehabilitation program or have an employer with strict anti-cannabis rules. However, please keep in mind your \"standard blood test\" will often not test for THC. It is usually a Complete Blood Count (CBC) panel that will provide diagnostic information on your liver, kidney, and blood cell status. The primary function of this test is to detect diseases. \n\nTypically, cannabis will stay in your system for about 1-2 days after consumption. However, if you are a heavier user, it can stay for up to 7 days or even longer. With that said, variables that can affect how long THC is present in the blood include metabolism, body mass index, and frequency and amount of cannabis consumed. If you are going to have a THC blood test soon, I suggest abstaining from cannabis consumption for three weeks to be safe! \n\nVeronica B.\n_____________________\n\n![Hello1-min (1).png](https://hellomd-cms.s3.us-west-2.amazonaws.com/Hello1_min_1_242fa4bae4.png)\n\nLike others have mentioned here, THC from cannabis won’t show up in a “standard” blood test, so your employer, doctor, or whoever is requesting the THC blood test would have to be looking for it specifically. Unlike urine tests, blood tests detect the active presence of THC in the bloodstream.\n\nIn the case of smoked marijuana, THC peaks rapidly in the first few minutes after inhaling, often to levels above 100 ng/ml in blood plasma. It then declines quickly to single-digit levels within an hour. \n\nHigh THC levels are therefore a good indication that the subject has smoked marijuana recently. THC can remain at low but detectable levels of 1-2 ng/ml for 8 hours or more without any measurable signs of impairment in one-time users. In chronic users, detectable amounts of blood THC can persist for days.\n\nCheck out this article for more information re: [THC blood tests](http://www.canorml.org/healthfacts/drugtestguide/drugtestdetection.html#blood).\n\nMelissa P.","image":{"childImageSharp":{"fluid":{"base64":"data:image/png;base64,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","aspectRatio":1,"src":"/static/313fd9d2441b41b5f6a47f1aec93c721/97f33/551ad7cc624387db30808d61a806fac5.png","srcSet":"/static/313fd9d2441b41b5f6a47f1aec93c721/69585/551ad7cc624387db30808d61a806fac5.png 200w,\n/static/313fd9d2441b41b5f6a47f1aec93c721/497c6/551ad7cc624387db30808d61a806fac5.png 400w,\n/static/313fd9d2441b41b5f6a47f1aec93c721/97f33/551ad7cc624387db30808d61a806fac5.png 483w","srcWebp":"/static/313fd9d2441b41b5f6a47f1aec93c721/e4e06/551ad7cc624387db30808d61a806fac5.webp","srcSetWebp":"/static/313fd9d2441b41b5f6a47f1aec93c721/61e93/551ad7cc624387db30808d61a806fac5.webp 200w,\n/static/313fd9d2441b41b5f6a47f1aec93c721/1f5c5/551ad7cc624387db30808d61a806fac5.webp 400w,\n/static/313fd9d2441b41b5f6a47f1aec93c721/e4e06/551ad7cc624387db30808d61a806fac5.webp 483w","sizes":"(max-width: 483px) 100vw, 483px"}}}}},{"node":{"id":"Question_12375-markdown","title":"Genetic Testing ","slug":"genetic-testing","content":"\"Is there a preferred lab to do the genetic testing?\"\n_____________________\nSpeaking to the HelloMD staff, there doesn't sound like there is a preferred lab to do genetic testing for flowers, etc.   However, there is a fair amount of \"cheating\" going on.

Thoughts? and reccomendation if there is a type of CBD ratio that would be ok\"\n_____________________\nHello, \n\nThe simplest course of action would likely be switching to edibles, sprays, tinctures or oils for at least two weeks prior to surgery. Otherwise, the medical reason for using CBD would factor into the decision. Smoking nicotine only damages health and has also been shown to dramatically increase respiratory complications during and after surgery. Nicotine would also impede post-surgery wound healing. CBD, on the other hand, may be vital to the patient’s short term health, e.g. as an anticonvulsant. So a physician would weigh risks vs benefits in order to make an informed recommendation. \n\nThe amount of CBD used could also factor into the decision, as very high amounts may alter how your body metabolizes many agents used during general anesthesia, and can also reduce your body's ability to form blood clots.  For these reasons, and many more, you should always be forthright with your surgeon, and especially with your anesthesiologist. However, unless a very high amount of CBD is used, as previously mentioned, the main consideration would likely be the prevention of respiratory complications, both during and after surgery.\n\nIn order to evaluate your specific case properly, I advise that you consult with a physician. This information should not be taken as medical advice.\n\ndrkim","image":null}},{"node":{"id":"Question_11804-markdown","title":"Is there a definitive method to test for marijuana impairment during roadside checks?","slug":"is-there-a-definitive-method-to-test-for-marijuana-impairment-during-roadside-checks","content":"\n_____________________\nWhile there are tests to verify whether a person has marijuana in their system, there is no definitive roadside test law enforcement has to use to see \"how high\" a driver is.

There are a number of factors that contribute to how much THC is present in your body at any given time including how much body fat you have, how active your metabolism is, how often you consume cannabis and what you are consuming (flower, edibles, tinctures, concentrates).
