Heroin is one of the most commonly abused opiates. It has no medical purpose. If you've been abusing heroin or know someone who does, it always makes sense to learn a bit more about how it works and affects your body. The knowledge about its function and effects will help make better decisions about recovery. One of the most important things to know is, "How long does heroin stay in your system?" This important piece of information will really help you make important decisions, especially when you're in situations where drug testing is conducted privately. 


How Long Does Heroin Stay in Your System?

As mentioned already, heroin is an opiate, which means it will enter your bloodstream quickly and start building up in fat tissue. It is important to point out that drugs accumulated in your fat tissue will enter your bloodstream slowly over time. It is due to this particular reason that you notice the high remnant from heroin lasts longer than many other drugs. On the other hand, it implies that heroin will remain detectable a lot longer than many other drugs. Its quantity may be too low sometimes to show up on drug tests.

Here are some of the tests normally performed to check the presence of heroin in your system:

  • Urinalysis: It's probably the most popular way to check if there is heroin in your system or not. It is important to mention that heroin may show up on a urine test for as long as 2 days or it may not be detectable after a couple of hours. Heavy users may end up getting a positive drug test even after 7 days.

  • Hair follicles: Testing hair follicles is an increasingly popular way of testing for heroin use. It can help detect the drug abuse even after several months of use. Heroin and some other drugs have the ability to stay in your hair for up to 3 months or so.

  • Blood: You may have to undergo a blood test to confirm if you have used heroin or not. This is the least reliable method though because heroin and some other opiates leave your bloodstream in 6 hours or so.

  • Saliva: It is an effective test but has a short detection time. Heroin may not be detectable after 5 hours through this test. The test is more effective when the person has taken a large dose or has been using it for a while now.


Factors That Affect the Duration of Heroin in Your Body

How long does heroin stay in your system if you smoke it? The answer usually depends on the test used for detection. It may stay in your saliva for 5 hours and take 6 hours to leave your bloodstream. It is important to consider some other factors that affect the duration of opiate in your body as well.

  • Your height and weight will have an impact on the answer of "How long does heroin stay in system?" Your body size actually determines how much heroin you need to smoke to get high. When you use it in higher doses, it will stay in your system longer as well.

  • How much heroin you smoke will also determine how long it takes heroin to leave your system. The more you smoke, the longer it stays in your system. Sometimes, more potent heroin will stay longer in your system even if you smoke a little only.

  • The speed of your metabolism will also have an impact on how long it stays in your body. It will leave your body faster if you exercise and have a faster metabolism.


How to Speed Up the Processing of Heroin

Now, you already know, "How long does heroin stay in system?" This is time to understand what you can do to speed up the processing of heroin and make it leave your system faster. Here's what you can do about it.

  • Drink plenty of water. It's simple – water can flush your system out and it will help eliminate traces of heroin present in your body. It works well also because heroin will dissolve in water, which means it will soak up the drug and help it go out of your system through urine.

  • Exercise regularly. Regular exercise will help boost your metabolism. With stronger metabolism, it will be easier to detoxify your body after smoking heroin. Exercise also plays a role in burning fat, which means heroin will have little fat to hold onto. Make sure to do aerobic exercise at least twice a day for half an hour every day.

  • Detox. Exercise will help with detoxification, but you may have to use other ways to detoxify. It becomes even difficult when you're dependent on heroin for some time. The withdrawal effects can be serious, and only a professional help handle things better. You can also reach out for help if you struggle with heroin or any other drug.

    Also these metabolites are very quickly broken down,a positive opiate test should always demonstrate the metabolite present eg 6-MAM other wise it could be a false positive caused by ingestion of codeine, morphine or even if enough are consumed poppy seeds. (It's unlikely a poppy seed bagel will leave enough opiate to effect a test, but has been documented)

    Hi, good article but one glaring mistake, heroin does have a very established place in medicine, it is a potent analgesic and is used in trauma (EXCLUDING SUSPECTED HEAD INJURY) and as first line pain relief for heart attack patients, sold under its medical names the most popular being Diamorphine, Diacetylmorphine. Used via IV as route of administration it has advantages over morphine. Different types of heroin leave different metabolites demonstrating use of Heroin and unique to heroin. EXAMPLE heroin from the Afghan region is heroin type 6 and leaves 6-Monoacetylmorphine following use. These metabolites are often used to establish positive results for testing purposes as no other opiate will leave this metabolite. Other metabolites are unique to heroin from other regions.

    Jo-Jo I was using heroine for a while, around 2 bags a day. I used last on Friday evening at 10 pm as i was to receive a oral swab test on Monday afternoon. I drank plenty of water, exercised and done a tea detox. I had bought a saliva test off the internet to test myself before attending my appointment on Monday and it tested negative. i am worried that the test used at my work is more advanced than the instant result one that i purchased as they send it to a lab to test. Are my worries warranted or do you think i will be ok. If anyone could give me an answer to this it would put my mind at ease and would be much appreciated.

    I think because of the usage intervals that you are a steady user. This means that it may stay a bit longer I'm your urine... Also... The testing that they are using today are lowered ...meaning that they detect lesser levels therefore it takes longer to get out... If you keep coming up dirty and you know when the test is going to be you need to allow more time before the test... Definitely drink as much water as you can...You can always give someone else's urine that's clean but if it's supervised urine your gonna have to try and pull it off I doubt highly that your doing un supervised ones because you can drop a whole host of things that would come back clean.. In any event good luck and take care. Sincerely.. Almost 40 days clean here.. ..

    @ : OK: I dont use H very often, but the other day (about 3 days ago) i used a small amount and slammed it. Now i read that it can be undetected after 5 hrs depending on how often you use. And then today i had an oral swab, the cotton fell off and i squeezed the saliva out, he told me to keep it under my toungue or it would mess with the results so i did exactly NOT that. I drank a bunch of water and left a little in my mouth. So am i ok? i dont plan to go back to that doctor, However not thinking i was going to be able to see another doc i had one little quick fix and i dont know if im going to be tested again tomorrow. So, my question is, how can i possibly beat this with a home remedy? i heard that Listerine works if i can say the other test was a false positive and offer it up. Please help if you have any information that can help me. Thanks :)
