Niacin Flush Detox Method

Niacin Flush for Drug Detox

With drug testing beginning to rise in popularity as a workplace standard, people are starting to look for more and more efficient ways to quickly cleanse their bodies of substances that could make them test positive.

Taking niacin has long been a known detox method, but its effectiveness has always been a topic of debate.

What is Niacin?

Niacin, otherwise known as Vitamin B3 is compound naturally found in a human body that serves the purpose of metabolizing carbohydrates. When it comes to niacin for drug testing, it is usually talked about niacin pills that can be bought in pretty much any pharmacy.

Niacin pills are usually used as a dietary supplement for people who are suffering from high cholesterol levels or low niacin levels, but it is also often used to increase the health of skin, hair and eyes. A niacin pill has around 500mg of niacin in it and the recommended daily dose is up to 2000mg, to prevent the occurrence of negative side effects.

Negative Side Effects of Niacin Pills

  1. Skin flushing
  2. Burning sensation
  3. Swelling
  4. Reddening of skin
  5. Skin lesions or hives
  6. Diarrhea

Niacin Flush

Niacin flush is a method that has been argued to allow a person to successfully clear out traces of metabolites from their body in a shorter amount of time than usual. This is done by increasing the rate at which body breaks down fats, which is where metabolites usually tend to deposit, which in turn allows the person to pass the drug test even though just a short period of time has passed since their last drug use.

The problem with this method is that niacin pills have varying levels of effectiveness from person to person, depending on their height and weight, as well as their metabolism rate. People with higher than average body fat content have reported this method to fail more often than people with lower body fat content.

Another thing to note about this method is that it is not a miracle solution like some people claim and that it has to be done over a period of time, preferably 2 – 5 days for maximum efficiency. This is due to the fact that niacin is very hard on one’s liver and taking large amounts of it (more than 500mg) at once poses a serious health risk.

On the other hand, if the person using this method properly spaces out their dosage (500mg or one pill every 6 hours for 3 or more days) and hydrates plentifully, they pass the drug test in 80% of the reports.

By following this routine, you will be able to successfully cleanse your body from metabolites in 3 – 5 days so plan accordingly:

  1. Immediately after getting up, take 500mg of niacin and drink at least 2 large glasses of water.
  2. Wait a few minutes and try to urinate as much as possible.
  3. Eat a light breakfast, since fatty foods will reduce the effectiveness of niacin and preferably take a caffeinated drink to help you urinate more.
  4. During the day, try to drink water, fruit juice or sports drinks as often as possible, but make sure not to overhydrate yourself and get sick. Stay away from alcohol as much as possible.
  5. Take niacin pills every 5 or 6 hours with 2 large glasses of water, preferably before meals and try to urinate between niacin intake and meals.
  6. On the day of the test make sure to take at least two pills before the test itself and try to urinate as much as you can.
  7. If you notice your urine is discolored (not yellow), take a B12 pill; a discoloration of urine can be a clear sign that you have tried to dilute it and will raise suspicion.

If Taking Niacin Pills

  • Always space them out at least 5 hours to prevent overdosing.
  • Drink a lot of water, preferably two full glasses with every pill. Also drink as much water, fruit juice, sports drinks or caffeinated drinks during the day, but be careful not to overhydrate yourself.
  • Abstain from drugs and alcohol, to prevent negating the effect of niacin pills.
  • Eat light meals and stay away from fatty foods.
  • On the day of the test make sure to take at least two pills and drink 4 to 5 glasses of water.
  • If your urine starts to dilute too much from hydration, consider taking vitamin B12 pill as it turns urine yellow.
  • Try to urinate as much as possible during the process and especially before the test.
  • Bear in mind that taking niacin pills will only have an effect on a urine drug test; all other drug tests are unaffected by niacin intake.

Conclusion

Despite the fact that many people claim that this method does not work, it usually stems from the fact that the amount of time that the pills were taken for was not sufficient. Taking a large dose of niacin pills in a short period of time, just before a drug test, will more often cause serious health problems then help pass said test. Only by giving it time will this method have the expected effect without the negative consequences.

  • So on the day of the test take 1000 ml ??

    • No, clearly it states take 1 (500mg) every six hours before a meal with two large glasses of water.

    • Yes but try spacing it out so it’s not too harsh on your liver

      • Hello i recently just passed a urine drug test using the niacin method took them everyday for a week straight drank a lot of water and minimal exercise my only concern is does the niacin PERMANTLEY rid the THC or MASK it? The test is a very sensitive lab test for probation the cut off level is 50 ng but someone in my case i HAVE to test at 0 ng to test negative. My drug tests are random meaning once a week so thats why i need to know if im permantley thc free. There was no drugs found in me so im guessing i’m at 0 ng. Was it the niacin and like i said am i permantley thc free? I only did the niacin after being clean for 4 weeks and my levels were dropping VERY VERY slow. Also, does the brand matter? I passed using the flush free reading online they say it doesnt work but it worked for me so to be safe i bought real niacin the Nicotonic Acid that actually gives you the flush. Thank you! Please reply!!!

        • Dude it does work huh? Imma have to use this method again over probably a span of a week or less time so I wont have to overdose and flush ya kno?.. But will you experience the flush every time Or; is there a more subtle way to take 100mg every 2 hours for 24 hours? Should probably be less harsh on the bladder system. Idk I go for mine in 72 hours so I have a jump start on the hydration regiment.

        • If your average weight and a regular smoker, youd be clean after 4 weeks even without the niacin.

          • This may be true for some people but not all. I’m 5’4 139lbs. I smoked regularly for 1 month and stopped. I haven’t smoked in 2 months and 2 weeks now. Was tested at work and failed test bc there is still THC in system. I knew that it couldn’t be true bc of the length of time I’ve been clean so I took 3 at home tests and all were positive. Time needed for THC removal varies by person.

        • Hi! Did you use anything in addition to the Niacin to cleanse your body of TCH?

    • Yes, nevermind Molly because she can clearly not read. Lol

  • this does work take for thee days i do it all the time

  • I have to do a test on 12 October please help me pass this test you guys I am trying to flush the THC out of my system do I have time I have niacin pills and I am starting to drink a lot of water now

    • How did your test go?

    • Everyone needs to know that THC stays in your system at least 30 days so if your looking for niacin flush to help stop right here cause u will still test negatively. Anyone that needs help to clean themselves from opium and cocaine can usually get clean in 3-4 days

  • Don’t do drugs in the first place.

  • Hello, I’m looking for suggestions to clean my system of Adderall. I’m on probation and the judge is Making me go cold turkey on all control substance.

    I drink 4-5 12oz bottles of propell a day.
    HELP ME PASS

  • Yes this method works and you need to start 3 days before the urine test at the absolute latest. If you try to do it two days before, one day before, or the day of, it will not work. Ive done this many many times and it’s always worked for me. But one time I got cocky and tired waiting 1 day before my drug test and I failed. I’d recommend starting 7 days before if you get tested on the same day every month.

  • Ues Madie it said take 1000 mg. the day of the test.

  • Niacin really works I smoked on Sunday and passed a test on Tuesday drinking lots of water and did a little bit of exercise and it probably took 9 pills of niacin spaced out overtime not all at once drinking a gallon of water before the test and urinating first don’t pee into the cup right away halfway then and then pee in the cup but I think the most important part is drinking a large amount of water but this is something I don’t recommend doing every week or month

  • I use niacin a lot to pass urine drug tests. It can be hard o. Your body but if you take enough for a week to ten days it will work. I am a heavy marijuana smoker. I stopped smoking 14 days before the test and took 3000mg of niacin for ten days straight. 1500mg at a time. It works well but make sure you drink LOTS of water just to be safe.

  • Will it help me pass a drug test today?

  • Will Niacin work if I mix it with Palo Azul? I test in 11 days. Eeek

  • This is exactly what I’m doing bro! Your making me feel so confident. I’m also taking mens multi vitamins with anti oxidants. I have a job interview/drug test on November 12th, and have not been smoking sense October 17th. I take 1500 mg a time, twice a day morning, and evening. I will continue the process until the day of my test, then will take a b12 vitamins to change my pee from highlighter greenish yellow, to normal yellow
    Wish me luck!

  • Interested in trying to clear Gabapentin from my system. This is a lab urine screen and it detects ANY amount of drugs in the system.

So, anyone know if this method will work for pills?

  • I was 35 days clean when I took my drug test. Oct 8th was my last hit. They says I had “high levels ” of marijuana. Test was on Nov 14th. I was a daily user mostly at night. They are going to random test with in the next 90 days, but again it will be random. I recently had surgery and have no weight barring fro 6 wks so exercising makes it
    hard. If I start the niacin process now taking a little each day with plenty of water, do you think I will be clean?

  • Has anyone tried this for employment at the post office ?

  • From my experience…you have to buy the regular niacin. Not the FLUSH FREE niacin. Theres 2 kinds. You can get this at most pharmacies.

  • So, I took the test yesterday and apparently it came back “clear” and I have been asked to take it again in the morning and not to drink anything before hand. I am I good because I took a home test yesterday morning and it came up negative but I probably drank too much water before the test?

  • I’ve been on probation for almost 6 years now and have done hours upon hours of research for passing a drug test after smoking weed; I’m here to give some insight to the ignorant. DO NOT exercise for up to 72 hours before your dt because it will burn the fat containing thc into your blood stream and your test levels will come back higher than if you were to not exercise at all. Also, drinking water does not matter up until the day before and day of drug test; all it does is dilute your piss so you’re pissing almost straight water so it’s useless to torture yourself until day before and day of by consuming gallons of water. I do recommend drinking as much water as you can and pissing at least 2-3 times before going in for your dt on the day of. I have tried niacin before and it worked once and didn’t work another time so this will be my third time trying out these methods. I believe you need to start consuming a minimum of 3 days before test for it to be able to be effective. I hope this was helpful to some people and best of luck on all your test(s).

  • I smoked a rello Friday night and have a urine Friday at 3pm I’m just finding out today, if I take 1 every 5 hours only twice a day will I be clean by friday at 3? I’m 5’6 120lbs

  • My drug test is on Thursday December 13th. I haven’t used cocaine since last Thursday night/Friday morning. I’m a regular marijuana smoker cause I have the medical card, but, I obviously don’t want to come up positive for the cocaine. I just took an over the counter test and the negative line was very dim. I right away took 10 niacin and chugged water. Then, started reading these comments. Do you think I’ll be ok to pass the test if I keep up with the correct doses of niacin and water?
