Does Niacin Work for Passing Drug Tests?
Here’s What We Found

Drinking niacin to pass drug tests

Do you need to pass a drug test but have low chances of doing so?

While we don’t encourage drug usage or altering test results, we still want to ensure you’re doing so in the healthiest way possible.

Some people swear by the niacin flush method. We’ll give you guidelines on how to apply it with your health in mind.

Niacin is a water-soluble vitamin—vitamin B3, an important nutrient for your body.

Taking the appropriate dose of niacin has multiple health benefits, like improved cholesterol and brain function.

In fact, niacin deficiency may result in a number of negative side effects, such as:

  • Pellagra (“rough skin”)
  • Memory loss
  • Depression
  • Headaches
  • Vomiting
  • Fatigue

Many people also apply the niacin flush method for detox purposes before drug screening and testing. This is because niacin burns fat and, consequently, may remove THC from your body.

Though the vitamin is FDA-approved, it appears in many supplements that are not well regulated[1].

Such supplements may contain more niacin than the recommended dosage (14-16mg/day for adults).

Niacin Pills

On that note, pills usually contain a very high dose of niacin—about 500mg per pill.

If you’re considering taking niacin pills before your drug testing, be extra careful.

Don’t use it for too long because you might experience negative symptoms or show signs of detox during your drug testing.

Does the Method Work For All Narcotics?

For now, we’re not even sure if it works for weed detox, let alone if you’ve used something stronger.

Our advice is based on people’s reports and anecdotal evidence. Please keep that in mind while reading.

Before you decide whether pills are the right solution for you, consider possible negative effects on your health, which include:

  • Skin flushing
  • Liver damage
  • Indigestion
  • Swelling
  • Skin lesions

While facial flushing typically lasts for up to half an hour after digesting niacin pills, other side effects can be long-term.

Using niacin for a longer time or in a higher dosage than the one that’s recommended can cause other symptoms too:

  • Panic attacks
  • Indigestion
  • Itching
  • Diarrhea
  • Abdominal pain
  • Rapid heartbeat

If you notice any symptoms, consult with a medical professional and be open about taking niacin pills for your drug testing.

Flush Vs Flush-Free Method: Which Should You Choose?

If your goal is to pass a drug test, you should opt for the flush method.

Flush-free pills won’t burn your body fat faster, which means they also won’t rid your system of traces of THC faster.

For now, there’s no conclusive evidence that flush pills will help you do so, but many people swear by this method.

Also, according to some sources, proper niacin usage helped 80% of test-takers pass the test:

“...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.”

  1. Stay away from narcotics for at least a week before your drug testing.
  2. Drink a lot of water and make sure you stay hydrated at all times.
  3. Space out your pills. Wait at least five hours before taking another one.
  4. Pee regularly—this will help cleanse your body faster.
  5. Don’t overdo it. Five days should be enough to rid any traces of drug use from your system.
  6. Make sure you’ve stopped showing symptoms by the time you need to undergo drug testing.

FAQs

For how long should I apply the niacin method before my drug test?

Apply this method for 2-5 days before your drug test to ensure you pass. If you used narcotics for a longer time, then it might take longer to work.

How fast can niacin clean my system?

Some people reported that they noticed benefits within only a few hours of taking niacin but it usually depends on three things:

  • your body mass and content
  • the drugs you have in your system
  • how many pills you’ve taken.

Will my urine indicate that I took niacin?

No. After all, niacin is not illegal—but signs of detox may get you into trouble, so keep that in mind.

Where can I buy niacin?

Since niacin is nothing but vitamin B3, you should be able to find it in grocery stores, supermarkets, and pharmacies.

Does niacin help with other types of drug tests too?

It might help with blood tests but probably won’t work for a saliva test.

The Verdict: Can Niacin Help You Pass a Drug Test?

While a lot of people swear by niacin’s ability to alter drug test results, there’s still no scientific evidence that would prove these claims. It also depends on which drugs you used, to what extent, and for how long.

The best way to ensure good results is, of course, to abstain from narcotics for a longer period of time.

But if you don’t have enough time, this method might help you. We still encourage you to consult with your doctor and disclose what you’ve used in the past.

He could tell you what’s the appropriate dosage according to your body fat content or at least advise you on other, healthier methods.
