How to Pass a Drug Test in 24 Hours (Urine, Hair, Saliva, Blood)

How to pass a drug test in 24 hours

We’ve all been there: you’re wrapping up the interview for your dream job, and it’s going perfectly.  Until—record scratch—the interviewer says something like, “We’d like to extend the offer pending a required drug screen. Please report tomorrow for your drug test.” You smile confidently and agree, but on the inside—yikes! Fortunately, you have options available to you.  

If you have longer than just 24 hours to pass a drug test than your options become a lot wider and more accessible with a little more time. For some methods we'll discuss below, like how to pass a hair follicle drug test in 24 hours, are less damaging when you have a wider window for detoxification.

While it’s true that there’s no cleansing program that can totally cleanse all the fatty tissue of your body within 24 hours (the primary goal for passing a urinalysis, one of the most common drug screens), there are products available that can provide you with a small window of time during which you’ll test clean.

If you’re taking an unsupervised urinalysis, the solution is even simpler: use https://keytocannabis.com/products/test-clear-powdered-urine-kit-product-review to provide a guaranteed clean sample. There are even options for short-notice hair testing, which we’ll discuss in detail here. No matter what test you’re being subjected to, there’s a way to get clean in time!

Detoxing for a Drug Test: Know What You’re Up Against

In order to effectively detox the part of your system being tested, you’ll need to know what kind of test you’ll be subjected to. After all, clearing your blood won’t help you pass a urine screen, and flushing your system won’t save you from a hair follicle test. You’ll need to know what type of screening you’re up against before you can cleanse your system properly.

Sometimes it can be difficult to determine what type of drug test your potential employer plans on having you take. The majority of major businesses use the tried and true standard piss test to determine if THC is lingering in your body. A urine drug test is typically administered for a new job 75% of the time. After that typically comes hair follicle drug tests, blood tests, and at the bottom of the list, saliva drug tests.

With any of the detox methods, we’ll discuss below, it’s important to stop consuming cannabis immediately. It may seem obvious, but you want to keep from introducing any more THC molecules to your system, which could recontaminate you and lead to a positive result. 

How Long is THC Detectable in the Body?

How far out your drug test will be able to detect THC in your system is going to depend on the type of test. 

First Time User 1-2 Times a Month 3-5 Times a Week Daily Use
Urine Up to 1 Week 2 Weeks - 4 Weeks Up to 2 Months Up to 3 Months
Hair Unlikely 1 Week - 3 Months

How to Pass a Mouth Swab Drug Test In 24 Hours

A mouth swab is one of the easiest tests to pass, especially on short notice -- some mouth swag tests don't even test for THC! But, don't ask your administrator what the specific mouth swab drug test you're taking takes into consideration. That would seem a little suspicious, no?

Abstention for a day or two clears THC from saliva naturally and easily (provided you brush your teeth like normal!), but you can accelerate this process in a few ways: first, consume high-fat foods. THC is lipid-soluble, meaning it binds to fat molecules so fatty foods can help make THC make a quicker exit from your mouth.

Second, brush brush brush! You’ll want to combine good oral hygiene with vigorous mouthwashes (alcohol binds to THC as well, but be careful not to use an alcohol-based mouthwash right before the test!). To make sure you pass on short notice, use the https://keytocannabis.com/products/toxin-rid-rescue-wash-mouthwash-product-review (shown below) a few minutes before your swab for an extra layer of protection; it cleanses any lingering undesirable chemicals in time for a short-notice mouth swab.

How to Pass a Blood Drug Test In 24 Hours

Blood tests also have a fairly short window of detection, as THC usually only lasts for a few hours in the bloodstream. It’s also quite expensive and the sample needs to be sent off to a lab for testing, so for these reasons, it’s not a very popular drug test. That said, some companies do still use it (especially immediately following a workplace accident), and there’s a chance you could have to take one. 

Using a https://keytocannabis.com/products/toxin-rid-10-day-detox-program-product-review can help clear your system more quickly, though it helps if you have more than 24 hours to prepare. We like the https://keytocannabis.com/products/toxin-rid-10-day-detox-program-product-review as they all come with a Money Back Guarantee. As long as you have a full 24 hours to abstain, your blood will likely test clean—blood tests take a “snapshot” of the last few hours, but they don’t indicate habitual cannabis consumption. However, if you’re subjected to a blood test, you might be asked to take a urinalysis in conjunction with it (read on).

How to Pass a Urine Drug Test In 24 Hours

A short-notice urinalysis is enough to rattle any cannabis consumer, and it’s easy to see why: urine drug screens test not just for THC, but also its main metabolite, THC-COOH, an inactive form of THC. Using an antibody designed to bond with THC and THC-COOH, the immunoassay detects the chemical that gets you high, as well as its main metabolic byproduct. 

The bad news is, THC and THC-COOH can linger in the body’s fatty tissue (they’re lipid-soluble, remember?) for months in heavy cannabis consumers. This means that cleansing your tissue of all THC completely within 24 hours is, unfortunately, impossible. That said, there are two reliable ways to beat a urine screen with little to no notice. The first is the substitution method.

To use this method, purchase a https://keytocannabis.com/products/test-clear-powdered-urine-kit-product-review (shown in image below) and keep it on hand for a surprise drug test. Then, the day of your test, mix the powdered urine with water and use the included heater to warm it up to body temperature. The reusable temperature strip will let you know when your sample is between 90 and 100 degrees. Then, use this sample when it comes time for your test!  While this method only works for unsupervised drug tests, it is a surefire way to test clean every time.

If you have to take a supervised drug test, don’t fret: there’s still another option. You may not be able to totally cleanse your entire system, but you can give yourself a window of time during which you’ll test clean. Take https://keytocannabis.com/products/mega-clean-cleansing-drink-product-review (shown in image below) in its entirety about three hours before you’re scheduled to take the drug screen, then fill the empty bottle with water and drink that as well. If you have time the day before, take the included pre-cleanse pills with 16 oz of water each over six hours. However, avoid taking them within twelve hours of your test.

Keep drinking fluids in the hours leading up to the test (don’t overdo it, overly diluted samples are also a red flag, but do keep safely hydrated) and make sure the sample you provide for your test isn’t the first pee after drinking Mega Clean. Urinate as many times as you need to beforehand. https://keytocannabis.com/products/mega-clean-cleansing-drink-product-review is effective for five hours after consumption, with its peak effect after three hours, giving you a moderately flexible window during which you can test clean. 

Passing a Hair Follicle Drug Test in 24 Hours

Since hair tests go back so far (the period tested is only about 90 days worth of hair, but it could theoretically be tested all the way to the ends of the hair shaft) and have such a low threshold for detection, they’re notoriously hard to beat. That said, you do have some options, though we should warn you that your hair will hate you for what we’re about to recommend.

First of all, you’ll need to get a cleansing shampoo like https://keytocannabis.com/products/old-style-aloe-toxin-rid-shampoo-product-review or https://keytocannabis.com/products/zydot-ultra-clean-shampoo-product-review (we highly recommend the combination of both: Toxin Rid before, and Zydot to finish). The three-part cleansing system of Zydot makes for a good final deep clean before the test and restores some strength and shine to the hair, which will be quite dry after all is said and done.  

We recommend washing your hair at least 10-15 times with the https://keytocannabis.com/products/old-style-aloe-toxin-rid-shampoo-product-review, perhaps supplementing with a https://keytocannabis.com/products/zydot-ultra-clean-shampoo-product-review every 5 washes or so, before you’re due to test. It sounds extreme, but it works. You’ll need to let the shampoo sit on your scalp for about 15 minutes each time before vigorously scrubbing to remove oils and other molecules from the hair shaft. Focus on the scalp, where oils tend to remain.

You can also supplement with vinegar rinses, salicylic acid acne treatments, even detergent washes (your hair won’t like it at all, but it will help). You can also use a bleach or box dye that includes peroxide developer to help remove excess THC, though it would take multiple processes to remove everything through this method. It’s important to avoid re-contamination by contact with things like hairbrushes, linens, and hats that were used on your un-cleansed head. Change all your linens, wash hats, and perhaps get a new hairbrush just for this purpose.

A Quick Note About Drug Testing

If drug testing is a part of the conditions of your employment, you might be concerned about the potential of CBD to cause you to test positive for THC. This isn't an unfounded concern -- however, there isn't exactly a cut-and-dry way to answer it.

Much of the data we have about CBD is anecdotal, and its potential impact on drug testing is no exception.  There are very few peer-reviewed studies on the subject, and the ones available paint a rather murky picture:  avoiding full-spectrum products containing traces of THC can reduce your risk of a false positive, but that may not eliminate the risk entirely.  A single study (as yet unconfirmed) suggests that even isolate-based products may not be completely risk-free under certain circumstances.

If you are concerned about passing a drug test, you’ll need to consider this potential risk when deciding whether CBD is right for you. To learn more about the science of CBD and drug testing, check out our article for a more thorough discussion of how to minimize your risk of a false positive.

Conclusion

There are a number of ways to pass a drug test on short notice, especially if you’re prepared.
