How to Pass a Drug Test in 24 Hours

Obviously, the best way to pass a drug test in 24 hours is to never use drugs in the first place. While this is the ideal, there are times when you need to pass a drug test quickly. Most drug tests that are given in the United States are urine tests. While hair and blood tests are used sometimes, most companies choose to use urine tests instead. These tests are far cheaper, and they can be bought at just about any grocery store or pharmacy.drug_test

Since you can buy a drug test at a store, you may want to consider investing in one first. This way, you will know immediately if you will be able to pass a drug test or not and what you should do next. If you are taking a drug test for marijuana, there are THC tests available for $1 at most dollar stores. Stock up on several of the tests and use them as you get closer to your real test date to see if you will have a problem.

As a rule, marijuana will appear on a drug test for at least five days after you have used it. If you are a habitual, regular user, then it can take months for the drug to leave your fat cells completely. Luckily, many drug tests are only done on urine, so you still have a chance of passing.

How to Pass a Drug Test

A drug test is a technical analysis that is done on your hair, sweat, urine, blood, breath or saliva to determine if you have been using drugs. For alcohol, breathalyzers are typically used when you are driving, although you can request a blood test in many states. If you have not been drinking for a while, requesting a blood test may give you just enough time for your BAC to drop below 0.08. If you have just consumed a significant quantity of alcohol, you should skip the blood test because your BAC is only going to increase in the near future.

Most government agencies and employers use a urine test because it is far cheaper, easier and more accurate than comparable tests. Drug tests may be done by employers to look for the presence of illegal drugs, or they may be done by professional sporting groups to check for performance enhancing drugs. Police officers may also perform a drug test to see if there is any alcohol or drugs present in the blood and the body.

What Are the Different Types of Drug Tests?

While a urine test is the most common, there are several different types of drug tests that can be used. Ideally, learn the type of drug test that you will be given in advance. This will allow you to know how much work you will need to do to pass the drug test in time. Some of the most common drug tests include:

Breath Test: The breathalyzer was first created in 1954. Since then, it has been used to test drivers for the presence of alcohol when they are driving. The individual breathes into the test with a deep exhale. Then, the machine shows how much alcohol is in their body. While police officers will tell you to breathe deeply before exhaling, this can actually raise your BAC. If you can, try to take shallow tests before breathing into the breathalyzer. In addition to the 1954-era breathalyzer, breath tests can all be done with fuel cell detectors and light absorption devices.

Urine Test: This is by far the most common way to test for drugs. You urinate in a cup that is given to a laboratory. At the lab, they test the urine with drugs. Basic at-home drug tests look similar to a pregnancy test and may be used by smaller companies or parents. A urine test does not show how much of the drug has been used in general. It only shows that the drug is present or not present in the urine.

Blood Test: This type of test uses the blood to tell if there are drugs in the body at that specific amount of time. Marijuana will immediately show up in a blood test six hours after it was last used. It can continue to appear within the blood test for about 30 days after marijuana was last used. These tests are by far the most accurate, but they are infrequently used due to their cost.

Hair, Sweat and Saliva: In theory, you can test for drugs in the hair, sweat and saliva. Since these options may be more costly or less accurate than other test forms, they are not used as frequently.



Alcohol Test: Other than testing the breath, alcohol can also be detected in your hair. The test looks for by-products of ethanol metabolism that are found in the hair.

Random Drug Testing: Many employers and sporting groups will use random drug tests to check for alcohol or drug use. These may be done at any time or day, so there is no real way to prepare for them. Often, a random drug test will be done if there has been an injury at work or if the individual recently had an unusually good sporting performance. Other behaviors like violence, agitation or aggression could also cause an employer to request a random drug test.

Presumptive Substance Training: Testing for every drug is not always easy or cost effective. Instead, some organizations choose to do a presumptive drug test. They train individuals to look for traces of drugs so that they do not have to test for every drug individually. It only takes a little of the drug to appear for the test to be run and determined.

Diagnostic Screening: This type of test is generally done if someone has been acting erratically or is unconscious. It can be also done after someone has died. Two samples are used from the blood and the urine to test the patient. Once the sample is done, the results take only 10 to 15 minutes to appear. It can be done during a post mortem for up to four days after the death has occurred.

How to Pass a Drug Test in 24 Hours

Now that you know the types of tests you can expect, the next step is to make sure that you will be able to pass your drug tests. If you have not already stopped using drugs or alcohol, you should stop immediately. The sooner you stop, the easier it will be for you to pass your drug test.



It is important to begin these home remedies as soon as possible. A failed drug test can severely impact your personal and professional life. Colleges and universities expect you to pass a drug test in order to play sports or be at the school. Employers want drug-free employees. If your driver’s license has been suspended, you may also need to pass a drug test to get it back. All of these reasons mean that you should do as much as possible to make sure that you are able to pass your drug test.

In the human body, THC (tetrahydrocannabinol) metabolizes in a certain way. THC metabolites are fat soluble. This means that they are stored within your fat cells over time. When you urinate, they leave your body. This process is fairly slow, so it can take weeks or longer for THC to naturally leave the body of a heavy user. Individuals who have used heavily or who are obese will need longer to get THC out of their bodies. Since the metabolites are disposed of in your urine, the tests are done to look for the metabolites.

There are several ways that you can speed up the process of removing THC and other drugs from your urine. The following steps can be used, but make sure that you are in good health before attempting any at-home care. Anyone with kidney disease, cardiovascular issues or other problems should talk to their doctor before trying any home remedy for passing a drug test.

Home Remedies for Passing a Drug Test

1. Diuretics

Diuretics are food products that cause your body to become dehydrated. This increases the amount of urine that leaves your body, so it will remove liquid from your fat cells. Drinks like apple cider vinegar, cranberry juice, ice tea, coffee and grape juice are natural diuretics. Foods like carrots, watermelon, tomatoes grapes, cabbage, berries, lettuce and oats are also diuretics. You can also buy diuretic teas and herbs at the store—look for detox tea blends that contain juniper berry or dandelion root.

2. Water

Drink plenty of water. If you have a high amount of water flooding through your body, it will help to flush out the THC metabolites. At the very least, water will help to dilute the amount of THC in your urine. You should drink at least one gallon every few hours as your test approaches to make sure that you will pass the test. THC metabolites are not actually able to dissolve in water though, so it will not actually flush all of them from your body—it will just dilute your urine and remove the amount that is being flushed away at the moment.

3. Exercise

If drug tests are a frequent problem for you, then you should spend some extra time exercising. THC is stored in your fat cells, so exercise will help you to reduce the amount of fat that you have. Plus, the sweating during exercise will help to flush out the THC in your body. Exercising is not the best option for a drug test tomorrow, but it will help if you have a drug test coming up in a few weeks.

4. B-Complex Multivitamins

B vitamins (especially Niacin) are known for helping to flush THC from your body. Be careful about this treatment though because too much niacin can make your skin appear flushed. If you have been drinking a lot of water to flush out THC< take a B-complex multivitamin about two hours before your test. This will help your urine turn back to a normal shade of yellow so that your excess water consumption is not as noticeable.

5. Eat Plenty of Fiber

Fiber is amazing for your body, but it can also help with drug tests. There are too main types of fiber: soluble and insoluble fiber. One type forms a gel in your stomach so that you remain fuller for longer. The other type binds with fat and cholesterol as it speeds out of your body. Since THC is released from your fat cells, fiber can help the metabolites speed through to the colon and out of your body. Plus, additional THC will leave your body in your stool.

6. Baking Soda

Some DIYers recommend using baking soda for a urine test. For this test, you would add three to five tablespoons of baking soda into a glass of water before drinking it. It can cause some side effects and is not perfectly effective, so be careful about this home remedy.

7. Vinegar

Some people also swear by vinegar because of its detoxification properties. If you want to use this trick, combine two tablespoons of vinegar, water and lemon juice in a cup and drink one to two glasses a day for the days before your urine test. Vinegar has a tendency to give you an upset stomach and side effects, so be careful about using this method as well.

At-Home Remedies From the Web

Water is by far the most useful, safest and easiest way to prepare for a urine test. Other than drinking water, there are other home remedies online that some users have said work for them. These remedies range in their effectiveness and safety, so be very careful about using them.

Niacin: Niacin is fairly effective and can be purchased over the counter at most grocery stores and pharmacies. You should not use more than recommended because some of the side effects of excessive niacin include vomiting, flushed skin and fainting.

Cranberry Juice: Cranberry juice is a natural diuretic that helps to release liquids and THC from your body. Have several big glasses of cranberry juice each day before you take your drug test.

Alcohol: As long as your test is not being done for alcohol, drinking alcohol can help to remove liquid from your body. It is a natural diuretic, but be careful about drinking too much.

Bleach: Some people say that mixing a little bleach in your urine test will make your results come back clean. This is generally not true, and the laboratory will most likely notice if there is bleach in the urine sample.

Creatine: Creatine helps as a diuretic, but it is not always safe to use creatine for extended periods of time. Make sure that you do not have any health conditions before trying this option.

Eye Drops: Some people say that you can put a few drops from an eye drop container into your urine test for it to come back fine. This is not true; do not do it.

For all of these remedies, you should really consider buying a cheap, dollar store drug test. By doing that, you can test and retest yourself before your big day to make sure that you will come up clean. If you are still getting positive results, keep using these home remedies, drink more water and exercise to make it easier for you to pass the test.

Home Remedies for Passing a Hair Drug Test

Since urine tests may only pick up drugs used in the last few weeks (and less if the user drank water or used home remedies to remove the drugs from their system), hair tests are growing increasingly popular. Once you use marijuana, it will show up in your hair growth within the next five days. From there, it is next to impossible to remove the drugs from your hair.

While it may be impossible to remove drugs from your hair, there are some home remedies that users swear by. If you have a hair drug test coming up, you may as well try these home remedies. In the best case scenario, they work. In the worst case scenario, you are still going to fail your drug test like you would have before. Obviously, one of the easiest options is to cut your hair off. This works better for guys, and you should cut your hair soon enough in advance for new strands to grow.

1. Rosemary Shampoo

To make a rosemary shampoo, heat up dried rosemary leaves with grapeseed oil for about three hours. Let the leaves and oil mix thoroughly together, but do not overheat the mixture. Afterward, strain the mixture into a clean container and let it cool overnight. On the next day, knead your scalp and hair until it is completely covered. Rosemary and the acids in the mixture may help to detoxify your hair.

2. Sea Salt

Salt is known for drawing out moisture, so it may help to draw out chemicals in your hair as well. Blend two parts baking soda to one part ocean salt and one part apple cider vinegar. Use the mixture on your hair and let it sit for up to seven minutes. Afterward, rinse the mixture off with a shampoo or cleanser.

3. Baking Soda

Blend baking soda and a couple of water droplets in your palm until it makes a glue-like paste. Next, knead this mixture into your hair and scalp. Afterward, mix some apple cider vinegar into warm water. Use this to wash your hair and rinse out the baking soda. According to believers in this remedy, the baking soda and apple cider vinegar will help to wash out the drug metabolites on the hair cuticles.

4. Lemon Juice

Add lemon juice to several cups of water before washing your hair with the mixture. Lemon juice is a natural detoxifier, so it is often used by people as a drink for cleansing their body. You can also drink water and lemon juice to help pass drug metabolites through your system before a drug test.

Home Remedies for Passing a Saliva Drug Test

Your spit will continue to have drug metabolites in it for three to four days after using drugs. A saliva test can be difficult to pass, so make sure that you do not use any drugs or alcohol for days before the test. If you can, wait as long as possible before you take the drug test. You may also try rinsing your mouth frequently with a lemon juice and water mixture or mouthwash. Keep in mind that mouthwash does have alcohol in it, so immediately using mouth wash before a saliva test could make you test positive for alcohol.

Tips and Warnings

You should never do anything that can effect your physical health. There are many drug test tips online that advise using harmful products like bleach on your body. This is not safe, and it will not help you to pass a drug test. If you have any medical conditions, it is important that you talk with your doctor before you start any home remedy. Use moderation when attempting these tests because even safe products like baking soda, apple cider vinegar, lemon juice or salt can be harmful in large amounts.

We strongly recommend that you do not use drugs. In addition to following the law, this is the safest, most effective way to pass a drug test. If it is already too late, there is also another alternative. There are head shops (tobacco stores) that sell fake urine. Currently, the fake urine appears the same on drug tests, so it can be used instead. This could change in the future, so make sure that your test cannot tell the difference between fake urine and real urine. The fake urine kits also contain hand warmers and squirting bottles so that the liquid is warmed up to body temperature before it enters the test cup.
