How to Pass a Drug Test at Home

The most reliable way to pass a drug test is to abstain from use and wait for the drug to clear from the body. However, you can try some home remedies if you have to submit a urine sample in the next few days. There are some therapies available for special types of tests, such as blood, hair, or saliva tests. You can also try some strategies to increase your chances of passing the test. Remember that you could lose your job or face legal or other penalties if found to be cheating, so it’s still best to avoid doing so.

Delay testing for as long as possible. Depending on the drug and how flexible the test is, you may want to delay until the drug is cleared from your system. Find out what the timeframe is for finding out what you’re using and try to delay as much as possible. Some substances have the following detection timeframes: ^{[1] X Research Source}

Alcohol: 2 to 96 hours
Amphetamine: 3 to 7 days
Cocaine: 24 to 96 hours
Cannabis: 2 to 84 days
Heroin: 48 to 96 hours
Opium: 3 to 7 days
PCP (angel dust): 3 to 14 days.

Want to know in advance whether you will pass the test? There are home drug test kits that you can use on the market. Remember that you may get different results depending on the time of day of the test. ^{[2] X Research Source}

Drink plenty of fluids in the days or weeks before the test. Water will help you get rid of the addictive substances in your body, but it takes time. Try to drink at least 8 cups (240 ml) of water each day for weeks before the test to help your body naturally detox. ^{[3] X Research Sources}

Carry a water bottle with you throughout the day and refill as needed.
Drink extra water on hot days and when you exercise a lot.

Stop using drugs as soon as you know about the test. If you have been told at least a few days in advance of the test, stop using the drug immediately to give your body time to clear it. Do not continue to use drugs in the days or weeks before the test. ^{[4] X Research Sources}

If you are concerned about withdrawal symptoms, go to the hospital or call your doctor. You may require a supervised medical detox if abstinence is not possible.

Pass the urine test

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/47/Pass-a-Drug-Test-With-Home-Remedies-Step-4-Version-3.jpg/v4- 728px-Pass-a-Drug-Test-With-Home-Remedies-Step-4-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/47/ Pass-a-Drug-Test-With-Home-Remedies-Step-4-Version-3.jpg/v4-728px-Pass-a-Drug-Test-With-Home-Remedies-Step-4-Version-3. jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}

Urinate at home in the morning on the day the sample is taken. Urine first thing in the morning will have the highest concentration of the substance because it has accumulated all night. Don’t come to the testing facility without urinating! Please pee before you leave the house. ^{[5] X Research Sources}

For example, if the test time is 9 a.m., get up at 7 a.m. and urinate right away.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/68/Pass-a-Drug-Test-With-Home-Remedies-Step-5-Version-3.jpg/v4- 728px-Pass-a-Drug-Test-With-Home-Remedies-Step-5-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/68/ Pass-a-Drug-Test-With-Home-Remedies-Step-5-Version-3.jpg/v4-728px-Pass-a-Drug-Test-With-Home-Remedies-Step-5-Version-3. jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}

Drink at least 700 ml of water within 2 hours before the test. Drinking plenty of fluids before a urine test is also known as a “cleanse” and is the most common method of passing a urine test when you don’t have much time to prepare. Start drinking water the morning of the test day or at least 2 hours before the sample is collected to increase the amount of fluid excreted and dilute the drug in the urine. ^{[6] X Research Sources}

For example, if the test is scheduled for 11am, start drinking water at 9am.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c1/Pass-a-Drug-Test-With-Home-Remedies-Step-6-Version-4.jpg/v4- 728px-Pass-a-Drug-Test-With-Home-Remedies-Step-6-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c1/ Pass-a-Drug-Test-With-Home-Remedies-Step-6-Version-4.jpg/v4-728px-Pass-a-Drug-Test-With-Home-Remedies-Step-6-Version-4. jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}

Take B-complex vitamins to darken urine color. When you drink a lot of water, your urine will be lighter in color, and this may cause the lab technician to suspect that you have been drinking a lot of water to dilute your urine. For camouflage, you can take a B-complex vitamin when you start drinking water. This will make your urine look darker and reduce the chance of you being suspected of being “purging”. ^{[7] X Research Sources}

For example, if you start drinking water at 9 a.m., take your B-complex vitamin at the same time.
You can buy vials of B-complex vitamins at drugstores.

Tip : If you don’t have time to run out to buy B-complex vitamins, you can take a multivitamin. This type also contains B vitamins, so it has the same effect.

Try taking an over-the-counter diuretic to increase fluid excretion. Taking an over-the-counter diuretic a few hours before the sample is taken can help thin the urine by increasing the amount of fluid excreted. Diuretics are available at most pharmacies. ^{[8] X Research Sources}

Do not exceed the recommended dosage! You must use according to the manufacturer’s instructions.
Coffee, tea, and kumquat juice also have a mild diuretic effect if you don’t want to go out and buy a diuretic.

Add Visine eye drops to urine if tested for cannabis. Although uncertain, one study found that a few drops of Visine eye drops in the urine reduced the concentration of THC in the urine. If you can collect a urine sample in a private room, add a few drops of Visine to your urine after the sample is collected. ^{[9] X Trusted Source PubMed Central Go to Source}

Make sure you’re not being tracked when doing this trick! If you are found to be lying, you will automatically be disqualified, and depending on the region, you may even get in trouble with the law.

Pass other drug tests

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/7b/Pass-a-Drug-Test-With-Home-Remedies-Step-9-Version-4.jpg/v4- 728px-Pass-a-Drug-Test-With-Home-Remedies-Step-9-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/7b/ Pass-a-Drug-Test-With-Home-Remedies-Step-9-Version-4.jpg/v4-728px-Pass-a-Drug-Test-With-Home-Remedies-Step-9-Version-4. jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}

Avoid drug use for 4 hours before a blood or saliva test. These tests are more sensitive than urine tests and are used to check the status at the present time. Blood and saliva testing is usually used when you are suspected of using drugs during working hours or being involved in a traffic accident. ^{[10] X Research Source}

Note that there is little you can do in the event of an immediate need to have a blood sample taken.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/77/Pass-a-Drug-Test-With-Home-Remedies-Step-10-Version-4.jpg/v4- 728px-Pass-a-Drug-Test-With-Home-Remedies-Step-10-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/77/ Pass-a-Drug-Test-With-Home-Remedies-Step-10-Version-4.jpg/v4-728px-Pass-a-Drug-Test-With-Home-Remedies-Step-10-Version-4. jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}

Eat, drink, and use mouthwash before taking a saliva sample. The more saliva you produce before the sample is taken, the better! Eat a meal or snack, drink several glasses of water, and rinse your mouth with mouthwash or with plenty of water if mouthwash is not available. This will remove the THC from the saliva, so it won’t be present in the saliva sample. ^{[11] X Research Source}

Tip : When it’s urgent, a stick of chewing gum in the mouth also helps remove THC from saliva.

Wash your hair with an anti-dandruff shampoo or a deep cleansing shampoo before taking the hair sample. These shampoos can help reduce the amount of detectable drug in hair follicles. If you are informed about the test in advance, purchase a bottle of anti-dandruff shampoo or deep cleansing shampoo and wash your hair 2-3 times on the day of the hair sample. ^{[12] X Research Source}

Note that this is not guaranteed to work. The hair follicle test is used to detect drug users within the past few months. If you used drugs during that time, you may still not pass the hair follicle test despite using this tip.

Find out if the drug you are taking can be detected by a drug test. The two main types of drug tests are the 5-panel test and the 10-panel test. The 5-panel test detects marijuana, cocaine, PCP (angel dust), opiates, and amphetamines. The 10-panel test screens for all of the same drugs as in the 5-panel test, plus benzodiazepines, oxycodone, methadone, barbiturates, and MDMA (aka ecstasy). If the drug you are taking is not one of the above, you will probably be safe. ^{[13] X Research Source}

Note that some employers may also test for alcohol if you are suspected of drinking on the job.
There are also screening tests for synthetic drugs, but these are not commonly used.

Tell the drug examiner about the prescription drugs you are taking. If you’re taking any prescription medication, tell the drug screening facility, especially if it’s from the drug class they’re testing. You will have to show proof, such as a doctor’s prescription. ^{[14] X Research Source}

For example, if you were ordered to take a 5-panel drug test and are taking amphetamines for attention deficit disorder (ADD), you need to let the lab know.

Avoid foods with poppy seeds. Poppy seeds can give a false-positive result in drug tests, because it is also the type of plant used to make opium. You should avoid eating poppy seed foods in the days and weeks before the test. Tell the testing site if this is a surprise test where you have previously eaten foods containing poppy seeds. You may be tested again if there is a false positive result. ^{[15] X Research Source}

Foods that may contain poppy seeds include some bagels, muffins, bread rolls, and muffins.

Stay away from untested or unsafe methods. There are many home remedies that claim to help get through a drug test, but very few of them actually work. Some methods are untested, and some are even dangerous, so don’t try! Things you must definitely avoid include: ^{[16] X Research Sources}

Drink golden ranunculus root (gpdensal root)
Add bleach, ammonia, or vinegar to your urine
Using synthetic urine
Drink bleach or other household cleaners.

Warning : Never drink bleach or any other household cleaner! This is very dangerous, even life-threatening!

Advice

The best way to pass the drug screening test is of course to stay off drugs long before the hiring process begins.

Warning

Attempting to cheat a drug test can be illegal with criminal/civil penalties, depending on the region. Consult your local laws if you are unsure.
Don’t try any therapy that requires swallowing dangerous things. Household cleaners are extremely dangerous to swallow, even fatal.
Note that drug screening blood tests are usually only used if your employer suspects you used drugs while on the job, and you could lose your job, regardless of whether you are found positive or not. refused to test. ^{[17] X Research Source}
