Maybe you work for a company that requires routine standard drug testing, or maybe a drug test is a legal condition for dealing with a problem. For testing, one can use a urine sample, hair, blood or saliva. Your personal and professional interests depend on a negative drug test result. Therefore, the best way to pass the test is to understand how long drugs are in your body and to stop using drugs for the appropriate period.

Steps

Method 1 of 4: Pass urine test

1. 

   Be aware that a urine test is the most common drug test. If your employer requests a drug test you will most likely need to provide a urine sample. Sometimes (more rarely) they will ask for blood, saliva, or hair tests. The urine test can be completed in private (in a lab bathroom) or supervised by a laboratory employee.

2. 

   
   
   Provides a list of the medicines you use. Drug testing confusion is very rare in accredited and reputable laboratories. However, certain prescription, over-the-counter and herbal drugs could be mistaken for narcotics in the examination. For example, some decongestants can lead to a positive result for a stimulant drug.To ensure that your drug test results are not false positive, you need to make a list of all medications you are taking and give it to your employer along with any required supporting documentation. .

3. 

   
   
   Know what substances will be tested through a device that tests 5 specific drugs. The urine test can detect a lot of substances in your body. The specific drug the employer chooses for testing depends on many factors: your personal history or your history / history, job requirements, legal advice or incident / accident. happened at work, and so on. However, devices that test the 5 most commonly used characteristic drugs are used. Most devices detect the following substances through urine tests:
   • Cannabinoid compounds
   • Cocaine
   • Drug
   • Phencyclidine (PCP)
   • The addictive substance has a stimulant effect

4. 

   
   
   Know what other drugs are tested as well. Although the 5 most commonly tested specific drugs are tested, some employers or legal workers may choose to add other drugs to their tests. They may further test for some or all of the following:
   • Alcohol contained
   • Ecstasy
   • Barbiturates (sedatives)
   • Propoxyphene (anesthetic pain reliever)
   • Benzodiazepines (mild sedatives)

5. 

   Understand the time drugs last in the body. A urine test does not check your alertness at the moment you give the sample. Instead, it checks your medication history over the past few days or even weeks. Regular drug users always have higher levels of the drug in the body than those who only use it occasionally. For this reason, drug addicts can produce a positive test result even if they have not used drugs for a few days or weeks. Other factors also affect the concentration of drugs in your body, such as your metabolism, the dosage and type of drugs you take, your hydration level and your overall health. However, in general, a urine test can detect these types of drugs for the following time:
   • The addictive substance has a stimulant effect: 2 days
   • Sedative: 2 days-3 weeks
   • Mild sedative: 3 days (therapeutic dose); 4-6 weeks (regular use)
   • Cocaine: 4 days
   • Ecstasy: 2 days
   • Heroin: 2 days
   • Cannabis: 2-7 days (for single use); 1-2 months or more (regular use)
   • Ice: 2 days
   • Mocfin: 2 days
   • PCP: 8-14 days (disposable); 30 days (heavy addicts)

6. 

   Stop using the drug for an appropriate amount of time. To pass the drug test, the only way that is likely to succeed is to not use the drug, especially during the examination phase. In some cases, you can know in advance when the test will start. However, for other cases, you may not be informed. Then, you need to consider whether your conditions are favorable for drug testing in the near future. For example, stop using the medicine at once if you:
   • Looking for work.
   • Being on probation.
   • Are in a profession that requires occasional unannounced drug testing.

7. 

   Do not attempt to add or change urine samples. This is the method used to deceive test equipment from certain results. Nitrogen-containing commercial and non-prescription chemicals were used to camouflage THC compounds (Tetrahydrocannabinol: the main ingredient in the cannabis plant) but are no longer effective today. Modern technology can detect them all and of course they fail the test.

8. 

   Do not try to dilute urine samples. Dilution is the process of reducing the concentration of a drug or drug metabolite in the urine by adding a solution to a test sample (some websites recommend this). However, drug testing laboratories always test urine samples to detect dilution.
   • One way to dilute the test sample is to add more water to the urine. However, when the test is done, the temperature of the sample is usually measured, so diluted urine is more easily detected.
   • Another way to dilute urine samples is to purify the body by drinking plenty of water. However, this can be dangerous (you could die from water intoxication) and is risky because colorless urine will raise suspicion and potentially be rejected. You may be asked to provide another test sample after a few hours and that is not enough time for your body to clear traces of the drug.

9. 

   Provide a sample when you have been drinking enough fluids and have urinated earlier in the day. Although very pale urine may lead to test failure, you can still slightly lower the THC concentration in your urine if you are hydrated. For people who haven't used marijuana for a few days, this can make a big difference in test results. To provide an optimal urine sample, you can:
   • Drink 3-4 glasses of water the morning of the test.
   • Urinate at least twice before giving the test sample. Early morning urine usually contains the highest drug content. Give your body time to get these out and never use your urine for the first time of the day as a test sample.
   • Drink coffee or caffeinated soda. Caffeine is a mild diuretic, which can help you to increase the amount of water you waste quickly.

10. 

    Exercise caution when replacing test samples. Swap is a method of replacing your test sample with someone else's urine or artificial urine. On the Internet there are many companies that sell devices for swapping artificial urine and urine samples.
    • Be cautious because changing urine samples could put you under legal prosecution. In many places, it can constitute a crime to replace your urine sample with someone else's urine. This is considered criminal fraud and you could put your job, career and legal status at risk. You should carefully consider whether it is worth the risk of swapping a urine test.
    • Artificial urine comes in two forms: a liquid sold in drug stores, similar to the substance used to measure the accuracy of laboratory equipment; or small bottles of powder with ingredients that can be mixed with a few ml of warm water. Both are stored in a special temperature-gauge container.
    • One of the difficulties in using surrogate samples is to keep urine samples at normal body temperature (32-36 ℃).
    • Some laboratories now also test artificial urine. For the sake of your legal rights, you should never use the urine replacement method for any state tests such as the military, the public service and especially the probation regime.
    • The drawback of liquid artificial urine is that there is no foam or small bubbles on the surface and no odor. Powdered artificial urine is available. Many laboratories will reject your test sample as well as ask you to provide it under direct supervision if they suspect it is artificial urine.
    • It is also risky to replace it with someone else's urine because they may not be able to pass the test either. The urine will also darken over time, bacteria multiply and damage the test sample. If the quality of the urine has deteriorated significantly, the laboratory may suspect it.

11. 

    It is not recommended to use the drug immediately after passing a urine test. In some cases, your employer or probationer may ask to have your urine tested again. So don't celebrate because of successful drug use tests: you might fail next time. Be patient and make sure your results are believed before taking any further action. advertisement

Method 2 of 4: Pass the hair follicle test

1. 

   You need to understand how the hair test works. When drug metabolites enter the bloodstream, they remain in the blood vessels, including those in the head.Traces of the drug are then analyzed through the hair and lead to a failure in the test.
   • Drug testing through a hair test can reveal which substances you have been taking for the past few months. Compared with a blood and urine test, this is the most suitable test to see if a person has been using drugs for a long time.
   • To test your hair, you need to cut about 50-80 strands of hair behind, close to the top of your head. Note that even though it is often called the "hair follicle" test, your skin will not be affected by the test.
   • The minimum sample length required for the test is about 3.5 cm of hair at the top of the head. If the hair is not long enough for the sample (such as the person who was examined to cut the tip of the nail), hairs in places such as the face, chest or arms may be used.

2. 

   Be aware that a hair test is less likely to detect if you are taking drugs only once. Hair follicle testing is more effective for long-term drug users or heavy addicts. If you have only taken drugs once in the past 3 months, you can secretly hope that you will pass the test. However, if you have been taking drugs on a regular basis every day, continuously for a period of time (perhaps a week) then you are likely to fail the test.

3. 

   Be aware that drugs take 5-7 days to get into your hair. Although the hair test has a very high chance of detecting drugs that have been previously used, drugs that have been used very recently will hardly be tested this way. It usually takes a few days to a week from the last use of the drug to get into your hair.
   • For this reason, some employers and agencies will ask you to do both a hair test (to detect long-term usage habits) and a urine test (to find out if you are taking medication. in a short time).

4. 

   Know which substances will be tested in the specific drug testing device. One of the most common hair follicle tests is the use of a device that tests the 5 specific drugs. As well as the 5 typical ointments tested for the urine test, traces of the following are detected through the hair:
   • Cannabis
   • Cocaine
   • Drug
   • Stimulants (including ecstasy, meth and Molly drugs)
   • PCP

5. 

   Know what other drugs may be tested. Some employers and legal agencies may choose to take drugs in addition to the 5 specific drugs for testing. These include drugs that are on many formulations of prescription drugs and also widely available at pharmacies. These include:
   • Mild sedatives
   • Methadone (anesthetic sleep medicine)
   • Barbiturates (sedatives)
   • Propoxyphene (anesthetic pain reliever)
   • Oxycontin (pain reliever)
   • Demerol (pain reliever)
   • Tramadol (pain reliever)

6. 

   Stop taking all medications 90 days before your test. In general, approximately 3.5 cm of hair on the top of the head (from the roots) will be taken for testing. This is enough to check your medication history for the previous 90 days. Therefore, the only way to definitely pass a hair test is to not use drugs during this time.

7. 

   You need to be careful because it is difficult to test your hair to fake it. The techniques used to deceive the urine test do not apply to the hair test. First, hair samples are usually taken directly by a lab assistant because there is no need for privacy concerns like with a urine test. The good thing is that there are no chemicals that can be hidden or any thinning method that can reduce the amount of toxins in the hair. And finally, temporarily stopping your medication is not enough for you to pass most hair follicle tests. Because of its very high success rate, hair tests are used by many employers and legal entities.
   • It is common for people with dark hair to deceive the hair follicle test. For this reason, there are many claims that hair testing is racist and ethnic.

8. 

   Be wary of special shampoos and dyes. On the market there are a number of shampoos that are thought to help you pass the form of hair test drug test. However, none of these substances have been scientifically recognized, any evidence of their effectiveness is rumored and highly questionable.
   • This trick is rumored to be successful: dip your hair in white vinegar, salicylic acid and bleach, followed by a temporary hair dye. This method has not been proven, but is also relatively inexpensive and as long as you don't get these chemicals in your eyes, they can cause side effects.
   • Some studies show that chemically treated hair shows less of cocaine.

Method 3 of 4: Pass the saliva test

1. 

   Know how the test works. Conventional oral saliva / fluid-based drug testing can detect substances used within a few hours to a few days before. This type of inspection is increasingly popular because of its convenience, non-intrusiveness and low cost. Saliva tests detect all medications in the blood.

2. 

   Understand the time of discovery. The saliva test can detect drugs for as long as you have just used them up to 4 days ago. However, many people taking mild drugs are still able to pass the test when they are sampled about 26-33 hours after use. For this reason, some people assume that the saliva test is edema. more suitable for reduced work capacity than in general drug-related behavior investigation. For this reason, personnel in industries that are involved in reduced work capacity (such as commercial transport companies) are often given saliva tests. The time of drug discovery is generally as follows:
   • Marijuana and hashish (THC): One hour after ingestion, sometimes up to 24 hours depending on usage.
   • Cocaine (including crack): From absorption until 2-3 days later.
   • Opium: From absorption until 2-3 days later.
   • Ice and ecstasy: From absorption until 2-3 days later.
   • Benzodiazepines: From absorption until 2-3 days later.

3. 

   Try to fast for 2-4 days before your exam. Most saliva tests usually take place in the laboratory, so it is difficult to swap or interfere with the test sample. Other than a urine test, this type of test is not invasive in privacy and this means you may be under supervision for the duration of the sample delivery. The only guaranteed way to pass testing is to stop taking the drug for 1-4 days before proceeding with the sample.

4. 

   Clean mouth with mouthwash, food or drink. Scientifically proven that eating, drinking, brushing teeth or using mouthwash all temporarily affect saliva test results. However, these effects go away after 30 minutes or more. Therefore, many agencies ask you not to eat or drink anything for half an hour before the test. During this time, you will likely be supervised by laboratory staff. But, if left unobserved, you are still likely to "survive" by cleaning your mouth with a commercial mouthwash. Don't get caught or they will ask for another saliva sample. advertisement

Method 4 of 4: Know common drug test cases

1. 

   Know when you will be supervised when checking. If you defer giving your driver's license while providing a test that has a temperature outside the acceptable range or shows signs that you have incubated for heat retention, etc., you will be asked to provide samples again under direct supervision. Some employers require that sampling take place under the supervision of an authorized person (doctor, nurse, etc.) of a person. a history of alcohol and drug abuse. You can of course always refuse to provide samples under supervision, but this puts you at risk of losing your job.

2. 

   Understand the law. In the United States, at least ten states (Arkansas, Illinois, Maryland, Nebraska, New Jersey, North Carolina, Oklahoma, Pennsylvania, South Carolina, Virginia, and Texas) have banned the sale of artificial urine or prototypes for Purpose to pass drug test. You should be cautious if you have this intention.

3. 

   Realize when you are likely to be tested. Currently, employers are legally authorized by law to require employees to undergo a urine test or saliva test in order to be admitted to work and / or not to lose their job. Provinces / municipalities have laws that often limit how and when the test can be completed, such as requiring the company to have a written policy, otherwise random inspection will not is applicable. However, there are still a few instances where you might be tested, including:
   • During the recruitment process. You do not have to undergo a blood test when applying for a job. However, potential candidates may have to pass drug tests as an indispensable condition of their job.
   • If you are a pregnant woman. In the US, some states require pregnant women to be screened for illegal drug use as part of prenatal care. Women who go to the hospital are given periodic blood tests. A pregnant mother is at risk for very severe or even more serious punishment if traces of drugs are found in her blood.
   • If you operate a vehicle or heavy machinery. Jobs where many lives could be put at risk if the employee is not sane — like the construction industry or the truck driver — often requires periodic disability checks. work.
   • When you display suspicious behavior. If you cause an accident at work, speak wildly or behave erratically, your employer has the right to ask you to receive drug testing as a condition of your job.

4. 

   Knowing when drug testing is not allowed. Laws are different from country to country and are changed frequently. You can find out about drug testing regulations in your area by looking up the labor code, contacting your local government, or expert employment regulation attorneys. You also have the right to examine your employees for drugs based on many factors. In the United States, drug testing is also influenced by the ADA (Americans with Disabilities Act), which includes the following key features:
   • The ADA does not allow an employer to examine a prospective employee without offering a conditional job offer.
   • The ADA also states that you must not discriminate against employees based on background drug problems in the past. Next, you have the right to refuse to hire a person if you have reason to believe they will repeat drug abuse or threaten the safety and well-being of other workers. If you don't know how to deal with a candidate with a history of drug addiction, talk to your business attorney. The ADA does not prohibit you from asking someone with a history of drug abuse to attend a rehabilitation program before joining your company.

5. 

   Know the right and wrong things about drug testing. There are many false rumors and unfounded claims about how to pass a drug test. There is also a large variety of commercial products that promise customers that they will pass the test without providing any evidence to back up these claims. The false information includes:
   • Passive smoking. Substance concentrations in the body are determined so that a person does not slip through unintentional inhalation of tobacco smoke.
   • Poppy seeds. In 1998, the recommended threshold was increased from 0.03 mg / L to 2 mg / L to rule out a false positive test result from poppy seeds. You will have to eat a whole loaf of poppy seed bread for positive results in just one day.
   • Bleach. Adding bleach to inactivate the urine sample will change the pH and raise a suspicion that the test sample has been tampered with and you could slip. It is also possible to take bleach and make you go blind and die.
   • Aspirin. Aspirin is thought to produce false negative results for THC. This just Effective under ideal conditions and certain types of tests. Nothing is certain.
   • Bleaching and dyeing will not remove the metabolites from the hair during the hair follicle examination. However, people with naturally blond hair are more likely to pass this test.

Advice

• By far the best way to pass the test is to stop using drugs. Although it is not possible to quit completely, stopping using drugs 1 week to 3 months before your test is likely to help you pass most tests.
• Be wary of most common drug testing possible cases. If you are working in a motor vehicle industry or operating heavy machinery, you may be tested more often. If you are looking for a job, many employers will ask you for a drug test when offering a job offer. Many people who are on probation or parole often get periodic drug testing.
• If you live in another country and use marijuana for medical purposes (prescribed by a doctor and not prohibited by law), talk to your private attorney about your options. Vietnamese law still does not permit the use of medical marijuana.

Warning

• Be extremely cautious when ordering miracle products online. Most of them are very expensive and have not been clinically proven. While there is some marginal evidence that these products are effective, there is no guarantee that these products are 100% guaranteed.
• Attempting to deceive test results can have serious personal and legal consequences and is seen as fraud in many countries.
• Do not use any harmful substances (such as bleach) to deceive the drug test. This is ineffective, and even very dangerous for your health.
• Do not drink too much water to pass the urine test. Your body will be hydrated with a moderate amount of water, but if you drink too much water, you will become poisoned. Besides being dangerous to the health, a urine sample found to be too dilute raises suspicion and you must provide another test sample.
