Drug addiction remains a major issue in every country. Despite all the efforts that the government is making to prevent further damage, several drug manufacturers and distributors continue to find ways to continue with their illegal business. This is why drug testing has evolved as a precautionary measure to minimize the impact of substance abuse.
The following are some of the commonly asked questions and answers about drug testing:
There are many different types of drug tests. TestCountry sells instant urine and saliva tests, plus laboratory drug testing service and hair drug tests.
Choosing the best type of test for your purposes will depend on many variables, including your budget, how far back in time the drug test needs to detect usage for and if you need the results instantly or can wait for them. TestCountry’s knowledgeable staff can help you choose the best drug tests for your purposes.
Urine drug testing is one of the most popular methods of random drug testing for recent drug use, as they are easy to use and provide fast and accurate results. This method can detect the presence of drugs in urine from 1 day up to 7 days after the drug has entered a person's system. The big advantage to urine drug testing is that you have the ability to test up to 14 different drugs at one time.
Advantages:
Disadvantages:
Although opiates are derived from the poppy plant and eating poppy seeds does cause your body to produce opiate metabolites, it is not possible for eating food containing poppy seeds to produce a false positive on a drug test. This is because sensitivity standards were raised in the year 2000 from 300 ng/ml to 2000 ng/ml OPI to eliminate the possibility of false positive results from consumption of large quantities of poppy seeds.
No. Concentrations of THC metabolites above the cutoff sensitivity level of the test, which would give a positive result, are not possible by exposure to secondhand smoke.
No. The tests are drug and drug metabolite specific. Because these commonly ingested substances are chemically and structurally different after metabolized by the body from the drugs being tested for, they will not interfere with or compromise test results. Cigarette smoke and chewing gum have been known to interfere with saliva test results. Every test comes with clear instructions, though, on how best to perform the test to avoid false positives or invalid results.
Specimens can be stored if refrigerated at 2° - 8° C for up to two (2) days (48 hours) or frozen at 0° C or below, before testing. It is strongly recommended to test the sample as soon as possible after collection. For samples that have to be shipped to a laboratory, it is best to ship them immediately after they are taken.
The table below indicates the standardized threshold concentration levels for lateral flow immunoassay tests established by regulating authorities like the World Health Organization (WHO), the Substance Abuse and Mental Health Services Administration (SAMHSA) and the National Institute on Drug Abuse (NIDA). These levels are reviewed and updated periodically throughout SAMHSA drug testing locations to conform to new data on drug development, technology, and testing statistics. Concentration is expressed in nanograms per milliliter solution (ng/ml).
| Abbreviation | Drug/Metabolite | Cutoff Level |
|---|---|---|
| AMP | Amphetamine | 1000 ng/mL |
| BAR | Barbiturates | 300 ng/mL |
| BZO | Benzodiazepines | 300 ng/mL |
| COC | Cocaine/Benzoylecgonine | 300 ng/mL |
| mAMP | Methamphetamine | 1000 ng/mL |
| MDMA | Ecstasy | 500 ng/mL |
| MTD | Methadone | 300 ng/mL |
| OPI | Opiates/Morphine | 2000 ng/mL |
| OXY | Oxycodone | 100 ng/mL |
| PCP | Phencyclidine | 25 ng/mL |
| PPX | Propoxyphene | 300 ng/mL |
| THC | Marijuana/Cannabis | 50 ng/mL |
TestCountry is proud to offer our DrugConfirm Advanced Drug Test Cups that offer detection cutoff levels that align with SAMHSA & NIDA requirements. These tests range from our 5 Panel Drug Test all the way up to our 14 Panel Drug Test. 
Immunoassays are antibodies that specifically bind to drugs and their metabolites in urine and other bodily fluids. If a person smokes marijuana, for example, his body metabolizes the drug, which leaves behind the tell-tale compounds in his urine, blood, sweat, hair, etc. When he takes a drug test and his urine is mixed with a reagent (something that is added to the urine to bring about a chemical reaction) the reagent reacts with the metabolites in his urine and tells the tester that he has smoked marijuana.
Gas chromatography and mass spectrometry (GC/MS), another phrase you’ll hear often in terms of drug testing, are analytical techniques used in laboratory settings and that need laboratory equipment to be performed.
Gas chromatography and mass spectrometry can determine the presence of drugs and other substances and are often used to confirm the positive results from immunoassay drug tests. When you make an appointment through TestCountry for a laboratory drug test, these are generally the techniques that will be used on samples taken. Corporate drug tests are performed exclusively in SAMHSA drug testing locations. The same applies if you're searching for where to do EtG drug testing.
Codeine is a commonly prescribed opioid pain medication and also the active ingredient in some prescription cough medicines. Meperidine is structurally related to morphine and can cause false positive test results for morphine, heroin or other opiates. Codeine can also be addictive and is often abused either by itself or alongside other opiates.
Approximately 98% of the time, inconclusive test results or failure to obtain usable test results is the result of user error like failure to follow instructions, inadequate sampling, device contamination, failure to use a timer or other user-related factor. This is why it is critically important to read through the instructions completely before beginning the test and then follow them exactly while doing the test. People often expect the testing devices to be accurate regardless of how they are used.
Yes. Prescription drugs, if they fall into the class of drug being tested for, will cause a positive test. For example, if a prescription drug is classified as an opiate and you take a drug test that is meant to detect opiates, your prescription drug will cause a positive result on the test. You can find general classifications of prescription drugs by asking your pharmacist.
Hemp seeds, having trace amounts of non-psychoactive THC, can yield positive THC results.
Foods and Failed Drug Tests states that hemp seeds are rich in protein thus they are being manufactured into energy bars, hemp milk, and other tasty snacks. While some people claim that a failed drug test result is dependent on whether one has eaten hemp-based food or not, there is still no assurance that eating these products will mean false positive results. Often, when one consumes larger amounts of hemp-based food, there is a great chance that a positive THC drug test will occur. This is also true for hemp-based cosmetic products.
It is very unlikely for that to happen. With the sophisticated and more updated drug tests available around, it would be less likely to get positive results if one is exposed to secondhand pot smoke.
The only type of drug test that can determine approximately how long ago a drug was taken and for how long is a hair test (for up to 90 days). Drug testing using urine, saliva or even blood cannot determine these things. However, immunoassays performed in any of our SAMHSA drug testing locations always provide 100% reliable results.
Drug tests that use bodily fluids are designed to detect only if a specific drug or drug metabolite is present at the time the test is performed. Numerous factors unique to the individual being tested determine how long a drug stays in the person’s system. These variables include age, weight, body fat index, sex, metabolic rate, overall health and amount of drug consumed over what period of time.
An organization can conduct a drug testing following the mandatory guidelines for the Federal Workplace Drug Testing Programs published by the Substance Abuse and Mental Health Services Administration (SAMHSA). Aside from this law, private companies that intend to conduct drug testing must comply with their state laws and city code. Transportation companies may need to comply with the existing rules and regulations of the US Department of Transportation (DOT).
Some organizations may use the US Department of Health and Human Services (HHS) upon conducting a drug testing. In some instances, an employee may not know about the drug test results unless an MRO has done a final evaluation of the results.
The Medical Review Officer (MRO) is defined by SAMHSA as a licensed physician who has an appropriate medical training to interpret laboratory results including the employee’s medical history and any other relevant biomedical information.
Businessmen have viewed drug testing as an effective tool in increasing worker's performance. This means better job applicants, a better public image for the organization, fewer drug-related work problems and boosted employee morale.
An organization may conduct a drug test at any of the five following times.
There are several reasons behind why drug testing becomes effective in the workplace. According to The Effectiveness of Drug Testing, drug users tend to avoid applying for jobs in companies with existing drug testing policies. Likewise, a survey of Navy personnel showed that drug testing became the deterrent to drug use. However, all these perspectives on the effectiveness of the procedure will change depending on whether or not a certain company changes its perspective in implementing drug testing policies.
Companies who decide to enforce zero-tolerance drug programs can opt for any TestCountry Workplace Drug Testing Products.
A lot of people have found different methods to cheat drug tests to be able to enjoy years of continuous, undetected drug use. Some of these cheating methods have seemed to allow users to pass simple urine testing while many methods simply don’t work.
Tests conducted in any of our SAMHSA drug testing locations are virtually impossible to cheat, as laboratory technicians use state of the art equipment to rule out specimen adulteration.
Below are some of the widely advertised methods to cheat drug tests and the corresponding reasons why they don’t work:
Aspirin-and-Water Combination
There has been research circulating on the Internet that taking up to four Aspirin tablets a few hours before testing and drinking large amounts of water can help you cheat drug tests. Aspirin is said to reduce the sensitivity of Marijuana (THC) in the urine sample and, in combination with water, is said to bring the levels of THC down in drug test results to levels way below the cut-off levels. This method is both unreliable and dangerous since urine color is checked (colorless urine indicates cheating has been attempted) and excessive dosage of aspirin is dangerous.
Taking Vitamins
B-complex (B3 or Niacin, in particular) has been said to detoxify and cleanse the body from impurities and has been used to try to cheat drug tests but they’re all just false and empty promises. B3 or Niacin has no effect whatsoever on the number of illegal substances in your system. There have also been numerous cases of teenagers overdosing on Niacin, causing severe allergic reactions, palpitations and even liver damage.
Using Detoxifying ShampoosA hair follicle drug test is impossible to beat and this holds true despite advertisements for detoxifying shampoos on the Internet. Drug use is evident in hair follicles up to 30 days after use. Detox shampoos simply leave a residue on your hair that gives a better (but not fool-proof) chance of your drug test results coming back negative. Regular and heavy drug users, however, stand little chance of getting away with negative drug test results even if they use these so-called detox shampoos.
Claiming that Second-Hand Smoke Caused You to Fail
There are certain standards and cut-off levels that have been set by groups such as SAMHSA and NIDA for drug test results and this is to make sure that second-hand marijuana smokers won’t get tested positive for THC. If you are a primary smoker of Marijuana or Hashish, the levels of THC in your urine will definitely fall above the drug testing cut-off levels.
Drinking Lots of Cranberry or Orange Juice
A lot of people overload on cranberry juice or orange juice, thinking that this will dilute the number of drugs in their system, and subsequently allow them to pass urine testing. Drug adulteration kits test for the pH levels of urine samples and any acidic fruit juice can raise your urine’s pH level. Urine samples that have high pH levels are discarded and you may be asked to submit new samples until your urine has been determined as acceptable to be tested.
The following are the factors that may affect in detecting any illegal substance in the body:
Metabolism
Different people have different metabolic rates depending on their body type and the amount of physical activity they do every day. Metabolism is generally the amount of energy or calories you burn to maintain itself, so even while you sleep, eat, stand or do strenuous activities, your body burns calories to function properly. Some people have faster metabolic rates than others and a faster metabolism can decrease the detection time of drugs in your system.
Tolerance
Like metabolism, tolerance for illegal drugs is different for every individual. Tolerance for drugs can be built by repeated use (much like the way tolerance for alcohol is raised by drinking regularly). When tolerance for a drug is raised, the drug metabolizes faster in your body, thus decreasing drug detection times.
Frequency of drug intake
Although you might think that those who use drugs more frequently have an increased drug detection time, chronic or frequent users who have a high tolerance for drugs have lower detection times for they can eliminate drugs since it metabolizes in their systems faster.
Amount of body fat
Generally, your metabolic rate is indirectly proportional to your amount of body fat. Thus, the more body fat you have, the slower your metabolic rate, making it more difficult to pass drug tests if you are a drug abuser. Some drugs such as THC and PCP are also stored in fat cells, making it more difficult to eliminate if you have a large amount of body fat.
Urine pH
The acidity of your urine can either increase or decrease the detection time of drugs. The general rule is, the more acidic your urine, the lower the detection time, and vice-versa.
Age
As you grow older, your body’s metabolism slows down, thus increasing the time a drug stays in your system.
Drug consumption methods
The manner in which you take drugs affects drug detection time. Detection times increase, for instance, when a drug is ingested rather than smoked.
SAMSHA requirements will only improve drug testing quality. According to Drug Testing Myths Busted, SAMHSA limits its scope for drug testing in terms of the substance being tested. Among some of these drugs found within its limits are opiates, cocaine, amphetamines, THC, and PCP. Testing is also limited to Mandatory Federal Workplace Drug Testing.
There are some other certifications like those coming from the College of American Pathologists-Forensic Drug Testing that is considered to be more flexible than that of SAMHSA's certification.
Even if there is strong opposition to drug use while an employee is on the job, there is a legal action the employee can take when drug testing is involved. Also, employee drug testing involves a lot of other legal considerations. If an employer tests one employee, he must test all other employees within the organization.
Likewise, when an employer received federal funds for drug testing, then the policy and the test must be implemented in the workplace. It is also imperative to follow federal state laws on drug testing before conducting one.
The following are the most reputable online sources of information about drug testing:
National Institute on Drug Abuse (NIDA) – is a Federal scientific research institute under the U.S. Department of Health and Human Services. NIDA funds many global research efforts on drug abuse and addiction, including monitoring of emerging trends in drug use; the effects of drugs on the brain and body; developing and testing new drug abuse prevention and treatment methods, and publishing their findings to the public. This site also contains general information about the most common drugs of abuse, the physical signs of drug use or addiction, effective drug treatment programs and screening/assessment/drug testing resources.
Drug and Alcohol Testing Industry Association (DATIA) – this organization began in 1995 as the National Association of Collection Sites and has since expanded its scope to include the elevation and promotion of the standards of professionalism and quality control in the drug and alcohol testing industry. They develop and oversee education, accreditation and certification programs for the industry, serving also as coordinator regarding matters of industry regulations and the legislation needed to set things in motion; sample collection issues; and drug-free workplace rules and regulations. This organization represents over 1500 members that include not just collection sites but also laboratories, MROs, consortiums/TPAs and test equipment manufacturers.
Substance Abuse Program Administrators Association (SAPAA) – SAPAA is a primary resource for information and education. They provide a wealth of information on DOT developments, certification exams, strategic planning, drug and alcohol testing and legal and ethical issues.
Substance Abuse and Mental Health Services Administration (SAMHSA) – is the agency mandated by the U.S. Department of Health and Human Services to lead public health efforts towards the advancement of behavioral health within the U.S with the primary objective of reducing the impact of substance abuse and mental illness on America’s communities. The SAMHSA is responsible for setting the initial and confirmatory cut-off concentrations for Analytes during drug testing.
Partnership for Drug-free Kids – Originally founded in 1987 as a partnership for a Drug-free America, this non-profit organization works to reduce teen substance abuse and support families affected by alcohol or drug addiction. They are composed of parent coaches and scientific advisors seeking to change attitudes about drug and alcohol use, to educate individuals about the health risks and to effect a change in behaviors.
American Association of Medical Review Officers (AAMRO) – A medical society founded in 1991 dedicated to establishing standards and certifications on a national level for medical practitioners and other professionals in the field of drug and alcohol testing.
WebMD – and other reliable Health websites provide valuable health information and tools, including those needed to address problems related to drugs and drug testing in general. These resources are backed by a credible and timely response from clinical practitioners who provide their expertise in a consultative capacity.
United States Department of Labor – drug and alcohol abuse can lead to serious health and safety hazards that can negatively impact productivity and employee morale in the workplace. It can also potentially generate additional costs in the form of health care and short-term disability claims. All questions about pre-employment drug screening and workplace drug testing will very likely be answered here.
United States Department of Transportation – this site contains information on the rules related to the alcohol and drug testing of employees holding safety-sensitive positions in trucking, aviation, mass transit, railroads, pipelines and the transportation industry in general.
Department of Justice (DOJ) – Drug testing on a large scale was first implemented by the U.S. Department of Defense (DOD) back in the late 1960s to deal with marijuana and heroin use by U.S. military personnel in Vietnam. This ultimately led to the initial developments in urine drug test technology. Drug testing, however, is used differently in the military and in the workplace when compared to how it is used within the context of the criminal justice system, be it: for prosecution, for compliance with a probation order or pre-trial release, or for monitoring participants in drug court programs and treatment.
