WHAT ARE THE REASONS FOR DRUG TESTING?

Who can be tested for drugs?

If you’re reading this, you’re probably already under imminent threat of a drug test. If not, you’re worried about a loved one or just curious. We try to shed some light on this topic that is of increasing concern with the legalization of recreational cannabis. Just because it’s legal doesn’t mean everyone can use it. Drug testing is therefore about checking whether people are using or have used drugs. These tests can be done routinely or randomly in the following cases:

  • People who are applying for or already working in certain types of jobs (such as pilots or truck drivers)
  • People in a substance abuse treatment program, to detect ongoing substance abuse and thus the best treatment plan
  • People who are required to be tested as part of custody hearings
  • For life insurance applications with medical examination
  • Certain groups such as students, athletes and prisoners
  • People who have been involved in motor vehicle or boating accidents, or work-related accidents
  • Persons who attempted suicide by uncertain means
  • Persons subject to a court-ordered substance abuse treatment program or with conditions of probation or parole requiring abstinence, to monitor compliance
  • The military

Drug testing demystified

Drug testing cannot determine how often a substance is used, and therefore also cannot distinguish between occasional and regular users. In addition, drug testing only targets certain substances and therefore leaves others out. These screenings most often target the following substances:

  • Marijuana, (cannabis, pot)
  • Cocaine
  • Alcohol
  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Natural and semi-synthetic opiates
  • Phencyclidine (PCP)

A sample of urine, blood, exhaled air, saliva, sweat, or hair may be analyzed. Urine tests are the most common because they are noninvasive, quick, and can detect many drugs.

They can detect drugs that have been used in the previous one to four days, sometimes for longer, depending on the drug used. Blood tests are rarely performed because they are invasive and only detect drugs up to a few hours after ingestion.

Hair analysis is not widely available, but can detect drugs if they have been used less than 100 days. There are extremely effective shampoos to give your hair a deep clean if you don’t want to shave it.

Health professionals can directly observe the sample collection and seal it to ensure that it is not tampered with.

The limitations of drug testing

Drug tests are not always accurate. The most commonly performed urine tests give partial and sometimes incorrect results. Sometimes the tests do not detect a drug the person is using (a false negative result). This can happen, for example, when a test is not designed to detect a specific drug or has limited sensitivity to that drug, when the urine is very dilute and the amount of drug in the urine is below the detection limit of the test, or when the person mixes a substance with the urine to alter the sample or presents a sample produced by someone else.

Inversely, tests sometimes appear positive when the person is not using drugs (false positive result). For example, consumption of poppy seeds can cause a false positive result for opiates (heroin is derived from poppies).

The real question is: do you want to take the chance to test positive? Surely not, so our advice and cures can help you put all the odds on your side. No one can guarantee your success considering all the factors, but we guarantee that you will have all the tips to make an optimal detoxification cure.

TYPES OF DRUG TESTS

Drug testing can be done in a variety of ways. The two most popular tests are point-of-care testing devices and laboratory tests. An instant drug test, can be used to screen for the presence of drugs in urine or oral fluid and provide qualitative results. A laboratory can also be used to perform qualitative screening of the sample as well as quantitative confirmation of the drug test results using specialized laboratory equipment.

Here are the major drug tests and what you need to know.

On-site urine drug testing

Urine testing is the most commonly used method for detecting illicit drugs. Piss-in-a-cup sampling is noninvasive; it does not involve the use of needles. Urine samples can contain high concentrations of parent drugs (drugs of abuse) and drug byproducts. However, urine samples are less effective than some other methods for detecting drugs and alcohol because they have a short lookback period. In other words, a urine test is less likely to detect regular drug use beyond a 48-day period. Another disadvantage of urine tests is the ease and possibility of tampering with samples.

Lab or on-site blood testing

Although blood tests are more invasive than breathalyzer and urine tests, they are the most effective at detecting specific levels of alcohol concentration. Some blood tests show the precise levels of intoxication 24 hours after drinking.

Because of the invasive nature of traditional blood sampling, which involves a needle stick in the arm, many laboratories and other facilities now offer less invasive methods of sampling, such as sampling with a drop of blood.

These blood tests can reveal drug metabolites in the blood, as well as the actual amount or level of drug in the blood. This collection technique reduces the risk of sample tampering or substitution by patients, as is the case with urinalysis.

Oral drug testing and saliva drug testing

Saliva testing is another minimally invasive method of drug testing. However, saliva is only useful for testing recent drug use. For example, saliva testing for marijuana can only yield accurate results if the subject has smoked/used cannabis within 4-10 hours.

An oral drug test is therefore an easy way to detect the presence of drugs without having to worry about the confidentiality of urine drug tests.  

Hair drug testing

Hair drug tests are normally performed by a certified laboratory. A hair test can screen for a number of commonly used drugs and prescription medications. The hair test can detect the use of these drugs up to 100 days back.

The drug metabolites enter the blood vessels of the scalp. The hair filters the drug and keeps a permanent record of the drug use. This means that a user who used cocaine, marijuana or other drugs several months ago will test positive because the drug residue remains in the hair.

In summary

Keep in mind that this cat-and-mouse game is fueled by many increasingly sophisticated techniques to catch the wrongdoers.

Your best bet is to detox as soon as possible so that no traces of drugs or alcohol are found in your samples, whatever they may be.
