After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. Be sure to tell the testing provider or your health care provider if you are taking any prescription drugs, over-the-counter medicines, or supplements because they may give you a positive result for certain illegal drugs.
Also, you should avoid foods with poppy seeds, which can cause a positive result for opioids. There are no known physical risks to having a drug test, but a positive result may affect other aspects of your life, including your job, your eligibility to play sports, and the outcome of a court case. If your results are negative, it means no drugs were found in your body, or the level of drugs was below an established level, which differs depending on the drug.
If your results are positive, it means one or more drugs were found in your body above an established level. However, false positives can happen. So if your first test shows that you have drugs in your system, you will have further testing to figure out whether or not you are actually taking a certain drug or drugs.
Before you take a drug test, you should be told what you are being tested for, why you are being tested, and how the results will be used.

The drugs most often tested for include: Marijuana Opioids , such as heroin , codeine, oxycodone, morphine, hydrocodone, and fentanyl Amphetamines, including methamphetamine Cocaine Steroids Barbiturates, such as phenobarbital and secobarbital Phencyclidine PCP Other names: It may be used for: Professional and collegiate athletes usually need to take a test for performance-enhancing drugs or other substances.
Legal or forensic purposes. Testing may be part of a criminal or motor vehicle accident investigation. Many drugs stay in the system from 2 to 4 days, although chronic use of marijuana can stay in the system for 3 to 4 weeks or even longer after the last use.
Drugs with a long half-life, such as diazepam , may also stay in the system for a prolonged period of time. Drugs can be detected in hair samples up to six months, although urine drug screen tests are used for most workplace drug screens. Examples of drugs that can be detected in hair-testing include alcohol, marijuana, cocaine, and amphetamines.
This table should be used as a general guideline only. Many variables may affect the amount of time that a drug remains detectable in the urine or other biological samples, as noted by LabCorp and in the Drugs of Abuse Reference Guide. Some employees may ask does alcohol show up on a drug test? Alcohol has a short half-life in the urine. A urine drug test for alcohol may detect alcohol for 2 to 12 hours. Results from workplace drug testing are fairly quick and can usually be received in a few days.
An employer may also request to have the test done with a rapid test that can provide results on the same day. Negative results are usually received within 24 hours; however, a positive screen will require further testing that may take a few days up to one week. If the initial screen is negative, a medical review officer MRO will typically contact the employer with the results.
If a positive result occurs, a MRO will contact the applicant for further questioning. It is important to notify the laboratory or MRO of any medications currently in use, including prescription , over-the-counter or herbal medications. The applicant may have to provide proof of a valid prescription and prescriber information for prescription medications. A concern for anyone undergoing drug testing is the possibility of a false positive result. Initial screening drugs tests may infrequently result in false positive results, although confirmatory GC-MS testing greatly lessens the chances of a false positive - reducing the risk to close to zero.
It is important that a person undergoing drug testing complete an accurate history of all prescription, OTC, and herbal drug use prior to the time of the sample collection. Certain substances, over-the-counter OTC or prescription drugs may result in false positives due to cross-reactivity with other substances, although many assays have been reformulated to avoid these possibilities.
Poppy seeds and dextromethorphan have been reported to lead to a false positive result for opiates. Decongestants ephedrine have been implicated in causing false positives for amphetamines. The body metabolizes codeine to morphine and both substances may be found upon testing.
If benzoylecgonine, the main metabolite of cocaine is detected, the person cannot claim that the result is a false positive due to Novocaine or any other "-caine" type of drug. Benzoylecgonine is only found in nature as a metabolite of cocaine, and there would be no other valid reason for it to be present in a drug screen. As previously mentioned, confirmatory testing with GC-MS will identify individual drugs or metabolites in a sample, and almost eliminate the chance for a false positive result.
Other abnormalities in the urine screen may indicate that results may be a false negative or that there was deliberate adulteration of the sample. In some labs, patients who receive a positive result may have the option to pay for an independent retest of the urine sample that was originally submitted. A new urine sample is not allowed for the retest as the drug in question may have been excreted from the body by that time.
The results of drug testing should remain confidential and kept separate from the regular employee work file. Legal rules vary from state to state where marijuana is now legal for recreational use. Also, as marijuana stays in the system over a prolonged period of time, the employee may use marijuana legally, but be drug tested at a later time and lose their job.
In general, according to Law, marijuana legalization laws in states where it is legal support employers in drug testing for marijuana use and firing people for it. Marijuana use is still illegal under federal law, and many employers prefer to maintain their drug-free workplace policies.

In consultation with Dr. In doing so, he instituted mandatory drug-testing for all safety-sensitive executive-level and civil-service Federal employees. This was challenged in the courts by the National Treasury Employees Union. In , this challenge was considered by the US Supreme Court. Failing a drug test can be construed as possession of a controlled substance, resulting in mandatory revocation and imprisonment.
There have been inconsistent evaluation results as to whether continued pretrial drug testing has beneficial effects. Testing positive can lead to bail not being granted, or if bail has already been granted, to bail revocation or other sanctions. Arizona also adopted a law in authorizing mandatory drug testing of felony arrestees for the purpose of informing the pretrial release decision, and the District of Columbia has had a similar law since the s.
It has also been argued that such testing potentially implicates the Fifth Amendment privilege against self-incrimination , the right to due process including the prohibition against gathering evidence in a manner that shocks the conscience or constitutes outrageous government conduct , and the prohibition against unreasonable searches and seizures contained in the Fourth Amendment.
According to Henriksson, the anti-drug appeals of the Reagan administration "created an environment in which many employers felt compelled to implement drug testing programs because failure to do so might be perceived as condoning drug use. This fear was easily exploited by aggressive marketing and sales forces, who often overstated the value of testing and painted a bleak picture of the consequences of failing to use the drug testing product or service being offered.
According to an uncontrolled self-report study done by DATIA and Society for Human Resource Management in sample of 6, randomly selected human resource professionals , human resource professionals reported the following results after implementing a drug testing program: A person conducting a business or undertaking PCBU—the new term that includes employers has duties under the work health and safety WHS legislation to ensure a worker affected by alcohol or other drugs does not place themselves or other persons at risk of injury while at work.
Workplace policies and prevention programs can help change the norms and culture around substance abuse. All organisations—large and small—can benefit from an agreed policy on alcohol and drug misuse that applies to all workers. Such a policy should form part of an organisations overall health and safety management system. PCBUs are encouraged to establish a policy and procedure, in consultation with workers, to constructively manage alcohol and other drug related hazards in their workplace.
A comprehensive workplace alcohol and other drug policy should apply to everyone in the workplace and include prevention, education, counselling and rehabilitation arrangements. In addition, the roles and responsibilities of managers and supervisors should be clearly outlined. In Victoria, roadside saliva tests detect drugs that contain: In February a New South Wales magistrate "acquitted a man who tested positive for cannabis".
He had been arrested and charged after testing positive during a roadside drug test, despite not having smoked for nine days. He was relying on advice previously given to him by police. In the United States federal criminal system, refusing to take a drug test triggers an automatic revocation of probation or supervised release.
In Victoria, Australia the driver of the car has the option to refuse the drug test. The second refusal triggers an automatic suspension and disqualification for a period of 4 years and an even larger fine. From Wikipedia, the free encyclopedia.
