Drugs, Morality, and the Law, Garland Press, These requirements are compatible with general employment law while promoting the public's interest in fighting drug use.
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.
How long does alcohol stay in urine? 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.
How long does it take to get drug test results? 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 prescriptionover-the-counter or herbal medications. The applicant may have to provide proof of a valid prescription and prescriber information for prescription medications.
Can a workplace drug test be false positive or false negative? 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.
Do poppy seeds cause a false positive drug test? 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.
What can cause a false positive for cocaine? 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.
Doering, et al Does passive smoke inhalation cause a false positive for marijuana? Other abnormalities in the urine screen may indicate that results may be a false negative or that there was deliberate adulteration of the sample. To help avoid this problem, the testing lab may color the water in their toilet blue to prevent the sample being diluted with water from the toilet.
All of these variables, and others, are looked at in the lab analysis. 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.Drugs Testing Book - All about drugs testing.
