When you are preparing for a job interview, you are probably making sure that your interview outfit is clean and ironed, you have work samples ready, your licenses or certificates are in order, and you have your resume handy.  You get yourself psyched up to answer questions and present yourself in the best possible light. You hope you’re ready for anything that they throw at you. Will you be ready if you are sent into the next room to provide a urine, hair, finger/toenail or oral fluid sample for a drug test? If you are looking for a job, it’s more and more likely that you will be asked to provide a sample. Clearly, now is the time to “Say No to Drugs!”

You may be thinking: “It doesn’t matter what I do on my own time. If they do a drug test I’ll have time to get clean if I get an interview.”  While this may have been the case in the past, it is no longer a safe excuse to keep using and hope that a few days is enough to clean up your act. While the urine drug screen is still the most common type of sample used for pre-employment and random drug testing, there are alternative specimens that can be used to detect drug use for months prior to the test.  It’s important to be aware of these drug and alcohol testing technologies so that you aren’t caught off-guard and denied the perfect job based on a positive drug test.

Drug testing technology has advanced dramatically since the tests were first instituted in some industries in the late 1980’s.  Standard urine tests can detect drug use on average within a one to three day window; and an oral fluid swab detects drug use within an even shorter period, only 2 to 24 hours.  Hair follicle, and finger or toenail drug tests are able to detect drug use for 3 to 6 months, depending on the drug andavailabilityof a sufficient amount of the specimen to be collected.  If you don’t know the test is coming, there is no way to prevent a positive test if you are a consistent, recreational drug user.

Hair and finger/toenail samples are very difficult to adulterate and very easy for the test collector to observe. The window of detection varies based on multiple factors, including frequency of use, concentration of the drug ingested, type of drug or drugs used, and even a person’s metabolism. What this all boils down to is that if you are job-hunting, you need to be prepared to take a drug test. Many prescription medications such as sedatives, opiates, and mood stabilizers can cause a positive test result.  In these instances, be prepared to provide a copy of your prescription to the Medical Review Officer (MRO).   If you don’t have a verifiable prescription for medication, just don’t take it.  In some states, although marijuana may have become legal for medical use, this does not guarantee that the company will hire you. Even if you have a valid prescription, marijuana use may go against their hiring or drug-free workplace policy.

Employers are increasingly testing prospective employees to comply with drug-free workplace mandates.  Some industries, for example, those that hire drivers, pilots or heavy machinery operators, are required to conduct drug testing on candidates and random testing on employees due to government regulations.  Other employers just want to prevent problems on the job that can lead to injury or liability.  And, employers have the right to conduct drug testing regardless of the type of work or environment. As long as they test everyone, drug testing is not considered a discriminatory hiring practice.

If you’re gearing up for a job search, get clean now and be sure that you put your best foot (and hair, fingernail and toenail!) forward.
