When should you conduct a drug test
If your business is regulated by the DOT, you must follow particular laws on employee drug testing. Many employers for the general workforce follow these regulations when developing their own drug free workplace program.
USAMDT offers Ivanhoe businesses a program that customizes your drug testing policies to meet your specific needs. We’ll even write and then implement your policy, and provide employee education and staff training at your request.
There are several reasons to conduct workplace drug testing, including:
Pre-employment drug testing
The Department of Transportation requires an employee to have a negative drug test result on file before a driver is permitted on the road. Many employers of non-DOT-regulated companies require a pre-employment drug test before a new hire can begin work as well.
Random drug testing
Most people associate random drug testing with Department of Transportation regulations, however, it’s common in other industries too. The department requires all members of a safety-sensitive workforce to have their names added to a random pool. The pool is used to randomly create a list of employees who are instructed to report for a drug test immediately.
DOT drug testing
The Department of Transportation requires that all safety-sensitive employees have been drug tested before they operate a commercial motor vehicle (CMV). In addition, drivers are entered into the random test pool and may be called up for drug testing at various intervals throughout the year. Post-accident, probationary, reasonable suspicion, and return to duty testing are also required.
The DOT requires a urine test and looks for the following drugs:
- Amphetamines and methamphetamines
- Cocaine
- Marijuana
- PCP
- Opiates including synthetic opiates
- Oxycodone
- Oxymorphone
- Hydrocodone
- Hydromorphone
Reasonable suspicion drug testing
Your management staff must be trained to identify drug impairment. If they suspect an employee is impaired, they should know the company policy and have everything documented before approaching the employee. The suspected employee must then report for drug-testing immediately.
Post-accident drug testing
If there is an accident at work, drug testing all staff involved can help identify who is responsible and defend you from legal liability.
Return to duty drug testing
A certified SAP (Substance Abuse Professional) works with the driver, or other safety-sensitive employees, who had a positive drug test result. The SAP signs them off as able to return to work after that safety-sensitive employee has a negative drug test result.
Drug testing methods
We can administer drug tests throughout Ivanhoe using a variety of different methods, depending on your needs. Each method has pros and cons, and you should speak to one of our specialists if you need advice on deciding which is best for you.
All test samples go through an initial screen. The immunoassay (IA) test identifies a positive or negative result. Most drug tests are negative and this cost-efficient test saves employers money because no further testing is needed.
Tests returning a positive result are sent on for confirmation testing. The gas chromatography/mass spectrometry (GC/MS) test confirms the positive result by identifying the drug and the level contained in the specimen.
Urinalysis
The industry standard is a urinalysis. (This is currently the only testing method approved for DOT drug testing.) Urinalysis is quick, easy, and cost-effective, but it does come with a few drawbacks.
You need to secure a private bathroom, and you need to disable the sink and toilet, and pour a bluing agent in the water in the toilet bowl. Privacy concerns may also present an issue because a test must be conducted by a collector of the same gender.
Additionally, the privacy factor also provides an opportunity to attempt to cheat the test by adding adulterants, which creates a negative dillute or positive dillute drug test result, or even substituting the specimen entirely. However, technological advances in both testing procedures and lab equipment make it increasingly difficult for drug users to succeed.
This testing method identifies drugs from about a half-hour of ingestion up to several weeks after the last use. Chronic marijuana use is an exception to the rule. Regular users can test positive for up to thirty days. You can learn more here: How Long Does Marijuana Stay in Your System?
Employers receive test results in a few days.
Mouth swab / oral fluid
This method of drug testing is relatively newer than other methods, but is still just as accurate as a urinalysis. Additionally, it’s just as fast, simple, and inexpensive. It offers the shortest window of detection though. Still, it drug-testing most drugs within minutes of use. It only detects drugs for a period of up to 72 hours prior to the test.
The biggest advantage of a mouth swab drug test is that it can be conducted literally anywhere—even in plain sight of other employees. The test only requires placing a mouth swab between the lower cheek and gum. The employee holds it in place until it is saturated. The entire process usually takes less than. Despite the claims we hear many drug users make, the only way to pass a mouth swab drug test is to not use drugs.
Results are received in just a few days.
Because it can detect recent drug use, it’s becoming a popular choice for random drug testing. In fact, the HHS (The Health and Human Services Administration) approved the use of this testing method as an alternate drug testing method for all federally mandated employers as of January 1, 2020.
At this time, it’s unclear whether or not the DOT will incorporate the test into its regulations.
Hair
The less common hair follicle drug test offers the same convenience as mouth swab testing, however, it’s more expensive.
The fact that it offers a 90-day detection window overrides the added cost in the eyes of more and more employers. In fact, the DOT officially requested that the hair test replace the urinalysis. The request is passing through the chain-of-command and many expect to hear the final word soon.
This test requires the administrator to cut a small (less than 1” wide) section of hair, ideally from near the base of the scalp, and secure it in a zipper-lock plastic bag. While this testing method is simple and convenient, some staff may have an issue with having their hair cut.
No worries.
Body hair can be used instead and is tested by volume instead of length. Administrators collect enough hair to equal the size of a cotton ball about an inch in diameter.
Body hair provides a longer detection window compared to head hair. Hair collected from an employee’s head can detect drug use for about 90-days, while hair collected from the body will detect drug use for about a year.
The hair test doesn’t detect current impairment or very recent drug use.
