When to perform a drug test
If your business is regulated by the DOT, you are required to follow particular laws in regard to employee drug testing. Many employers of non-DOT-regulated companies follow those regulations when creating their own drug free workplace program.
USAMDT offers Norcross employers a program that tailors your drug testing policies to meet your specific needs. We’ll even create and then implement your policy, and provide employee education and staff training at your request.
There are a number of reasons to perform workplace drug testing, including:
Pre-employment drug testing
The Department of Transportation requires that a negative drug test result is on file before a driver is permitted to get behind the wheel. Many employers for the general workforce require a pre-employment drug test before a new hire begins work as well.
Random drug testing
Most people associate random drug testing with Department of Transportation regulations, however, it’s also common in other industries too. The department requires all safety-sensitive employees to have their names added to a random pool. This pool is used to randomly produce a list of employees who are required to take a drug test.
DOT drug testing
The Department of Transportation requires that all members of a safety-sensitive workforce have been drug tested before they operate a commercial motor vehicle (CMV). In addition, drivers are placed 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 mandatory.
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
Train your management staff to recognize the signs of substance impairment. If they believe an employee is under the influence, they should know the company policy and document everything before approaching that employee. The suspected employee must then report for drug-testing immediately.
Post-accident drug testing
If there is an accident on-site, drug testing all employees involved can help determine who is to blame 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 the safety-sensitive employee has a negative drug test result.
Drug testing methods
We can perform drug tests throughout Norcross utilizing several different methods, depending on your circumstances. Each method has pros and cons, and you should speak to one of our specialists if you need help deciding which is best for your needs.
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 go on for further confirmation testing. The gas chromatography/mass spectrometry (GC/MS) test confirms the positive result by identifying the drug and the level contained in the sample.
Urinalysis
The industry standard is the urine drug test. (This is currently the only testing method the DOT will accept.) Urinalysis is quick, simple, and inexpensive, but it does come with a few drawbacks.
You need access to a private restroom, and you must disable the sink and toilet, and place a bluing agent in the water in the toilet bowl. Privacy concerns could also present an issue because a test must be conducted by a collector of the same gender.
In addition, the privacy factor also provides an opportunity to attempt to cheat the test by adulterating the specimen, which creates a negative dillute or positive dillute drug test result, or 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 can identify drug use from about a half-hour after use up to a few weeks after the last use. Chronic marijuana use is an exception to the rule. Addicts can test positive for over 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, but is still every bit accurate as a urinalysis. Additionally, it’s just as quick, easy, and inexpensive. It offers the shortest window of detection though. Still, it drug-testing most drugs within minutes of use. It only identifies drug use for a period of up to 72 hours prior to the test.
The largest advantage of mouth swab drug testing is that it can be performed literally anywhere—even in plain sight of staff. 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 couple of days.
Because it can identify 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 uncertain whether or not the DOT will approve this method 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 additional 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 working through the chain-of-command and many expect to hear the final word soon.
This test requires the administrator to clip a small (less than 1” wide) amount of hair, ideally from near the base of the scalp, and secure it in a zipper-lock plastic bag. While this testing method is easy and convenient, some employees may have an issue with having their hair cut.
No worries.
Body hair can be collected 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 than 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 up to a year.
The hair test can’t detect current impairment or very recent drug use.
