When to perform drug testing

If you are regulated by the Department of Transportation, you are required to adhere to strict regulations on employee drug testing. Many employers of the general workforce use those regulations when creating their own drug free workplace program.

USAMDT offers Oakdale businesses a program that tailors your drug testing policies for 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, such as:

Pre-employment drug testing

The DOT requires an employee to have a negative drug test result on file before a driver is permitted to get behind the wheel. Many employers for the general workforce require pre-employment drug testing before a new hire begins work as well.

Random drug testing

Most people associate random drug testing with DOT compliance, however, it’s common in other industries too. The department requires all safety-sensitive employees to have their names added to a random pool. The pool is used to randomly generate a list of employees who are instructed to report for a drug test immediately.

DOT drug testing

The DOT requires that all members of a safety-sensitive workforce are drug tested before they use a commercial motor vehicle (CMV). Additionally, drivers are entered into the random test pool and may be called up for drug testing periodically 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 personnel must be trained to identify substance abuse. If they believe someone is impaired, they should know the company policy and document everything 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 at fault and protect 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 have tested positive for drugs. 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 perform drug tests throughout Oakdale utilizing several different methods, depending on your circumstances. Each method has pros and cons, and you should talk to one of our specialists if you need advice on deciding which is best for your needs.

All test samples undergo 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.

The industry standard is still the urinalysis. (This is currently the only testing method the DOT will accept.) Urinalysis is fast, easy, and cost-effective, but it does come with a few drawbacks.

You need to secure a private bathroom, and you have to disable both the sink and toilet, and pour a bluing agent in the water in the toilet bowl. Privacy concerns may also be an issue because a test must be conducted by an administrator of the same sex.

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 drug use from about a half-hour after use up to a few weeks after discontinuing use. Chronic marijuana use is an exception to the rule. Addicts 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 somewhat newer, but is still just as accurate as urine drug testing. Additionally, it’s just as fast, easy, and inexpensive. It provides the smallest detection window though. Still, it identifies most drugs within just a few minutes of use. It only identifies drugs for a period of up to 72 hours prior to the test.

The largest advantage of the mouth swab drug test is that it can be administered literally anywhere—even in plain view of staff. The test only requires putting a mouth swab between the lower cheek and gum. The employee holds it in place until it becomes saturated. The 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 identifies recent drug use, it’s becoming a popular option for random drug testing. In fact, the HHS (The Health and Human Services Administration) approved the use of this testing method as an alternative 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.


The less common hair follicle drug test offers the same simplicity 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 business owners. In fact, the DOT officially requested that the hair test replace the urine drug test. The request is working through the chain-of-command and many expect to hear the final word anytime now.

This test requires the administrator to cut 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 a problem with having their hair cut.

No worries.

Body hair can be collected instead and is tested by volume rather than length. Administrators gather enough hair to equal the size of a cotton ball about an inch in diameter.

Body hair offers a longer detection window compared to head hair. Hair collected from an employee’s head can detect drug use for up to 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.
