Workplace drug testing can help employers maintain a safe work environment. But if a job candidate or employee fails a drug test, you should ensure compliance with your company drug testing policy and applicable laws. Learn what you should know about failed drug tests and potential next steps to maintain a fair and compliant drug testing program.
A drug test determines whether a person has certain illicit drugs or controlled substances in their system. There are several types of drug screenings an employer may conduct, including:
In 2022, the chances of failing a drug test were 4.6% among the US combined workforce, according to Quest Diagnostics. The combined workforce includes workers in the private sector and employees subject to federal drug testing mandates, such as pilots, truck drivers, nuclear power industries, and more. Positive drug tests reached their highest rate since 2001 — up 30% from an all-time low between 2010-2012.
Quest’s review of the data showed increases in positive tests for employees who work in national security and public safety. Marijuana, amphetamine, and cocaine use increased among federal employees in safety-sensitive roles, and marijuana use in the general workforce was up 9.1% year over year.
With failed drug test rates increasing, it’s important to understand the context surrounding a positive result and next steps. It’s also possible for prescription and over-the-counter medications to return false positives.
In general, if a job offer is contingent upon a candidate passing a drug test, employers may rescind the offer if the candidate fails a drug test. However, you must follow the proper steps to comply with both federal and state pre-employment drug testing laws.
Before taking any action, you should review your company’s drug testing policy and follow those guidelines. Next, you must adhere to all applicable laws. Federally, the Civil Rights Act of 1964 prohibits employers from selecting individuals for drug testing based on protected classes, such as race, religion, or national origin. The Americans With Disabilities Act of 1990 prohibits discrimination against job candidates based on previous drug use or enrollment in a rehabilitation program. It also makes it illegal to single out people for drug testing because they appear to be under the influence. Behavior that seems to be substance-induced may be related to a disability, illness, or medical condition.
Because the consequences of failing a drug test vary by state, it’s also important to follow state guidelines in response to a candidate’s failed pre-employment drug screen. For example, in Alaska, employers can use a failed drug test as grounds for not hiring a candidate. However, that candidate has the right to explain a positive drug test to the employer in a confidential setting. Employers in Alaska can also refuse to hire a candidate if they don’t submit to a drug test. If you decide not to proceed with an employment offer for a candidate or transfer or promotion of an employee due to a failed drug test, you must follow the adverse action process, as required by the federal Fair Credit Reporting Act (FCRA).
Where allowed by law, some employers may choose to conduct random or periodic drug testing of employees throughout their duration of employment. Others may test employees after an accident, upon returning to work after a violation, or when an employee shows signs of substance abuse. The consequences of failing a drug test at work vary based on company policy and applicable federal and state guidelines.
For example, some government-regulated workplaces must adhere to the Drug-Free Workplace Act of 1988 if they receive federal grants or contracts of $100,000 or more. Other employers with a zero-tolerance drug policy may terminate employees for failing a drug test if the state allows it.
In other states, like Vermont, companies can’t terminate employees after their first positive drug test if they agree to seek treatment. In Iowa, employees have the right to explain a failed drug test at work before an employer takes action.
If you decide to terminate an employee because of a positive drug test provided by a consumer reporting agency, like Goodhire, the FCRA requires that you follow the adverse action process which includes notifying the employee that the failed drug test for their job resulted in their dismissal and in certain instances provide the employee with an opportunity to respond.
On the other hand, employees who believe a drug test produced a false positive should speak with the hiring manager and contact the lab where the test was taken to discuss prescribed medications and supplements they’ve recently used with the Medical Review Officer. If they’ve been using a substance known to produce a false positive, the MRO may order an additional test called a “confirmatory test” before providing a conclusive result.
What happens if you fail a drug test after the confirmatory test? The Family and Medical Leave Act of 1993 allows employees of public sector organizations and certain private sector organizations to take up to 12 weeks of unpaid leave to seek treatment for substance use disorders. The law applies to employees who have worked for the employer for at least a year with 1,250 hours during the last 12 months.
A drug test may come back positive for many reasons — some obvious and some not-so-obvious. Here are several situations that may result in a failed drug test.
It depends on the employer. In general, the results of a failed pre-employment drug screen or failed drug screen for a current employee are confidential between the company that requested the test and the individual who took it.
However, the results of drug tests for employees who work for the Department of Transportation are kept on file in the Drug and Alcohol Clearinghouse generally for five years. Candidates must consent to allow an employer to view their records in the Drug and Alcohol Clearinghouse. However, candidates who don’t provide consent cannot hold safety-sensitive jobs.
Understanding the rules around failed drug tests can help you make compliant employment decisions. Here are some answers to commonly asked questions about failed drug tests.
In general, if a job is contingent upon passing a drug test, a failed drug test can disqualify a candidate from the position. However, employers must follow the proper procedures when rescinding an employment offer or terminating an employee to remain compliant with federal and state regulations.
In general, no. Convictions for drug-related charges may show up on a criminal background check, but the results of employment drug screenings generally will not appear on a criminal background check.
A failed drug test may be noted in the records of the employer that requested it, but they typically keep this information confidential. However, the results of a positive drug test for certain positions, such as those regulated by the Department of Transportation, may be available for future employers to see. DOT drug test results remain in the Drug and Alcohol Clearinghouse generally for five years.
If an employee fails a drug test, you should follow applicable company, state, and federal guidelines. Depending on the state, job candidates and employees may have the right to explain a positive drug test before an employer can take action. Job candidates and employees should be prepared to provide a list of all prescription and non-prescription medications they’re taking if they believe the test resulted in a false positive.
When you receive the results of a drug test, you will only see a positive or negative indication. A positive result does not provide context around how the drug got into the person’s system, how much the person took, when they took it, or whether they have an addiction. Rest assured, a Medical Review Officer (MRO) confirms the results of every drug test ordered by GoodHire, so you can be confident your drug test results are accurate.
If employers decide not to hire a candidate or to terminate an employee on the basis of a positive drug screening result provided by a consumer reporting agency like GoodHire, employers must provide the candidate or employee with a pre- and final adverse action notice as outlined by the FCRA.
When facing challenging hiring decisions, you may consider other steps such as reviewing Equal Employment Opportunity Commission (EEOC) guidance. Because the information that may be used in hiring decisions can vary between states, employers should consult with their legal team to help ensure you are following best practices as you screen and hire new employees.
Working with a CRA to conduct your organization’s drug testing can help you maintain a safe work environment and reduce the risk of accidents and injuries, while supporting compliance with applicable federal and state regulations.
GoodHire offers multiple drug screening options, including 4- to 10-panel, tests to meet the testing needs of your company. A Medical Review Officer (MRO) verifies all results to ensure the highest possible accuracy. We also offer other screening options to help you create a comprehensive background check program.
