Workplace Drug Testing Laws in Virginia: What Employers Can Do
Last reviewed: July 2026
Quick Answer
Yes, Virginia employers can drug test employees under Virginia Code section 40.1-28.7, but only with advance written notice and following strict procedural requirements. Testing must be based on reasonable suspicion, post-accident circumstances, or enrollment in a safety-sensitive position program. Employers must use certified laboratories, provide confirmation testing opportunities, and follow chain-of-custody procedures. Positive results alone cannot justify termination without proper process and consideration of alternative explanations.
Key Facts
- •Virginia allows employers to conduct drug tests but must follow specific legal procedures and provide notice.
- •Employers cannot test without reasonable suspicion, post-accident, or as part of required safety programs.
- •Employees have rights to see test results and request confirmation testing at their own expense.
- •Positive results must be confirmed by a second test before disciplinary action can be taken.
Federal Law: The Baseline
Federal law does not comprehensively regulate private sector drug testing. The Americans with Disabilities Act (42 U.S.C. section 12114) prohibits discrimination based on drug testing results and protects employees with addiction disabilities. The Department of Transportation regulates drug testing for employees in safety-sensitive positions in transportation industries. The Nuclear Regulatory Commission requires drug testing for certain nuclear facility workers. The federal government prohibits pre-employment drug testing discrimination under the ADA but does not mandate drug-free workplace testing procedures. Enforcement falls to the EEOC for discrimination claims and the DOL for specific industries. Most private employers are free to establish their own drug testing policies within constitutional bounds and applicable state laws.
Virginia Law: What's Different
Virginia Code section 40.1-28.7 provides the framework for employer drug testing and is stronger than the federal baseline in several respects. Virginia requires employers to provide written notice of drug testing policies before implementation, which exceeds federal requirements. The state law mandates that testing can only occur in specific circumstances: with reasonable suspicion based on objective facts, following workplace accidents, or as part of a comprehensive safety program for safety-sensitive positions. Employers must use certified laboratories and follow strict chain-of-custody procedures.
Unlike federal law which allows broad discretion, Virginia requires confirmation testing when initial results are positive. Section 40.1-28.7 explicitly permits employees to request and pay for independent confirmation testing at their own expense. The law applies to all Virginia employers with no minimum employee threshold, covering both public and private sector employers. Notably, Virginia does not authorize random drug testing without reasonable suspicion or post-accident circumstances, creating stronger employee protections than many other states.
Virginia Code section 40.1-28.7:1 requires employers to inform employees in writing about the specific circumstances under which testing will occur, procedures for handling positive results, and employee rights regarding test results and confirmation testing. Employers must maintain confidentiality of test results and can only disclose information to employees, legal representatives, insurance carriers, and designated medical review officers. The state provides a private right of action under tort law for violations of testing procedures, allowing employees to sue for damages including attorney's fees.
Key Numbers & Thresholds
Written notice must be provided before any drug testing program is implemented. Confirmation testing must be requested within 10 days of notification of positive results. Chain-of-custody procedures must be documented in writing. Employers cannot use test results older than 30 days without justification. No minimum employer size threshold applies; all Virginia employers are covered by the statute.
Exceptions & Special Cases
Virginia law provides limited exceptions to testing restrictions. Safety-sensitive positions explicitly referenced in federal regulations (Department of Transportation positions, nuclear industry workers, certain aviation roles) may be subject to broader testing without requiring reasonable suspicion, as federal law preempts state law in these regulated industries. Employers in construction and manufacturing with documented history of workplace safety incidents may test after accidents without independent justification.
The law does not apply to drug testing required by federal law, federal contractors, or positions requiring security clearances. Testing of job applicants before hiring has more flexible requirements than testing of current employees, though employers must still follow procedural safeguards. An employee's admitted prior drug use or presence during workplace incident investigation may constitute reasonable suspicion. However, mere proximity to drug use or generalized workplace rumors do not constitute reasonable suspicion.
Employees cannot be tested based solely on physical appearance, age, or demographics. Virginia permits testing of employees involved in accidents only if the accident resulted in injury or significant property damage. Importantly, a single positive test result without confirmation is not sufficient grounds for termination; Virginia requires the second confirmatory test before disciplinary action. The law does not require employers to test at all—it only regulates testing when employers choose to conduct it.
What to Do If Your Rights Are Violated
Step 1: Document everything related to the drug testing. Keep copies of the employer's written drug testing policy, any notification letters received, the date and circumstances of when testing was requested, and any written communication about test results. If you suspect reasonable suspicion is lacking, document the specific statements made by supervisors and the actual circumstances of the workplace incident or concern. Maintain records of any side effects or complications experienced during the testing process.
Step 2: Request your test results in writing from your employer immediately after learning of a positive result. Under Virginia Code section 40.1-28.7, you have the right to see your results and know what substance triggered the positive. If you believe the result is inaccurate, request confirmation testing at a different certified laboratory within 10 days. Request this confirmation in writing and keep copies. Ask your employer about their procedures for handling positive results and whether disciplinary action has been determined.
Step 3: File a complaint with the Virginia Department of Labor and Industry if you believe the employer violated testing procedures. The agency can be reached at 804-786-2377 or through their website at www.doli.virginia.gov. You may also file a civil lawsuit under Virginia Code section 40.1-28.7 for damages if testing violated the statute's requirements. There is no strict filing deadline, but acting quickly preserves evidence. Provide documentation of the testing circumstances, written policies, and any evidence the employer failed to follow required procedures.
Step 4: The Virginia Department of Labor and Industry investigation process typically involves reviewing the employer's drug testing procedures, examining chain-of-custody documentation, and verifying that proper notice was provided. Investigations generally take 60-90 days. The agency will contact you if additional information is needed. You may also consult the laboratory that performed the test about whether proper procedures were followed. If the initial test was positive and no confirmation was offered, this is a clear violation.
Step 5: Consult an employment attorney experienced in Virginia drug testing law before accepting any adverse employment action based on a positive test result. An employment lawyer can review whether your employer complied with Virginia Code section 40.1-28.7 requirements and advise on whether you have grounds for a civil claim for damages, lost wages, and attorney's fees. Contact the Virginia State Bar's lawyer referral service at 800-552-7977 if you need assistance finding an attorney.

Frequently Asked Questions
Can my Virginia employer test me for drugs without telling me first?
No. Virginia Code section 40.1-28.7 requires employers to provide written notice of drug testing policies before implementation. You must receive clear written information about when testing may occur, the procedures used, and your rights regarding test results and confirmation testing. If an employer attempts to test you without providing prior written notice of the policy, this violates state law. However, the notice requirement does not prevent testing in emergency situations related to workplace safety incidents—the employer must still follow up with documentation. The written policy notice must be given before the drug testing program begins, not just before individual tests. If your employer suddenly announces a drug testing program and immediately tests you without prior written notification, you may have grounds for a legal claim.
What counts as reasonable suspicion for drug testing under Virginia law?
Reasonable suspicion under Virginia Code section 40.1-28.7 must be based on objective facts and observable behaviors, not hunches, stereotypes, or proximity to drug use. Examples include: erratic behavior, slurred speech, inability to perform job duties, involvement in a workplace accident causing injury or property damage, or discovery of drug paraphernalia at the workstation. One coworker's rumor or an employee's off-duty conduct generally does not constitute reasonable suspicion. Supervisory concern about an employee's changed behavior can support testing only if specific, documented observations are present. If a supervisor appears unable to articulate specific facts supporting reasonable suspicion beyond general workplace tension or personality conflicts, the testing may violate Virginia law. Importantly, reasonable suspicion cannot be based on an employee's race, age, appearance, or prior personal struggles with addiction. The employer must document the specific observations that led to the testing request.
Can I request a second drug test if my employer's test comes back positive?
Yes, absolutely. Virginia Code section 40.1-28.7 explicitly grants you the right to request a confirmation test at a different certified laboratory at your own expense. You have 10 days from notification of the positive result to request this confirmation. The confirmation test must use a different sample collection and analysis method when possible. You should request confirmation testing in writing to create a clear record. If the original test used a urine sample, a hair or blood test may be used for confirmation. The cost of confirmation testing is your responsibility, which typically ranges from $100 to $300 depending on the test type. If the confirmation test is negative, it contradicts the original result and should be presented to your employer as evidence that the initial positive was a false positive. Many employers have policies about who bears the cost of confirmation testing if the second test is negative.
Can my Virginia employer fire me based on a single positive drug test?
No, not immediately and not without following proper procedures. Virginia Code section 40.1-28.7 requires confirmation testing before disciplinary action can be taken based on a positive result. A single positive test is not sufficient grounds for termination under Virginia law. The employer must offer or provide confirmation testing and allow you reasonable opportunity to request independent confirmation. Only after a confirmed positive result can the employer lawfully take disciplinary action. Even then, Virginia recognizes that a positive test result alone does not necessarily prove impairment or misconduct—some substances remain detectable for weeks after use, including marijuana. Your employer must consider the substance involved, the timing of use relative to work hours, and whether impairment actually occurred. If you have a medical explanation for a positive result (such as prescribed medication), this must be considered before termination. Termination for a single unconfirmed positive test would violate Virginia's testing statute.
Does Virginia law protect employees who take prescribed medications that show up on drug tests?
Yes, Virginia Code section 40.1-28.7 requires employers to consider legitimate medical explanations for positive test results. If you take a prescription medication that triggers a positive result for controlled substances—such as opioid painkillers, benzodiazepines for anxiety, or ADHD medications containing amphetamines—you should provide documentation of the prescription to your employer. The employer must consider this medical information before taking disciplinary action. Many employers use Medical Review Officers (MROs) who specifically evaluate positive results for legitimate medical explanations. You should proactively disclose relevant prescriptions to the testing facility or your employer before testing occurs if you know certain medications may cause positive results. However, note that marijuana remains illegal under Virginia law for recreational use, so a positive marijuana test is not protected by medical explanation unless you have a valid Virginia medical cannabis certification. For other controlled substances with legitimate prescriptions, employers cannot discriminate based on the positive result without evidence of impairment or violation of workplace conduct policies.
