Texas Updated Drug Testing Laws in 2024: A Comprehensive Guide

It can be difficult to keep up with the constantly changing legislation regarding drug testing, particularly for companies that operate in Texas. The purpose of this tutorial is to demystify the legal framework and give a thorough explanation of the state’s modified drug testing requirements for 2024. Knowing your rights and obligations will help you handle this delicate subject with tact and assure compliance.

Part 1: Texas Drug Testing Landscape

Federal versus State Laws:

Understanding the differences between federal and state legislation pertaining to drug testing is crucial. Texas has its own legislation and regulations, although occasionally they are superseded by federal laws, such as those issued by the Department of Transportation (DOT). The stricter rules come into play in these situations.

Statutes and Regulations in Texas:

The main rules regarding drug testing in the workplace are outlined in Texas Administrative Code Title 28, Part 1 and Texas Labor Code Chapter 410. These rules outline testing protocols, employee protections, and acceptable substances (usually cocaine, marijuana, opiates, amphetamines, and phencyclidine). Recall that drug testing procedures may also be affected by court decisions, so it’s important to be updated.

Sector-specific Policies:

Beyond what is required by state and federal law, several industries, such as healthcare and transportation, have additional drug testing requirements. For instance, depending on their license or the regulations of their employers, healthcare personnel may be required to undergo particular tests. Become familiar with any additional rules that may apply to your line of work.

Local Laws:

Although they are rare, municipal ordinances impacting drug testing policies may exist in some Texas counties or cities. Make sure to look up any local laws that might apply to your company or personal circumstances.

Part 2: Types of Drug Testing in Texas

Drug testing before to employment:

Texas allows pre-employment drug testing, but there are restrictions. A documented policy that explains the testing procedure in detail, gets applicants’ informed consent, and makes sure protected groups aren’t unfairly discriminated against is required.

Reasonable Suspicion and Testing Following an Incident:

Justifiable suspicion For an employee to be subject to a drug test, a supervisor must document their suspicion—based on particular facts—that the employee is using drugs. Post-accident testing is also permitted in some circumstances, such as those involving fatalities or major accidents. Texas law requires certain techniques and procedures for both kinds of testing.

Drug testing at random:

In Texas, positions governed by federal agencies such as the DOT that are safety-sensitive are often the only ones subject to random drug testing. It’s a complicated matter with limits and legal constraints for private enterprises. If random testing is being considered, consult legal advice.

Part 3: Employee Rights and Protections

Privatity and Confidentiality:

Employees are entitled to the privacy of their drug test results. With very few exceptions, such as during legal investigations, employers are required to safely and confidentially handle and keep test results.

Lodging and Medical Cannabis:

In certain situations, qualified workers with impairments who use medical marijuana may be eligible for reasonable accommodations. However, Texas’s medicinal marijuana laws are constantly changing, so employers should speak with legal counsel for particular advice.

Refusal to Test and Its Repercussions:

Although it is normally an employee’s right to refuse a drug test, depending on the circumstances and the employer’s rules, this refusal may result in disciplinary proceedings or even termination. Seek specific advice from legal counsel regarding refusals and their ramifications.

Part 4: Best Practices and Considerations

Formulating a Policy for Drug Testing:

A well-written drug testing policy should adhere to pertinent legislation and be unambiguous and consistent. Provide information on things like allowed substances, testing protocols, employee rights, and sanctions for infractions. It is strongly advised that you draft and review your policy with legal assistance.

Speaking and Instruction:

Tell every employee of your drug-testing policy in plain terms. Organize training seminars to make sure everyone is aware of the company’s expectations, the policy, and their rights.

Keeping Current:

Drug testing regulations are always changing, so keep up with any updates or changes at the federal and state levels. To stay up to date on pertinent regulations, make use of services such as legal counsel and the Texas Workforce Commission.


Employers and employees must both be aware of and abide by Texas’s drug testing regulations. While this book offers a broad overview, it is always advisable to get specific legal counsel when handling difficult issues. You may guarantee a responsible and compliant approach to drug testing in the Lone Star State by adhering to best practices and maintaining awareness.
