Marijuana Testing Methods & Use Cases

Marijuana testing detects THC metabolites, the compounds the body produces as it processes cannabis. The detection window varies by collection method, which is why we offer urine, hair, saliva, and nail specimen collection at our West Fort Worth location.

Urine testing is the most common choice for workplace screening and reflects more recent use. Hair follicle testing extends that window to roughly 90 days, making it a strong option when a longer lookback period matters. Saliva and nail options round out the panel for situations that call for a different approach.

Panel Options

Marijuana is included in our standard 5-panel drug test alongside cocaine, amphetamines, opiates, and PCP. We also offer 10-panel and 12-panel tests for expanded screening needs. When a result comes back non-negative, confirmation testing is conducted in a GC/MS-accredited laboratory before any final report is issued.

What Fort Worth Employers Should Know About Marijuana Testing

Texas gives private employers broad authority to establish and enforce marijuana drug testing policies. There’s no state law restricting an employer’s right to test, and the Texas Workforce Commission advises that policies be provided to employees in writing and applied consistently and without discrimination.

In September 2025, Texas expanded the Compassionate Use Program through HB 46, increasing the qualifying medical conditions and allowable THC limits under that program. That expansion doesn’t create employee protections against discipline or termination for a positive marijuana test. A positive result under your workplace policy remains an employment matter, not a medical one.

DOT Compliance

For safety-sensitive roles covered by Department of Transportation regulations, such as commercial drivers and pipeline workers, marijuana testing is federally required and isn’t affected by Texas state law or ongoing federal rescheduling discussions. DOT’s 5-panel test includes marijuana regardless of what state law permits.

What Standard Marijuana Tests Detect

Workplace marijuana tests screen for THC metabolites. The test identifies the presence of metabolites, not the specific product consumed, so results don’t distinguish between delta-8, delta-9, or THCA sources. Fort Worth employers should reflect this in their written policies: specify that your policy covers THC metabolites and that consequences apply to test results rather than to any particular product. That framing can reduce ambiguity for both employer and employee when a result is disputed.
