Motion to Revoke for Positive UA in Corpus Christi: Defending Against Drug Test Violations

A positive drug test while on probation can feel like the end of the road. One moment you are complying with your probation, reporting to your officer, and working toward completing your sentence. The next, you receive notice of a motion to revoke based on a urine analysis that came back positive. Your freedom hangs in the balance. But a positive UA does not have to mean automatic revocation. There are defenses, challenges to the testing process, and strategies that can keep you out of prison and on the path to completing your probation successfully.

At Barton & Associates, Attorneys at Law, we defend individuals throughout Corpus Christi and the Coastal Belt against motions to revoke based on positive drug tests. Whether the test result is accurate, a false positive, or the result of improper testing procedures, we provide the knowledgeable, aggressive representation you need to protect your freedom. With extensive experience in the Nueces County criminal courts, we understand the nuances of drug testing evidence and how to challenge it effectively.

Understanding Probation and Drug Testing

For many individuals on probation, abstaining from alcohol and illegal drugs is a condition of community supervision. This condition is often enforced through random or scheduled drug testing, typically via urine analysis (UA). A positive test result is considered a violation of probation and can trigger a motion to revoke.

The consequences of a positive UA can be severe. If the court finds that you violated your probation by using drugs or alcohol, it may:

• Continue you on probation with additional conditions (more frequent testing, treatment programs)

• Modify your probation to include stricter supervision

• Revoke your probation and impose a sentence of incarceration

For those on regular probation, revocation means serving the original sentence that was suspended. For those on deferred adjudication, revocation means having guilt adjudicated (entering a conviction) and then being sentenced.

Why Drug Tests Are Not Always Accurate

Many people assume that if a drug test comes back positive, the result must be accurate. This is not always the case. Drug tests, including urine analysis, can produce false positives for a variety of reasons:

• Cross-reactivity: Certain over-the-counter medications, prescription drugs, and even foods can cause a false positive result. For example, ibuprofen can cause a false positive for marijuana, and certain antibiotics can cause false positives for opiates.

• Contamination: Improper collection, storage, or handling of the urine sample can lead to contamination and inaccurate results.

• Chain of custody errors: If the sample is not properly tracked from collection to testing, the results may be unreliable.

• Expired or improperly stored test kits: Testing materials have expiration dates and storage requirements. Using expired or improperly stored materials can produce inaccurate results.

• Laboratory errors: Mistakes in the testing process can lead to false positives.

• Passive exposure: Exposure to secondhand smoke or environmental contaminants can sometimes produce detectable levels of substances in urine.

Challenging a Positive UA at a Revocation Hearing

When facing a motion to revoke based on a positive drug test, your attorney can challenge the validity of the test results. Common challenges include:

Challenging the Chain of Custody

The chain of custody is the documented trail of the urine sample from collection to testing. Your attorney can request documentation showing:

• Who collected the sample

• How the sample was labeled and stored

• Who transported the sample

• Who received the sample at the testing facility

• How the sample was stored before testing

• Who performed the test

Any break in the chain of custody can render the test results inadmissible.

Challenging the Testing Methodology

Your attorney can challenge whether the testing methodology was properly followed. This may include:

• Whether the test was performed according to established protocols

• Whether the testing equipment was properly calibrated

• Whether the testing personnel were properly trained

• Whether confirmatory testing (such as GC/MS) was performed on a presumptive positive result

In many cases, initial drug tests are screening tests that can produce false positives. Confirmatory testing, such as gas chromatography/mass spectrometry (GC/MS), is more accurate. If confirmatory testing was not performed, the results may be unreliable.

Presenting Evidence of False Positives

Your attorney may present evidence that the positive result was caused by:

• Legitimate prescription medications

• Over-the-counter medications

• Food or drink (e.g., poppy seeds can cause false positives for opiates)

• Environmental exposure

Medical records, pharmacy records, and expert testimony can support these defenses.

Challenging the Probation Officer’s Observations

The probation officer who collected the sample may have observed irregularities that could affect the result. Your attorney may question the officer about:

• Whether the sample was collected properly

• Whether there were any signs of tampering

• Whether the sample appeared to be adulterated

The Role of Confirmatory Testing

One of the most powerful defenses to a positive UA is the lack of confirmatory testing. Many probation departments use initial screening tests that are designed to be sensitive but can produce false positives. Confirmatory testing using GC/MS is the gold standard for drug testing and can distinguish between actual drug use and innocent causes of a positive result.

If confirmatory testing was not performed, your attorney can argue that the test results are insufficient to prove a violation by a preponderance of the evidence.

Medical Conditions and Prescription Medications

Many legitimate medical conditions and prescription medications can cause positive drug test results. Common examples include:

• Prescription opioids: If you have a valid prescription for pain medication, a positive test for opiates may not be a violation.

• Medical marijuana: Even with a prescription, marijuana use may be prohibited under probation conditions. However, your attorney can argue that the use was for medical purposes.

• CBD products: Some CBD products contain trace amounts of THC that can cause positive test results.

• Antibiotics: Certain antibiotics can cause false positives for various substances.

• Antidepressants: Some antidepressants can cause false positives for benzodiazepines.

If you have a medical condition or are taking prescription medications, it is essential to inform your attorney so they can present this information to the court.

Negotiating a Resolution

Even if the positive UA is valid, a negotiated resolution may be possible rather than a contested hearing. Options include:

Continued Probation with Treatment

You may agree to admit to the violation in exchange for continued probation with additional conditions, such as:

• Enrollment in a substance abuse treatment program

• More frequent drug testing

• Increased reporting requirements

Short Jail Sanction (Shock Time)

You may agree to serve a short period in jail—often 30 to 90 days—and then return to probation. This is sometimes called “shock time” and is intended to deter future violations.

Modification of Probation Conditions

The court may modify your probation conditions to address the underlying substance use issue, such as requiring participation in a recovery program or installation of a SCRAM device for continuous alcohol monitoring.

Dismissal of the Motion

In rare cases, if the violation is minor and you have otherwise complied with probation, the prosecutor may agree to dismiss the motion.

The Importance of Treatment

If the positive UA is accurate and you are struggling with substance use, seeking treatment can be a powerful factor in your defense. The court is more likely to continue probation if you demonstrate a commitment to addressing the underlying issue.

Treatment options may include:

• Outpatient counseling

• Intensive outpatient programs

• Inpatient rehabilitation

• Medication-assisted treatment

• Support groups (AA, NA, etc.)

Documentation of treatment efforts, including attendance records and progress reports, can be powerful mitigating evidence.

Frequently Asked Questions About Motions to Revoke for Positive UA

Can my probation be revoked for a single positive drug test?

Yes. The court has discretion to revoke probation for a single positive test. However, the court may also choose to continue you on probation with additional conditions, particularly if you have otherwise complied and the violation is minor.

What is the difference between a screening test and a confirmatory test?

A screening test is an initial test that is sensitive but can produce false positives. A confirmatory test, such as GC/MS, is more accurate and can distinguish between actual drug use and innocent causes of a positive result.

Can I challenge a positive drug test at my revocation hearing?

Yes. Your attorney can challenge the chain of custody, testing methodology, and whether confirmatory testing was performed. You can also present evidence of false positives, prescription medications, or medical conditions.

What should I do if I receive a motion to revoke based on a positive UA?

Do not wait. Contact an attorney immediately. The sooner you have legal representation, the better your chances of challenging the test results or negotiating a favorable resolution.

Can a prescription medication cause a positive drug test?

Yes. Many prescription medications can cause positive results. If you have a valid prescription, you should provide documentation to your attorney.

Can over-the-counter medications cause false positives?

Yes. Common medications such as ibuprofen, cold medications, and sleep aids can cause false positives for various substances.

What is the chain of custody?

The chain of custody is the documented trail of the urine sample from collection to testing. Any break in the chain of custody can render the test results inadmissible.

What is confirmatory testing?

Confirmatory testing, such as gas chromatography/mass spectrometry (GC/MS), is a more accurate test that can confirm or refute the results of an initial screening test. Without confirmatory testing, a positive screening test may be unreliable.

Can I be revoked for a positive test for a substance I was prescribed?

If you have a valid prescription for the substance, you should not be revoked for using it as prescribed. However, you must provide documentation of the prescription to your attorney and the court.

What is the burden of proof at a revocation hearing for a positive UA?

The state must prove the violation by a preponderance of the evidence (more likely than not). This is a lower standard than beyond a reasonable doubt, but your attorney can still challenge the reliability of the test results.
