Finding the Drug Is Only Part of the Story.

A drug arrest is overwhelming. The charges feel certain, the consequences feel inevitable, and the case feels lost before it starts. None of that is true.

Drug charges are built on evidence that’s gathered quickly, often without the full picture, and presented to prosecutors before the defense has an opportunity to examine it. The fact that drugs were found doesn’t answer the questions that actually matter. The search still has to be lawful. The evidence still has to be reliable. And the State still has to prove knowledge and intent beyond a reasonable doubt.

At Denuna & Westbrook, PLLC, we represent individuals facing drug charges throughout Houston and the Gulf Coast region. We examine the evidence, the investigation, and every element the State is required to prove.

How Texas Classifies Controlled Substances

Texas law classifies controlled substances into penalty groups under Chapter 481 of the Texas Health and Safety Code, commonly referred to as the Texas Controlled Substances Act. The penalty group assigned to a substance, along with the alleged quantity and a person's criminal history, determines the severity of the charge and the potential punishment range.

Penalty Group	Common Substances	Charge Range
Group 1	Heroin, cocaine, methamphetamine, fentanyl, oxycodone	State Jail Felony to First-Degree Felony
Group 1-A	LSD	State Jail Felony to First-Degree Felony
Group 2	MDMA (ecstasy), PCP, psilocybin (mushrooms)	State Jail Felony to First-Degree Felony
Group 2-A	Synthetic cannabinoids (K2, Spice)	Class B misdemeanor to First-Degree Felony
Group 3	Prescription stimulants, benzodiazepines, anabolic steroids	Class A misdemeanor to Third-Degree Felony
Group 4	Compounds containing small amounts of narcotics	Class B misdemeanor to Third-Degree Felony

Understanding which penalty group applies and how the alleged quantity affects the charge is the first step in evaluating any drug case. The same substance can produce very different charges depending on the amount alleged, and those differences can mean the difference between a misdemeanor and a serious felony.

Possession Offenses

Possession of a controlled substance is charged under Health and Safety Code Sections 481.115 through 481.118, depending on the penalty group involved. A first-time possession charge involving a small amount of a Penalty Group 1 substance is a State Jail Felony. As the alleged quantity increases, so does the charge, potentially reaching a First-Degree Felony with a punishment range of five to ninety-nine years.

Delivery and Manufacturing Offenses

Delivery and manufacture of a controlled substance carry significantly higher penalties than possession alone. These offenses are charged under Health and Safety Code Sections 481.112 through 481.114. Even a small-quantity delivery of a Penalty Group 1 substance is a Second-Degree Felony, with higher ranges applying as the alleged quantity increases. Manufacturing allegations, including those involving labs or production facilities, fall under the same statutory framework and can result in First-Degree Felony charges.

One of the most contested issues is whether possession was actually intended for distribution rather than personal use. The State must prove intent to deliver through circumstantial evidence, typically the quantity of the substance, packaging materials, scales, cash, cell phone data, or other surrounding circumstances. Those factors may be relevant, but none of them answers the question on its own. Each one can be explained, contextualized, or challenged. The leap from possession to delivery is a significant one, and assumptions about intent deserve scrutiny before they’re accepted as actual proof.

Prior Convictions and Punishment Enhancement

Prior felony convictions can dramatically increase your exposure in a drug case. Under Texas Penal Code Section 12.42, a prior felony conviction can enhance the punishment range of the current offense, elevating a Second-Degree Felony to a First-Degree Felony. Two prior felony convictions may result in a habitual offender finding with a punishment range of twenty-five to ninety-nine years or life.

Prior drug convictions may also affect your eligibility for diversion programs and other favorable resolutions. Your criminal history shapes the current charge in ways that aren’t always obvious. That analysis, and what it means for your current case, starts on day one.

The Issue of Possession

Texas law requires the State to prove that you exercised actual care, custody, control, or management over a prohibited substance. Proximity isn’t enough. Being near drugs, or being present where drugs are found, doesn’t establish possession on its own.

Drugs may be found in vehicles with multiple occupants, homes shared by several people, hotel rooms, backpacks, and containers that more than one person had access to. In these situations, the State must do more than point to the drugs and then point to you. Prosecutors must establish specific “affirmative links” connecting you, and not someone else, to the illegal substance.

Constitutional Limits on Obtaining Drug Evidence

In many drug prosecutions, the central issue is how law enforcement found the drugs.

Law enforcement must comply with constitutional protections governing searches and seizures. Drug investigations arise from traffic stops, vehicle searches, consent searches, search warrants, anonymous tips, and surveillance operations. When constitutional requirements aren’t followed, the evidence may become inadmissible.

Some of the most significant defense issues in drug cases involve:

• Whether the initial detention was lawful
• Whether officers had legal authority to conduct the search
• Whether your consent to search was truly voluntary
• Whether the search warrant was supported by probable cause
• Whether officers exceeded the scope of their authority

When the evidence forms the foundation of the prosecution, problems in the investigation may substantially affect the State’s ability to proceed.

Search Warrants and Drug Investigations

Many drug cases are built entirely on evidence obtained through a search warrant. A warrant isn’t a formality. Law enforcement must present specific and sufficient facts to a Magistrate to establish probable cause, and those facts must be accurate. When they aren’t, the warrant and the evidence it produced become vulnerable to challenge.

The Four Corners Rule

When the defense challenges whether a search warrant affidavit establishes probable cause, courts are generally limited to what appears within the “four corners” of the affidavit itself. The Magistrate who signed the warrant reviewed what the officer put in the affidavit – that’s it. If that affidavit is legally insufficient to establish probable cause on its face, the warrant fails, and the evidence obtained may be suppressed.

Common problems within the four corners of a warrant affidavit include conclusions without supporting facts, stale information that no longer supports a finding of probable cause, failure to establish the reliability of a confidential informant, and descriptions of the place to be searched or items to be seized that are too vague to meet constitutional requirements.

Franks Hearings: Challenging the Truthfulness of the Affidavit

When the problem goes beyond the face of the affidavit, the defense may pursue a Franks hearing. Under Franks v. Delaware, 438 U.S. 154 (1978), a defendant is entitled to a hearing on the truthfulness of the warrant affidavit when the defense makes a substantial preliminary showing that the affiant knowingly, intentionally, or with reckless disregard for the truth included a false statement in the affidavit, and that false statement was necessary to the finding of probable cause.

At a Franks hearing, the defense presents evidence challenging the accuracy of the affidavit. If the court finds the affidavit contained knowing or reckless falsehoods and that the remaining content is insufficient to support probable cause, the warrant is voided and the evidence suppressed.

Issues that commonly support a Franks challenge include:

• Material facts omitted from the affidavit that would have defeated probable cause
• Inaccurate descriptions of the controlled buy or surveillance
• Reliance on a confidential informant whose reliability was not accurately represented
• Stock or boilerplate language included in the affidavit that did not reflect the actual facts of the investigation
• Officer conclusions presented as facts without the underlying observations to support them

The Motion to Suppress

When constitutional violations occur during a drug investigation, the defense can file a Motion to Suppress, asking the Court to suppress the illegally obtained evidence. A successful suppression motion can eliminate the foundation of the prosecution’s case. When the drugs themselves are the primary evidence, suppression can effectively end the case.

Texas Code of Criminal Procedure Article 38.23 also provides that evidence obtained in violation of state or federal law may not be used against the accused, and that the jury may be instructed on this issue if a fact question exists about whether the evidence was legally obtained. That instruction, when given, places the constitutional issue directly in front of the jury.

When a search warrant forms the foundation of your case, a thorough review of the warrant application, the supporting affidavit, the execution of the warrant, and the circumstances of the investigation are key issues to review and challenge.

Facing Life on a Major First-Degree Felony. The Search Warrant Changed Everything.

In a recent Harris County case, our client faced a First-Degree Felony prosecution involving numerous allegations of possession, distribution, and manufacturing. The potential exposure included life in prison.

After a thorough review of the search warrant, the supporting affidavit, and the circumstances surrounding the investigation, Denuna & Westbrook, PLLC identified significant flaws in how the warrant was obtained. Those issues became the foundation of our defense strategy.

We spent over 12 months negotiating with different prosecutors, repeatedly challenging the warrant, and forcing the State to confront the critical issues at every stage of the negotiation. Our persistence paid off. The State ultimately agreed to five years of deferred adjudication probation, a resolution virtually unheard of on a First-Degree Felony of this magnitude.

The facts of this case weren’t favorable, and the evidence was substantial. When we first reviewed the case, prison time seemed inevitable. The only question was how much. What changed everything was a single issue: what law enforcement did before they ever entered our client’s home.

This result was extraordinary. If our client successfully completes the probation, he will avoid a felony conviction entirely, saving his life and future. That result came from identifying one constitutional issue early in the case and refusing to let prosecutors ignore it at any stage of the negotiation.

Confidential Informants

Many drug investigations rely on information from confidential informants. Some provide tips used to initiate an investigation. Others participate in controlled purchases, assist with surveillance, or supply information used to obtain a warrant.

Informant information isn’t automatically reliable. Informants cooperate for their own reasons: avoiding prosecution, receiving favorable treatment in their own cases, earning compensation, or obtaining some other benefit. Those motivations directly affect their credibility.

When your case rests on informant cooperation, we examine the circumstances surrounding the investigation, what information the informant provided, whether that information was independently corroborated, and whether the investigation complied with constitutional requirements. Cases that initially appear strong sometimes reveal significant credibility issues after a thorough review.

Consequences Beyond the Criminal Case

A drug conviction reaches further than the criminal penalty. Employment, professional licensing, housing, immigration status, and driving privileges can all be affected by a conviction that has nothing to do with those areas of a person's life. Understanding the full scope of consequences before any resolution is accepted is part of building a complete defense.

Driver’s License Suspension

A drug conviction in Texas can suspend your driver's license even when the offense had nothing to do with driving. Under Texas Transportation Code Section 521.372, a final conviction for a drug offense triggers a license suspension. The current suspension period is 90 days from the date of conviction. If you don't yet hold a Texas driver's license at the time of conviction, DPS can deny issuance for the same period.

A few important distinctions:

• Felony drug convictions trigger mandatory suspension with no judicial discretion
• Misdemeanor drug convictions carry some flexibility. Courts may waive the suspension for a first offense if you have no prior drug conviction within the past 36 months, but that waiver is discretionary, not guaranteed
• A prior drug conviction within 36 months eliminates the possibility of waiver entirely. Suspension becomes mandatory
• If your license was already under suspension at the time of conviction, DPS may not reinstate it even after the suspension period ends

Getting your license back requires completing a drug education course, submitting a certificate of completion to DPS, obtaining SR-22 insurance coverage, and paying a reinstatement fee. The SR-22 requirement stays in place for two years from the date of conviction.

If you need to drive for work, school, medical appointments, or essential household responsibilities, an Occupational Driver's License may be available. The license suspension is a collateral consequence that can affect your employment, your family, and your daily life long after the criminal case is resolved.

Immigration Consequences

For non-citizens, a drug conviction can be more devastating than the criminal sentence itself. Drug offenses are among the most serious deportation triggers under federal immigration law, and the consequences apply regardless of how long a person has lived in the United States, whether they have family here, or what the circumstances of the offense were.

A guilty plea or no contest plea in a Texas drug case is treated as a conviction under federal immigration law, regardless of how Texas classifies the outcome. This means deferred adjudication is not a safe harbor for non-citizens. A person who pleads guilty, receives deferred adjudication, completes probation, and has the case dismissed may still face deportation based on the underlying plea.

The immigration consequences of a drug conviction can include:

• Deportation or removal from the United States
• Inadmissibility, making it impossible to reenter the country legally after leaving
• Denial of naturalization or citizenship applications
• Mandatory immigration detention pending removal proceedings
• Permanent bars to reentry for convictions classified as aggravated felonies under federal law

Drug paraphernalia convictions also trigger immigration consequences under federal law, even though they are often treated as minor offenses in the criminal system. The specific substance, the specific charge, and how the case is resolved all affect the immigration outcome. Some resolutions are significantly safer than others for non-citizens, and identifying those options requires understanding both the criminal defense and the immigration implications simultaneously.

If you are not a U.S. citizen and you are facing a drug charge, getting immigration counsel involved alongside criminal defense counsel is not optional. It is essential. The decisions made in the criminal case will directly affect your immigration status, and those consequences may be irreversible.

Employment, Licensing, and Housing

A drug conviction creates obstacles that follow a person long after the criminal case is resolved.

Many employers conduct background checks and may decline to hire applicants with drug convictions. Professional licenses in fields including healthcare, law, education, finance, and transportation can be suspended, revoked, or denied based on a drug conviction. Housing applications that require background checks may result in denials. Federal student financial aid may be affected for convictions occurring while enrolled.

Before accepting any plea agreement, it’s essential to understand these consequences and how they may impact your future.

Defending Drug Charges: Constitutional Challenges and Scientific Evidence

Constitutional challenges shape drug defense more than almost any other area of criminal law. Search and seizure issues, warrant validity, the reliability of informants, and suppression motions frequently become the most important issues in your case.

Denuna & Westbrook, PLLC has represented clients facing drug charges at every level, from misdemeanor possession to serious First-Degree Felony allegations. Chris Denuna's background as a Forensic Lawyer-Scientist provides additional experience when drug cases involve laboratory results, toxicology evidence, or questions about the identification and classification of a substance.

Our approach is consistent in any drug case, whether misdemeanor or felony: examine how the evidence was obtained, challenge what doesn’t hold up, and hold the State to its burden of proof on every element.

Frequently Asked Questions — Drug Crimes in Texas

Can I be charged with possession if the drugs weren’t mine?

Yes. But the State must prove more than your presence near a substance. Prosecutors must establish a meaningful connection between you and the alleged contraband. Proximity isn’t enough.

What determines whether my charge is a misdemeanor or felony?

The type of substance, the alleged quantity, and the nature of the alleged conduct — possession, delivery, or manufacturing — all affect the classification. The penalty group assigned to the substance under Chapter 481 of the Health and Safety Code determines the starting point.

What is intent to deliver?

Intent to deliver is an allegation that drugs were possessed for distribution rather than personal use. The State relies on circumstantial evidence to make this argument, and those conclusions are frequently disputed.

What if the drugs were found in a vehicle or residence I shared with others?

Shared-access cases create significant possession issues. Prosecutors must prove more than proximity and must connect you specifically to the substance.

Can an illegal search lead to dismissal of my case?

Potentially. If evidence was obtained in violation of your constitutional rights, the defense may seek suppression. In some cases, successful suppression challenges substantially weaken or eliminate the prosecution’s ability to proceed.

Will a drug conviction suspend my driver’s license?

Yes, in most cases. Felony drug convictions trigger mandatory automatic suspension. Misdemeanor convictions may be waived by the court if you have no prior drug offense within 36 months, but that waiver isn’t guaranteed. Reinstatement requires completing a drug education course, SR-22 insurance, and a reinstatement fee.

Will a drug conviction affect my immigration status?

Drug convictions can carry serious immigration consequences, including deportation, inadmissibility, and denial of naturalization. If you are not a U.S. citizen, this issue deserves immediate attention as part of your defense strategy.
