Houston Fentanyl Possession & Distribution Attorney

Fentanyl Possession & Distribution Defense Attorney in Houston, TX

Cory Roth Law Office defends Houston clients facing fentanyl possession, distribution, and manufacturing charges under Texas Penalty Group 1-B (Health & Safety Code §481.1022) and federal law. Our Houston fentanyl defense attorney also represents clients facing first-degree fentanyl murder charges under Texas Penal Code §19.02(b)(4).

What Is Fentanyl Under Texas Law?

Fentanyl is a synthetic opioid that the Texas Legislature has placed in its own dedicated category — Penalty Group 1-B — under Texas Health & Safety Code §481.1022. Penalty Group 1-B contains fentanyl, alpha-methylfentanyl, carfentanil, and every other fentanyl analogue. Because fentanyl is up to 100 times more potent than morphine, Texas treats it more severely than other Penalty Group 1 substances at the manufacture-and-delivery level.

Most Houston fentanyl arrests involve counterfeit prescription pills (often pressed to look like oxycodone, Adderall, or Xanax), powder fentanyl, or fentanyl that has been mixed into cocaine, heroin, or methamphetamine. Trace amounts are enough to trigger Penalty Group 1-B charges because Texas law counts the entire weight of the mixture — including adulterants and dilutants — toward the penalty tier.

Texas Fentanyl Possession Charges & Penalties (§481.115)

In Texas, possessing any amount of fentanyl is a felony. Charges range from a state jail felony for less than one gram to an enhanced first-degree felony carrying up to life in prison for 400 grams or more.

Possession of a Penalty Group 1-B substance is prosecuted under Texas Health & Safety Code §481.115, which was amended in 2023 to expressly include PG 1-B alongside PG 1. The aggregate weight — including any cutting agents or fillers — determines the penalty level.

• Less than 1 gram — State Jail Felony: 180 days to 2 years in state jail and up to a $10,000 fine
• 1 gram to less than 4 grams — Third-Degree Felony: 2 to 10 years in prison and up to a $10,000 fine
• 4 grams to less than 200 grams — Second-Degree Felony: 2 to 20 years in prison and up to a $10,000 fine
• 200 grams to less than 400 grams — First-Degree Felony: 5 to 99 years or life and up to a $10,000 fine
• 400 grams or more — Enhanced First-Degree Felony: 10 to 99 years or life and a fine up to $100,000

Even a single counterfeit pill containing fentanyl can support a state jail felony charge under §481.115. The weight is calculated including any pill binder, lactose, or other adulterant — not just the active fentanyl.

Texas Fentanyl Distribution & Manufacturing Charges (§481.1123)

Manufacture, delivery, or possession with intent to deliver fentanyl in Texas is charged under a fentanyl-specific statute that imposes harsher penalties than other Penalty Group 1 substances. A single gram can trigger second-degree felony exposure.

Unlike other Penalty Group 1 drugs, fentanyl distribution and manufacturing is prosecuted under Texas Health & Safety Code §481.1123 — a separate statute the Legislature enacted to attack fentanyl trafficking more aggressively than methamphetamine, cocaine, or heroin distribution. The penalty tiers begin one degree higher than under §481.112.

• Less than 1 gram — Third-Degree Felony: 2 to 10 years in prison and up to a $10,000 fine
• 1 gram to less than 4 grams — Second-Degree Felony: 2 to 20 years in prison and up to a $10,000 fine
• 4 grams to less than 200 grams — First-Degree Felony: 10 to 99 years or life and a fine up to $20,000
• 200 grams to less than 400 grams — Enhanced First-Degree Felony: 15 to 99 years or life and a fine up to $250,000
• 400 grams or more — Enhanced First-Degree Felony: 20 to 99 years or life and a fine up to $250,000

The State can also prove distribution through possession with intent to deliver — meaning prosecutors don’t need an actual sale. Quantity, packaging, scales, cash, ledgers, and text-message evidence can all be used to argue intent.

Fentanyl Murder in Texas — HB 6 / Penal Code §19.02(b)(4)

A person who knowingly manufactures or delivers fentanyl can be charged with first-degree murder if someone dies after using that substance. The statute does not require proof that the dealer knew a death would occur — only that they knowingly distributed fentanyl.

On September 1, 2023, House Bill 6 added a new theory of murder to Texas Penal Code §19.02(b)(4). The law applies when (1) the defendant knowingly manufactured or delivered a Penalty Group 1-B substance in violation of §481.1123, and (2) an individual died as a result of injecting, ingesting, inhaling, or otherwise introducing that substance into the body — regardless of whether it was used alone or mixed with anything else.

Fentanyl murder is a first-degree felony punishable by 5 to 99 years or life in prison. The Harris County District Attorney’s Office has confirmed it is actively pursuing fentanyl murder charges under HB 6, and additional cases are being filed as overdose investigations work backward from death to supplier.

HB 6 also changed how fentanyl-related deaths are reported. Under Texas Health & Safety Code §193.005(e-1), medical examiners must now record the cause of death as “Fentanyl Poisoning” or “Fentanyl Toxicity” when a toxicology report shows a Penalty Group 1-B substance. That language matters: it shapes the evidentiary record prosecutors use to build a fentanyl homicide case.

Federal Fentanyl Charges in the Southern District of Texas

Federal prosecutors can charge fentanyl offenses under 21 U.S.C. §841 and §846. Federal cases typically arise when:

• The DEA, FBI, HSI, or an OCDETF task force led the investigation
• The case involves a distribution conspiracy across state or international lines
• A controlled buy, wiretap, or cooperating informant was used
• A fentanyl-laced substance caused death or serious bodily injury anywhere in the chain (a federal death-results enhancement triggers a 20-year mandatory minimum)
• A firearm was possessed in furtherance of the offense (18 U.S.C. §924(c) adds 5 to 10 consecutive years)

Federal fentanyl penalties scale by quantity under the federal Controlled Substances Act. Forty grams of fentanyl (or 10 grams of an analogue) triggers a 5-year mandatory minimum; 400 grams (or 100 grams of an analogue) triggers a 10-year mandatory minimum. Sentences are then driven by the United States Sentencing Guidelines, criminal history, and any enhancements. Houston federal cases proceed in the U.S. District Court for the Southern District of Texas. Our firm regularly defends federal drug trafficking and interstate drug trafficking cases in this jurisdiction.

Common Fentanyl Case Scenarios in Houston

Most Houston fentanyl cases come into our office through one of the following fact patterns:

• Counterfeit prescription pills (M30s, fake Adderall, fake Xanax) found during a traffic stop or warrant search
• Powder fentanyl, fentanyl-laced heroin, or fentanyl-laced cocaine seized during a controlled buy
• Postal Inspection Service or HSI interceptions of suspicious packages at Houston ports of entry
• Roommates or vehicle passengers arrested on a constructive-possession theory
• Overdose death investigations where law enforcement uses cell-phone data to identify the alleged supplier
• Wiretap and pen-register evidence supporting conspiracy charges in federal court

Defense Strategies for Houston Fentanyl Cases

Strong defenses depend on the facts, but our firm regularly pursues the following angles in Penalty Group 1-B cases:

Fourth Amendment suppression. Most fentanyl cases start with a traffic stop, a knock-and-talk, or a search warrant. We litigate the reasonableness of the stop, the scope of the search, and the validity of any warrant affidavit. Successful drug search-and-seizure motions can result in evidence suppression and dismissal.

Substance-identification challenges. Field tests for fentanyl are notoriously unreliable. The substance must be confirmed as a §481.1022 fentanyl analogue by a properly accredited lab. Synthetic opioids that field-test positive are not all PG 1-B substances, and a misidentification can collapse the charge.

Weight and adulterant challenges. Texas counts the entire mixture toward the weight tier, but only if every gram of the mixture qualifies as a controlled substance. When fentanyl appears as a trace component of a larger seizure, we challenge whether the State has properly proven aggregate weight.

Knowledge and constructive possession. The State must prove you knowingly possessed fentanyl — not just that it was present in a shared space. Cases involving roommates, passengers, or shared vehicles often turn on the strength of the link between the accused and the substance.

Causation in fentanyl murder cases. Under Penal Code §19.02(b)(4), the State must prove that the substance you delivered caused the death. When the decedent used multiple substances, when significant time elapsed between delivery and death, or when the chain of custody from supplier to decedent is uncertain, causation becomes fertile ground for defense.

Entrapment and confidential-informant attacks. Many Houston fentanyl distribution cases rely on a controlled buy orchestrated by an informant. We scrutinize the informant’s reliability, recorded conduct during the buy, and whether law-enforcement conduct crossed into entrapment.

Federal cooperation and safety-valve eligibility. In federal cases, the 18 U.S.C. §3553(f) safety valve and substantial-assistance reductions under U.S.S.G. §5K1.1 can dramatically reduce exposure for clients with limited criminal history. We evaluate every federal case for both options.

The Good Samaritan Defense (§481.115(g))

Texas law provides a limited defense for a person who calls 911 during an overdose. To qualify under §481.115(g), the person must have been the first to request medical assistance during an ongoing overdose, must have remained on the scene until help arrived, and must have cooperated with responders. The defense does not apply if the actor was committing certain other offenses, has a prior controlled-substance conviction, has already used the defense once, or used the defense within the prior 18 months. The defense applies to the lowest-level possession charges but is unavailable for distribution or manufacturing cases. We frequently raise this defense early to seek dismissal before the case is even indicted.

Collateral Consequences of a Fentanyl Conviction

Even a state jail felony fentanyl conviction triggers consequences that extend well beyond prison time:

• Permanent felony record that appears on background checks for employment, housing, and licensing
• Loss of federal firearm rights under 18 U.S.C. §922(g)
• Suspension or revocation of professional licenses (medical, nursing, legal, real estate, CDL)
• Ineligibility for federal student aid for a period after conviction
• Immigration consequences including removability, inadmissibility, and bars to naturalization
• Driver’s license suspension under Texas Transportation Code §521.372
• Mandatory drug testing, counseling, or treatment as a condition of probation

Because the long-tail consequences are so severe, avoiding conviction is almost always more valuable than negotiating a reduced sentence. Our firm focuses first on suppression, dismissal, and pretrial diversion before considering plea posture.
