Texas Drug Trafficking Defense Lawyers

Drug delivery and trafficking charges carry the harshest penalties in the Texas drug offense ladder. Delivery of 400 grams or more of a Penalty Group 1 substance carries a mandatory minimum of 15 years and fines up to $250,000. Every felony level above simple possession begins with the delivery charge, and the prosecution frequently files the highest charge the weight will support.

But the delivery charge is also the charge where the most significant defense challenges exist. The intent to deliver element must be proven beyond a reasonable doubt and that proof is almost always circumstantial. The weight that determines whether the charge is a state jail felony or a first-degree felony is a forensic measurement subject to independent verification. And the laboratory methodology that identifies the substance can be challenged at the chemistry level.

What the Prosecution Must Prove

Texas Health and Safety Code §481.112 et seq. define the delivery offenses by penalty group. “Delivery” is defined under §481.002 as a transfer (actual, constructive, or attempted) of a controlled substance, whether or not there is an agency relationship. It includes actual transfer, constructive transfer, and an offer to sell.

Three separate factual scenarios support a delivery charge, each with different evidentiary profiles:

Actual delivery.  A direct observed transfer typically established through a controlled buy conducted by a confidential informant under law enforcement supervision, or through surveillance of a transaction. The chain of custody for the purchased substance, the reliability of the informant, and the surveillance methodology are all subject to challenge.

Constructive delivery.  A transfer that occurs through an intermediary or through circumstances establishing that the defendant exercised control over the substance that was transferred to another. This is a more legally complex theory that requires the prosecution to establish the defendant’s connection to the transaction through circumstantial evidence.

Possession with intent to deliver.  This is the most frequently charged form and the one most dependent on circumstantial evidence. The prosecution must prove both that the defendant possessed the substance and that they intended to deliver it. The intent element is almost never established through direct evidence. It is inferred from circumstantial factors.

How Intent to Deliver Is Proven — and Challenged

Because defendants rarely make explicit statements about their intent to sell, prosecutors rely on circumstantial evidence to establish the intent element. The defense must evaluate whether each piece of circumstantial evidence actually supports the intent inference or has an alternative innocent explanation.

Quantity.  A quantity of substance that exceeds what a personal user would possess is the most common intent indicator. But personal use quantities vary by substance, by the individual’s tolerance, and by their purchasing patterns. A quantity that would represent weeks of personal use for a heavy user may look like a distribution quantity to a law enforcement officer applying a generalized standard. The defense can present evidence about the defendant’s personal use pattern and purchasing behavior.

Packaging.  Multiple small individually packaged units are presented as consistent with distribution. But individual packaging may also reflect a buyer’s preference for portion control, the way the substance was purchased, or standard retail packaging for legal products being repurposed. Context matters.

Scales.  A digital scale is presented as a tool of the drug trade. But scales are used for cooking, jewelry, fishing, and numerous other legitimate purposes. The presence of a scale alone does not establish intent to deliver.

Cash.  Large amounts of cash are presented as drug proceeds. But cash may reflect legitimate employment, business operations, personal savings preference, or recent withdrawals. The prosecution typically cannot establish that specific cash is drug-related without additional evidence linking it to a transaction.

Communications.  Text messages, call logs, and social media communications that reference quantities, prices, or meetings are frequently used to establish intent. Doug Huff’s Garrett Discovery digital forensics training means these communications are examined for completeness, context, authentication, and attribution — not simply accepted as presented. Ambiguous communications that could reference legal activity are not proof of drug dealing beyond a reasonable doubt.

Absence of paraphernalia.  The prosecution sometimes argues that the absence of personal use paraphernalia (pipes, syringes, rolling papers) supports an inference that the defendant was not a user and therefore must have been distributing. This is a weak inference that the defense can address through evidence about the defendant’s actual consumption methods.

The Weight That Determines the Charge

The penalty level for a drug delivery charge is determined by the weight of the substance and in Texas, that weight includes the entire mixture, not just the pure controlled substance. A gram of methamphetamine cut with a gram of inert cutting agent weighs two grams for penalty calculation purposes, even though it contains only one gram of actual controlled substance.

This mixture-weight rule has significant implications at charge thresholds. A delivery charge that appears to fall just above a felony level boundary deserves independent weight verification. The defense should obtain the laboratory’s complete weight documentation, including the instrument used, its calibration records, and the specific measurement methodology, and have the weight independently verified if it is within the margin of error of a penalty threshold.

The measurement margin of error on analytical balances is a real forensic issue, not a technicality. A measurement of 4.02 grams on a scale with a ±0.05 gram uncertainty means the true weight could be anywhere from 3.97 to 4.07 grams. If the penalty threshold sits at 4 grams, the measurement does not establish beyond a reasonable doubt that the threshold was crossed.

Penalty Structure by Group

Penalty Group 1 — Delivery (§481.112)

Penalty Group 1 includes cocaine, heroin, methamphetamine, oxycodone, hydrocodone (above threshold), and fentanyl.

• Less than 1 gram: State jail felony — 180 days to 2 years, fine up to $10,000.
• 1 to less than 4 grams: Second-degree felony — 2 to 20 years, fine up to $10,000.
• 4 to less than 200 grams: First-degree felony — 5 to 99 years or life, fine up to $10,000.
• 200 to less than 400 grams: First-degree felony, enhanced minimum — 10 to 99 years or life, fine up to $100,000.
• 400 grams or more: First-degree felony, enhanced minimum — 15 to 99 years or life, fine up to $250,000.

Penalty Group 2 — Delivery (§481.113)

Penalty Group 2 includes MDMA/ecstasy, PCP, THC concentrate, and Adderall/amphetamine without prescription.

• Less than 1 gram: State jail felony — 180 days to 2 years, fine up to $10,000.
• 1 to less than 4 grams: Second-degree felony — 2 to 20 years, fine up to $10,000.
• 4 to less than 400 grams: First-degree felony — 5 to 99 years or life, fine up to $10,000.
• 400 grams or more: First-degree felony, enhanced minimum — 10 to 99 years or life, fine up to $100,000.

Penalty Groups 3 and 4 — Delivery (§481.114)

Penalty Groups 3 and 4 include certain prescription medications, compounds with limited controlled substance content, and other regulated substances.

• Less than 28 grams: State jail felony — 180 days to 2 years, fine up to $10,000.
• 28 to less than 200 grams: Second-degree felony — 2 to 20 years, fine up to $10,000.
• 200 to less than 400 grams: First-degree felony — 5 to 99 years or life, fine up to $10,000.
• 400 grams or more: First-degree felony, enhanced minimum — 10 to 99 years or life, fine up to $100,000.

Marijuana Delivery

Marijuana delivery is charged under a separate statutory scheme (§481.120–481.122) and does not follow the penalty group structure above. Delivery of any amount of marijuana is at minimum a Class B misdemeanor, escalating to felony levels based on weight.

Fentanyl: Drug Delivery Resulting in Death

When a person delivers a controlled substance and the recipient dies from using it, Texas Penal Code §19.02 provides a basis for charging the delivery as murder which is a first-degree felony carrying 5 to 99 years or life. This “drug delivery resulting in death” theory has been applied with increasing frequency as fentanyl-related fatalities have increased.

These prosecutions require the prosecution to establish causation (i.e. that the substance delivered by the defendant caused the death) which involves toxicological evidence, medical examiner testimony, and often complex pharmacokinetic analysis. The defense challenges both the causal link and the delivery element itself, which may depend entirely on whether the exchange was characterized as a sale or a shared use between individuals of equal legal culpability.

Drug-Free Zone Enhancements

A delivery offense committed within 1,000 feet of a school, day-care facility, youth center, playground, public pool, or video arcade (or on a school bus) triggers a mandatory enhancement under §481.134 that increases the minimum term of confinement. The enhancement is mandatory and the prosecutor has no discretion to waive it. Geographic proximity is determined at the time of the offense regardless of whether the defendant was aware of the protected zone.

Federal Trafficking Charges

Drug cases involving interstate transportation, federal agency investigation (DEA, HSI, FBI), or quantities triggering federal mandatory minimums may be prosecuted federally under the Controlled Substances Act (21 U.S.C. §841 et seq.). Federal mandatory minimums for drug trafficking begin at 5 years for certain quantity thresholds and escalate to 10 years, 20 years, and life depending on the substance and quantity. Federal sentencing is governed by the U.S. Sentencing Guidelines, and the difference between Guidelines sentencing and a below-Guidelines variance depends heavily on the quality of the defense presentation.
