Drug Trafficking Charges in Texas

Under Texas law, drug trafficking encompasses manufacturing, delivering, or possessing a controlled substance with intent to deliver. Substances commonly charged in trafficking cases include marijuana, heroin, cocaine, methamphetamine, LSD, and anabolic steroids. The full list is covered by the Texas Controlled Substances Act.

Federal trafficking penalties are separate from Texas state penalties and depend on the drug type and quantity involved. For many major controlled substances, a first federal trafficking conviction can carry a minimum of 5 to 40 years in prison and individual fines up to $5 million. A second federal trafficking offense begins at a 10-year minimum with fines up to $8 million. San Antonio’s proximity to the Mexico border means federal law enforcement agencies are often involved in trafficking investigations, which can elevate what begins as a state charge into a federal case.

Marijuana Possession in Texas

Marijuana remains illegal in Texas for recreational use. Possession and trafficking are criminal offenses prosecutable in Texas courts, and a charge today carries real consequences regardless of ongoing legislative debate.

Possessing two ounces or less is a Class B misdemeanor, carrying up to 180 days in jail and a fine up to $2,000. Possession of more than two ounces but no more than four ounces is a Class A misdemeanor. Possession of more than four ounces crosses into felony territory, and possession within 1,000 feet of a school, park, or designated drug-free zone can result in enhanced penalties.

Texas Penalty Groups & Controlled Substances

Texas classifies controlled substances into penalty groups under the Texas Controlled Substances Act, and the group assigned to a substance is the primary driver of charge severity. Knowing which group applies is the first step in assessing a defendant’s exposure.

Penalty Group 1
Cocaine, heroin, methamphetamine, oxycodone, and ketamine fall here. Even small amounts can result in felony charges.

Penalty Group 1-A
LSD and its derivatives make up this group. These substances are measured by abuse units rather than weight, and extremely small amounts can trigger serious charges.

Penalty Group 1-B
Fentanyl and all fentanyl derivatives occupy their own separate penalty group, created specifically to address fentanyl’s unique dangers and carrying enhanced penalties.

Penalty Group 2
MDMA (ecstasy), PCP, psilocybin (mushrooms), and hashish are classified here.

Penalty Group 3
Prescription medications such as Xanax, Valium, Ritalin, and anabolic steroids fall into this group when possessed without a valid prescription.

Bexar County courts handle the full spectrum of penalty-group cases, from misdemeanor marijuana possession to complex Group 1 trafficking charges. Where a substance lands in this classification system determines both the charge a defendant faces and the consequences attached to it.
