Your life just changed forever. That drug possession charge in Texas isn’t just a legal problem—it’s a threat to obliterate your career, destroy your family, and brand you as a felon for life.
The reality? Even less than one gram can mean two years in prison.
Larger amounts? 99 years and $100,000 in fines. Texas doesn’t negotiate on controlled substances.

What Is Possession of a Controlled Substance in Texas?
According to Sections 481.115 through 481.118 of the Texas Health and Safety Code, an individual can be charged with possession of a controlled substance if they knowingly or intentionally possess substances found in Penalty Groups I through IV without a valid prescription from a person licensed to practice medicine.
This broad definition encompasses both actual and constructive possession, making it possible to face charges even when controlled substances aren’t found directly on your person.
- Actual possession occurs when controlled substances are found on your body, in your clothing, or within your immediate reach.
- Constructive possession applies when drugs are discovered in areas you control, such as your vehicle, home, or workplace, even if you weren’t physically holding them.
Common Controlled Substances in Texas
Texas law classifies controlled substances into penalty groups based on their potential for abuse and accepted medical use. Common controlled substances that lead to possession charges include:
- Cocaine and crack cocaine (Penalty Group 1)
- Heroin and fentanyl (Penalty Groups 1 and 1-B)
- Methamphetamine (Penalty Group 1)
- Controlled prescription medications without valid prescriptions (Penalty Group 1 or 3)
- LSD and hallucinogens (Penalty Groups 1-A and 2)
- THC products above legal limits (Penalty Group 2)
Texas Drug Penalty Groups Explained
The Texas Controlled Substances Act categorizes controlled substances into penalty groups, with punishment ranges based on a drug’s danger level and accepted medical use.
These penalty groups include prescription medications, narcotics, stimulants, depressants, hallucinogens, synthetic drugs, and other man-made or natural substances.
Covers the most dangerous and addictive drugs with limited medical use, such as heroin, methamphetamine, codeine, hydrocodone, and cocaine.
| Amount | Offense Level | Prison Term | Fine |
|---|---|---|---|
| < 1 gram | State jail felony | 180 days–2 years | Up to $10,000 |
| 1–4 grams | 3rd degree felony | 2–10 years | Up to $10,000 |
| 4–200 grams | 2nd degree felony | 2–20 years | Up to $10,000 |
| 200–400 grams | 1st degree felony | 5–99 years | Up to $10,000 |
| 400+ grams | Enhanced 1st degree felony | 10–99 years | Up to $100,000 |
Even less than a gram can mean prison time. Many first-time offenders are shocked at how harsh these penalties are—knowing this helps you act fast to protect your record and your freedom.
Applies to LSD and similar hallucinogens (measured in units, not grams).
- < 20 units – State jail felony: 180 days–2 years
- 20+ units – 2nd degree felony: 2–20 years
Prosecutors don’t care if it’s “just a few tabs”—the law treats every unit seriously, and the jump from a minor charge to a major felony happens fast.
Created specifically for fentanyl due to its extreme lethality.
- < 1 gram – State jail felony with enhanced penalties
- Larger amounts lead to higher felony levels with severe sentencing
Note: Dallas penalties depend on both the penalty group and the amount involved.
Dallas prosecutors aggressively pursue fentanyl cases. Even residue can result in felony charges, which is why immediate legal defense is critical.
- Group 2: Includes psilocybin, MDMA (ecstasy), and PCP
- Group 2-A: Covers synthetic cannabinoids and designer drugs.
| Amount | Offense Level | Prison Term | Fine |
|---|---|---|---|
| < 1 gram | State jail felony | 180 days–2 years | Up to $10,000 |
| 1–4 grams | 3rd degree felony | 2–10 years | Up to $10,000 |
| 4–400 grams | 2nd degree felony | 2–20 years | Up to $10,000 |
| 400+ grams | 1st degree felony | 5–99 years | Up to $50,000 |
- Group 3: Prescription drugs like Xanax, Valium, and medications with small amounts of narcotics.
- Group 4: Substances with limited narcotics plus active medical ingredients.
| Amount | Offense Level | Prison/Jail Term | Fine |
|---|---|---|---|
| < 28 grams | Class A misdemeanor | Up to 1 year | Up to $4,000 |
| 28–200 grams | 3rd degree felony | 2–10 years | Up to $10,000 |
| 200–400 grams | 2nd degree felony | 2–20 years | Up to $10,000 |
| 400+ grams | 1st degree felony | 5–99 years | Up to $50,000 |
Group 4 penalties are slightly reduced for < 28 grams (up to 180 days jail and $2,000 fine).
Common Defenses Against Drug Possession Charges in Texas
Drug-Free Zones
Enhanced penalties apply when possession occurs within 1,000 feet of schools, playgrounds, or youth centers.
These drug-free zone violations can elevate misdemeanor charges to felony levels and add additional years in prison to existing felony sentences.
According to Texas Health and Safety Code §481.134, drug-free zone enhancements represent legislative efforts to protect children and educational environments from drug-related crimes.
Previous drug convictions can dramatically increase punishment ranges through Texas’s enhancement statutes. A second felony drug conviction can result in harsher penalties typically reserved for more serious offenses.
While most drug possession charges proceed through Texas state courts, federal prosecutors may pursue charges when drug crime cases involve:
- Large quantities suggest distribution
- Interstate transportation
- Possession near federal property
- Concurrent federal crimes
Federal possession charges often carry longer mandatory minimum sentences and limited opportunities for probation.
If you’re accused of possessing large amounts, authorities may allege intent to distribute—here’s what you need to know about Texas drug trafficking charges.
Our experienced criminal defense attorneys employ various strategies to challenge drug possession charges and protect clients’ rights.
Illegal Search and Seizure
The Fourth Amendment protects against unreasonable searches and seizures. Common violations include:
- Traffic stops without reasonable suspicion
- Home searches without valid warrants
- Consent searches exceeding the granted scope
- Searches incident to invalid arrests
Hypothetical scenario: Police stop a driver for a minor traffic violation and search the vehicle without consent or probable cause, discovering drugs in the trunk. This evidence may be suppressed if the search was conducted in violation of constitutional protections.
Lack of Knowledge or Control
Prosecutors must prove that defendants knowingly possessed controlled substances. Successful possession defense challenges this element when:
- Multiple people had access to the location where controlled substances were found
- Defendants borrowed or shared vehicles containing drugs
- Substances were discovered in common areas of shared residences
This defense is particularly effective when multiple people had access to the location where drugs were discovered.
Invalid Lab Testing and Chain of Custody
Drug evidence must undergo proper testing and maintain an unbroken chain of custody from seizure to trial. Defense challenges include:
- Contaminated or mislabeled samples
- Improper storage procedures
- Gaps in evidence handling documentation
- Unqualified laboratory personnel
Sometimes, even paraphernalia like scales or baggies can lead to criminal charges—read more about Texas paraphernalia laws.
Medical Prescription Defenses
Valid prescriptions provide complete defenses to controlled substance possession charges. However, prescription defenses require:
- Current, valid prescriptions from licensed physicians
- Proper labeling and identification
- Possession within prescribed quantities
Diversion Programs for First-Time Offenders
Texas offers several diversion programs allowing eligible first-time defendants to avoid conviction through completed treatment and supervision.
Contact us to speak with our Texas drug possession lawyers and explore defense strategies tailored to your specific case and circumstances.
Probation and Alternative Sentencing
Texas law provides opportunities for probation and alternative sentencing in many drug possession cases, particularly for first-time offenders.
Under Texas Code of Criminal Procedure Article 42.12, defendants charged with state jail felony drug possession (less than one gram of most controlled substances) are eligible for probation unless they have prior felony convictions.
This mandatory probation provision, found in Health & Safety Code §42.551, recognizes that treatment often proves more effective than incarceration for addressing underlying addiction issues.
Many Texas counties operate specialized drug courts offering intensive supervision combined with treatment services. Successful completion typically results in:
- Dismissed charges upon program completion
- Reduced sentences for participants who struggle but make progress
- Comprehensive support services including counseling and job training
The Texas Office of Court Administration oversees drug court programs across the state, ensuring consistent standards and evidence-based practices.
Deferred adjudication allows defendants to complete probation without entering a formal conviction. Upon successful completion, charges are dismissed, though records may still appear in background checks.
Benefits include:
- No formal conviction on criminal record
- Eligibility for record sealing in some cases
- Opportunity to continue education and employment without felony barriers
First-Time Drug Possession in Texas
First-time controlled substance possession offenses often receive more lenient treatment under Texas law, with several programs designed to prevent minor drug crimes from derailing promising futures.
Penalty Differences for First-Time Offenders
While statutory penalties remain the same regardless of criminal history, first-time offenders benefit from:
- Greater probation eligibility under mandatory probation statutes
- Access to diversion programs is typically reserved for non-violent, first-time drug offenders
- Judicial discretion in sentencing, with many judges preferring treatment over incarceration
Pre-Trial Intervention Programs
Some counties offer pre-trial intervention (PTI) programs allowing charges to be dismissed upon completion of community service, drug education, or treatment requirements.
Hypothetical scenario: A college student faces possession charges after police discover a small amount of marijuana during a dormitory search. Through pre-trial intervention, the student completes drug education courses and community service, resulting in dismissed charges and no permanent criminal record.
What to Do if You're Arrested for Drug Possession
Your actions immediately following a drug possession arrest can significantly impact your case outcome.
- Exercise your right to remain silent beyond providing basic identification information. Statements like “those aren’t mine” or “I didn’t know they were there” can be used against you, even if intended as denials.
- Request our attorney immediately and clearly state: “I want to speak with my lawyer before answering any questions.” Police must cease interrogation once you invoke this right.
- Never consent to searches of your person, vehicle, or property. While officers may search anyway under certain circumstances, your refusal preserves potential Fourth Amendment challenges.
After arrest and release:
- Document everything you remember about the traffic stop or search
- Gather potential witnesses who observed the incident
- Preserve evidence such as prescription bottles or medical records
- Contact our experienced criminal defense attorney before discussing the case with anyone
Avoid discussing your case on social media, with friends, or family members, as these communications aren’t protected by attorney-client privilege.
