San Antonio Drug Crime Defense Attorney

Charged With a Drug Crime in Texas? Serious Charges Require a Serious Defense

If you were arrested for drug possession, distribution, or trafficking in San Antonio or anywhere in Bexar County, the consequences can be severe. Texas drug laws carry significant penalties, including jail time, fines, and a permanent criminal record. At Christian, Nisbet & Casillas, we defend clients facing drug crime allegations throughout San Antonio and the surrounding Bexar County courts.

We Defend Against All Drug-Related Charges

Our attorneys handle a wide range of drug cases at both the state and federal levels, including:

  • Drug possession (misdemeanor and felony)

  • Possession with intent to distribute

  • Manufacturing or cultivation

  • Drug trafficking or conspiracy

  • Prescription drug charges

  • Federal controlled substance violations

We defend cases involving all drug classifications, including marijuana, cocaine, heroin, methamphetamines, fentanyl, ecstasy, and prescription medications like Xanax, Adderall, or Oxycodone.

OUR APPROACH

Strategic and Thorough

At Christian, Nisbet & Casillas, every drug case is met with a tailored defense strategy. We challenge the stop. We question the search. We examine every step for constitutional violations, chain of custody issues, and procedural errors. We work to suppress evidence when possible—and always prepare for trial as if it’s inevitable.

From pre-indictment investigations to federal court proceedings, we are ready to step in at any stage and defend your rights without hesitation.

The Consequences Are Real—and Escalate Fast

DWI charges in Texas carry serious penalties, even for a first offense:

  • Fines up to $2,000 for first offenses (up to $10,000 for felonies)

  • Jail time ranging from 3 days to 10 years

  • License suspension from 90 days to 2 years

  • Installation of ignition interlock devices

  • Permanent criminal record

  • Increased insurance costs and employment barriers

If this is your second or third offense, or if your case involves injury or death, the stakes are significantly higher. Felony charges can lead to extended prison time and long-term loss of rights.

Drug Crimes News & Insights

  • What are the penalties for marijuana possession in Texas?

    Even small amounts of marijuana are illegal in Texas. Penalties include:

    • <2 oz: Class B misdemeanor – up to 180 days in jail, $2,000 fine

    • 2–4 oz: Class A misdemeanor – up to 1 year in jail, $4,000 fine

    • >4 oz: Felony – 2+ years in prison

    Some counties offer diversion programs for first-time offenders, but don’t count on it without legal help.

    Is THC oil, wax, or vape illegal in Texas?

    Yes—and the law treats it more harshly than natural marijuana. Concentrates like THC oil or wax are classified as felony-level Penalty Group 2 drugs, even in small amounts. A vape pen with THC can lead to serious charges and long-term consequences.

    Can I get a drug possession charge dismissed?

    It’s possible. Dismissals may happen due to unlawful searches, insufficient evidence, or eligibility for diversion programs. We examine every angle to get your charges reduced—or thrown out entirely.

    What is a pretrial diversion program and do I qualify?

    Pretrial diversion allows eligible first-time offenders to avoid prosecution by completing probation-like conditions. If successful, your case is dismissed and may qualify for expungement. We’ll assess your eligibility and help you apply if it’s an option.

    What’s the difference between possession and intent to distribute?

    Possession means you knowingly had a controlled substance. Intent to distribute implies you planned to sell or deliver it—based on factors like quantity, packaging, scales, or large amounts of cash. The difference can mean a misdemeanor or a felony.

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

    Yes, but it’s not the end of the story. Prosecutors must prove you had knowledge and control over the drugs. If they were in a shared vehicle, home, or bag, we can challenge the evidence and fight the assumption that you were responsible.

    What is constructive possession?

    Constructive possession means drugs weren’t found directly on you, but in a place you had access to or control over—like your car or room. These cases are highly defensible with the right strategy and investigation.

    Do drug charges affect my ability to get a job or housing?

    Unfortunately, yes. A conviction—even a misdemeanor—can impact employment, housing, student aid, and professional licenses. That’s why we fight aggressively to avoid convictions and clear your record where possible.

    Will I go to jail for drug possession in Bexar County?

    Jail is possible, but not guaranteed. Outcomes depend on the type and amount of drug, prior history, and available diversion options. We fight to keep you out of jail and preserve your future.

    How can Christian, Nisbet & Casillas help me fight drug charges?
