Texas Drug Crime FAQs

Can a drug possession charge be dropped?

The state will drop possession charges for several different reasons. Obviously, if they find during their investigation that they don’t have the evidence, they will drop a charge. Other times, it is a matter of a plea deal. However, the state does not spontaneously drop any charge unless you have an aggressive advocate fighting for you.

Do drug crime penalties vary based on the type of drug?

Yes. Marijuana charges are under an entirely separate class from other charges in Texas. While generally speaking, marijuana charges can be less severe, that’s not saying much. Texas has some of the most strict penalties for possession in the country, with the maximum penalty of life in prison.

What should I do if arrested for a drug crime in San Antonio?

The first and most critical step is to remain calm and exercise your right to remain silent. Avoid providing statements or explanations to law enforcement without legal representation, as anything you say can be used against you. Request to speak with an attorney immediately. Additionally, invoke your right to refuse searches unless a warrant is presented.

How does Texas law classify controlled substances?

Texas law classifies controlled substances into five “penalty groups,” reflecting their potential for abuse and accepted medical applications. Penalty Group 1 entails substances with a high potential for abuse and no recognized medical use, such as heroin and LSD. Penalty Groups 2 through 5 scale down in severity, with Group 2 including drugs like cocaine, which have medical uses but high abuse potential.

What should I expect during the legal process for a drug crime case?

The legal process for a drug crime case typically begins with an arrest, followed by an arraignment where you are formally charged and enter a plea. Depending on the circumstances, pretrial motions and hearings may be held to address issues such as evidence suppression or plea negotiations. If no settlement or plea agreement is reached, the case proceeds to trial, where a judge or jury determines your guilt or innocence.

Can drug charges be reduced or dismissed?

Texas courts may consider charge reduction or dismissal based on various factors. First-time offenders might qualify for pretrial diversion programs focusing on rehabilitation rather than punishment.  Successful completion of drug education or treatment programs can sometimes lead to reduced charges. Procedural errors in the arrest process or evidence collection may also provide grounds for dismissal.
