Drug Crime FAQs
What types of defenses are available?
Common defenses include:
- Challenging possession: Actual vs. constructive possession
- Unlawful search and seizure: Lack of probable cause or invalid warrants, especially during traffic stops
- Negotiating plea bargains, Diversion programs, or pursuing trial if the evidence is weak
How do drug convictions affect my life beyond legal penalties?
- Employment: Convictions may trigger job loss or disqualification during background checks.
- Housing: Landlords often deny rentals based on convictions.
- Education: colleges may suspend, expel, or deny admission due to criminal records.
- Professional licensing & insurance: Convictions can hurt licenses and require SR‑22 insurance.
Are prescription drugs treated the same as illegal drugs?
Yes and no. Unauthorized possession of prescription medications (like Xanax, Adderall, or OxyContin) is illegal and can result in misdemeanor or felony charges, depending on the drug and quantity. However, having a valid prescription provides a legal defense.
Can a drug conviction be expunged in Texas?
Possibly. If your case was dismissed, you completed a diversion program, or you received deferred adjudication (and meet specific conditions), you may be eligible for expungement or non-disclosure. A lawyer can help evaluate your eligibility and guide you through the process.
Will a drug charge affect my immigration status?
Yes. Non-citizens (including lawful permanent residents) may face deportation, visa revocation, or denial of naturalization due to drug convictions. Even misdemeanor offenses like marijuana possession can have serious immigration consequences.
Does Texas offer drug court as an alternative to jail?
Yes. Dallas County Drug Court offers certain non-violent drug offenders the opportunity to enter treatment programs instead of serving jail time. Successful completion can lead to reduced charges or dismissal, but eligibility is limited and must be approved by the court.
