Services
Marijuana Defense
Our marijuana defense service protects clients facing possession, distribution, and cultivation charges under Texas' strict laws. We challenge unlawful searches, contest evidence, and negotiate reduced penalties. With specialized knowledge of evolving cannabis regulations, we defend both personal use and commercial operation cases. Our team provides strategic representation for misdemeanor and felony charges, focusing on minimizing long-term consequences to employment and personal freedoms.
Federal Drug Crimes
Federal drug crime defense requires specialized expertise in complex legal procedures. We represent clients facing interstate trafficking, conspiracy charges, and other federal prosecutions. Our approach includes challenging search legality, witness credibility, and evidence chain-of-custody issues. With experience in federal court systems, we develop tailored defense strategies for mandatory minimum sentencing cases and multi-defendant prosecutions involving marijuana and controlled substances.
THC Oil Defense
THC oil defense requires specialized knowledge of Texas' harsh concentrate penalties. We challenge lab testing accuracy, contest unlawful seizures, and defend against felony charges for vape cartridges and dabs. Our team educates clients about Penalty Group 2 classifications and develops strategies for cases where total edible weight determines charge severity. We focus on protecting clients from life-altering felony convictions for small amounts of concentrated cannabis products.
Cultivation Defense
Cultivation defense covers charges related to marijuana plant growth operations. We challenge evidence collection methods, contest plant counts, and defend against commercial intent allegations. Our strategies address indoor/outdoor growing complexities, medical necessity claims, and federal jurisdiction issues. We represent clients facing penalties ranging from misdemeanor possession to first-degree felonies involving large-scale operations and property seizure risks.
Edibles Defense
Edibles defense focuses on Texas' unique legal treatment of THC-infused food products. We challenge cases where entire product weight determines felony severity, contest lab testing errors, and defend against possession charges for low-THC-content items. Our team educates clients about Texas' strict edible classifications and develops strategies for cases involving gummies, brownies, and other infused products that carry harsher penalties than traditional marijuana flower.

Questions
What if I was delivering marijuana for personal use and not for profit?
Even non-commercial transfers can constitute delivery charges. Penalties depend on quantity and whether money exchanged hands.
Will I go to jail if convicted of a marijuana delivery charge?
Misdemeanor charges may result in fines/probation, while felony convictions carry potential jail time depending on amount involved.
Can a marijuana delivery charge be reduced or dismissed?
Yes, through insufficient evidence challenges, rights violations claims, or successful plea negotiations based on case specifics.
What are the legal consequences of possession of THC oil?
THC oil possession automatically constitutes felony charges under Texas Penalty Group 2, with penalties based on total product weight.
Can I fight charges if the police searched my car without a warrant?
Yes, illegal searches without probable cause or warrants can lead to evidence suppression and potential case dismissal.
How can a lawyer help with my THC edibles case?
Attorneys challenge evidence legality, question lab testing accuracy, and develop defense strategies based on case-specific circumstances and constitutional violations.
