Facing a Drug Charge in Dallas County?
Deandra Grant Law is a Dallas drug crimes law firm defending drug charges in Dallas and throughout Dallas County, from a first possession case to delivery and trafficking allegations. The Dallas County District Attorney prosecutes these cases through a dedicated drug offenses unit, and every case rests on the same foundation: a lab analysis identifying the substance and its weight. In Dallas that analysis comes from SWIFS, the county’s own forensic institute.
That foundation is exactly where this firm is strongest. Managing partner Deandra Grant holds a Master’s in Pharmaceutical Science and a graduate certificate in forensic toxicology, and both she and partner Douglas Huff are ACS-CHAL Forensic Lawyer-Scientists. We request the chromatograms, the calibration records, and the chain of custody, and the Dallas drug lawyer on your case challenges them at the chemistry level, along with the stop and the search that produced the evidence in the first place. Both partners work eight minutes from Frank Crowley at our Oak Lawn office.
What happens after a drug arrest in Dallas
You are booked at the Lew Sterrett Justice Center and see a magistrate for bond within 48 hours, usually with drug testing as a condition of release. A misdemeanor is filed in a County Criminal Court at Frank Crowley. A felony goes to a grand jury first, often before the SWIFS lab report is back. The defense starts in that gap: the stop, the search, and the chemistry all get examined before the State has finished building its case.

How grading worksWhat Actually Happens After a Drug Arrest in Dallas County
From the booking at Lew Sterrett to the lab report from SWIFS, these are the local specifics that shape a Dallas County drug defense.
Where your case is heard
Misdemeanor drug charges are heard in the County Criminal Courts and felonies in the Criminal District Courts, both at the Frank Crowley Courts Building.
Who prosecutes
The Dallas County District Attorney charges drug cases through a dedicated drug offenses unit. Whatever the substance, the prosecutor across the table works these cases every day.
Your evidence goes to SWIFS
Dallas tests seized substances at the Southwestern Institute of Forensic Sciences. Identity and weight both come from that analysis, and its underlying records are discoverable.
Penalty groups decide the charge
Texas grades drug charges by penalty group and weight. The same conduct can be a misdemeanor or a felony depending on which group the substance sits in, and THC concentrates sit in Group 2.
Texas penalty groups explainedGrand jury review on felonies
Every Texas felony passes through a grand jury before indictment. A defense packet presented at that stage can end a Dallas County drug case before a charge is ever filed.
Possession with intent to deliver
The same baggie becomes a felony one level higher when the State infers intent from packaging, scales, cash, or text messages. No sale has to be proven, and that inference is where the case is fought.
Delivery and trafficking chargesDrug-free zone enhancements
An arrest within 1,000 feet of a school, playground, or youth center adds a mandatory enhancement, and Dallas is dense with them. The measurement and the map are both contestable.
Drug-free zone chargesSimple possession and first offenders
Possession means knowing care, custody, or control, and proximity alone is not enough. The Dallas County DA has publicly declined to prosecute some first-time misdemeanor marijuana and trace-amount cases, and eligibility for diversion or deferred adjudication closes early.
Possession charges and defensesWhat Sets This Defense Apart
What decides a drug case is how well your lawyer understands the evidence.
What We Do on Every Case
From the first call, in order:
- Reach the case before indictment when we can, where a grand jury packet can end it before a charge is filed
- Demand the dash, body, and surveillance video before it’s destroyed
- Pull the full discovery file under Article 39.14: offense reports, witness statements, forensic records
- Examine the forensic evidence ourselves: lab records, chain of custody, the underlying data, not the summary
- Investigate the case the police didn’t: the witnesses never interviewed, the footage never pulled
- File the motions the evidence supports, because suppression is how weak cases end
- Build your mitigation file, with clinical assessments, at no cost to you
- Try the case if the offer isn’t right, which is why the offers get better
We quote a flat fee after a consultation at no cost to you, so the investment is known before you commit.

In the middle of circumstances that doesn't make you proud. Have a supportive and positive lawyer by your side can change the perspective and see your mistakes as an opportunity to learn and grow. Thank you Kevin.
Amazing law practice!! They work so smoothly together!! Highly recommend if you need help getting out of a pickle!!
There aren’t enough words to express how grateful I am for Kevin Sheneberger. From the moment he took my case, he carried the weight of it so I didn’t have to. He handled every detail, kept me informed, and gave me complete peace of mind during one of the most stressful times of my life. I truly felt like I could trust him completely.
Kevin fought for me every step of the way and never stopped working to get the best possible outcome. Because of his dedication, hard work, and knowledge, my DUI case was dismissed, and I avoided a conviction. I honestly couldn’t have asked for a better attorney.
What meant the most to me was that I never felt alone. Kevin genuinely cared about my case, treated me with kindness and respect, and always made me feel like I mattered. He did everything for me, and I never had to worry because I knew my case was in the best hands.
If you’re looking for an attorney who will fight for you, communicate with you, and truly care about getting the best possible result, I wholeheartedly recommend Kevin Sheneberger. He gave me hope when I needed it most and worked tirelessly to give me a second chance. I will never forget everything he did for me, and I will always be grateful. Thank you, Kevin, from the bottom of my heart.
Dallas Drug Crime Attorneys in the Frank Crowley Courts
Deandra Grant, a former Dallas County Assistant District Attorney with a master’s degree in pharmaceutical science, and Douglas Huff, an ACS-CHAL Forensic Lawyer-Scientist with digital forensics training, lead these cases. The Dallas drug crimes attorney on your case appears in the County Criminal Courts and the Criminal District Courts at Frank Crowley every week.
As Seen In
Serving All of Dallas County
We defend drug cases from every corner of Dallas County: Dallas itself plus Garland, Irving, Mesquite, Grand Prairie, Carrollton, Richardson, Rowlett, DeSoto, Duncanville, Cedar Hill, and Lancaster. If the arrest happened in Dallas County, the case lands at Frank Crowley, and that is a building we work in every week. Our Dallas County courts guide walks through the building floor by floor.
Irving and DFW Airport
Irving PD works SH-183, SH-114, and Loop 12, and DFW Airport’s own police make arrests inside the terminals, where a THC vape found at a checkpoint is a regular charge. The airport straddles the Dallas and Tarrant county line, so which side of it you were on decides whether the case goes to Frank Crowley or to Fort Worth. Our DFW Airport vape guide covers those cases, and our Irving DWI lawyer page covers the city’s courts.
Carrollton
Carrollton sits in three counties. A stop on I-35E or the President George Bush Turnpike inside Dallas County is a Frank Crowley case, but the northern parts of the city fall in Denton and Collin counties and are heard there instead. Our Carrollton DWI lawyer page explains how to tell which county has your case.
Richardson
Richardson straddles the Dallas and Collin county line along US-75. South of the line a Richardson PD arrest is a Dallas County case at Frank Crowley. North of it the case is heard in McKinney by the Collin County DA. Our Richardson DWI lawyer page covers both.
Highland Park and University Park
Highland Park is entirely inside Dallas County and is patrolled by its own Department of Public Safety, a combined police and fire agency. Stops on Mockingbird Lane, Preston Road, and the Tollway frontage are Dallas County cases heard at Frank Crowley, and our Oak Lawn office is a few minutes away. See our Highland Park DWI lawyer page.
Garland
Garland PD runs its own detention center, so a Garland arrest is usually held there before the case is filed in Dallas County. I-635, I-30, and the George Bush Turnpike produce most of the city’s stops. The small parts of Garland that cross into Collin and Rockwall counties are heard in those counties.
Mesquite
Mesquite PD and DPS work the I-635, I-30, and US-80 interchange, one of the busiest stretches in the county. Mesquite arrests are Dallas County cases, except for the part of the city that crosses into Kaufman County. Our Kaufman County courts guide covers that docket.
Cedar Hill, DeSoto, and Duncanville
Cedar Hill PD, DeSoto PD, Duncanville PD, and DPS stops on US-67 and I-20 are Dallas County cases like any other. Cedar Hill’s southern edge crosses into Ellis County, where a case is heard in Waxahachie instead. Our Ellis County courts guide covers that courthouse.
Every charge we defend here has its own walkthrough: Dallas Criminal Defense Lawyer, Dallas DWI Lawyer, Dallas Domestic Violence Lawyer, Dallas Assault Lawyer, Dallas Sex Crimes Lawyer, Dallas Theft Defense Lawyer, Dallas Weapons Charge Lawyer, and Dallas Federal Criminal Defense Lawyer. The courthouse, the jail, and the bond process are covered in our Dallas County court guide.
