    Drug Crime Defense in Dallas

    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.

    Act Early

    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.

    What We Defend

    Dallas Drug Possession and Delivery Charges We Handle

    Every Dallas County drug charge, graded by penalty group and weight.

    Drug Possession

    Possession of a controlled substance, graded by penalty group and weight.

    Possession defense

    Delivery & Trafficking

    Delivery charges rest on intent the State usually infers from packaging and cash.

    Delivery defense

    Marijuana

    Possession charges that now turn on whether the lab can prove THC concentration.

    Marijuana defense

    THC Vapes & Concentrates

    Penalty Group 2 makes a vape pen a felony where a joint is a misdemeanor.

    The concentrate trap

    Methamphetamine

    Penalty Group 1 charges where the lab analysis decides the case.

    Meth charge defense

    Cocaine

    Penalty Group 1 possession, from trace amounts to delivery weight.

    Cocaine defense

    Fentanyl

    Texas now charges some fentanyl deaths as murder, and enforcement is aggressive.

    Fentanyl defense

    Drug-Free Zone

    A zone allegation raises the charge level and restricts probation.

    How grading works
    Local Knowledge

    What 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 explained

    Grand 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 charges

    Drug-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 charges

    Simple 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.

    Meet the Team
    After You Hire Us

    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.

    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.

    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.

    Dallas County

    Dallas Drug Charge Questions, Answered

    Which court will my Dallas drug case be in?

    Misdemeanor drug charges are heard in the County Criminal Courts and felonies in the Criminal District Courts, both at the Frank Crowley Courts Building at 133 N. Riverfront Blvd. Your court assignment appears on your bond paperwork.

    Is a THC vape really a felony?

    It can be. Marijuana flower in a small amount is a Class B misdemeanor, but THC concentrates, including vape pens and edibles, sit in Penalty Group 2, where possession of any usable amount is a felony. The lab's concentration analysis is where that charge is fought.

    The drugs were not mine. Does that matter?

    Possession requires knowing care, custody, or control, and proximity alone is not enough. A shared car or a shared apartment is exactly where these cases get fought, along with how the search happened in the first place.

    What is a drug-free zone enhancement?

    An allegation that the offense happened within a designated zone, such as near a school or playground, raises the charge level and can restrict probation. The measurement and the map are both contestable.

    Can my case be dismissed before trial?

    Some are. Felonies can be no-billed by the grand jury, charges can be rejected or reduced at intake, and suppression of illegally obtained evidence can leave the State unable to proceed. Whether any of those paths is open depends on the evidence, which is why we pull the full discovery file first.

    How much does a Dallas drug lawyer cost?

    It varies with the charge level and whether the case is headed to trial, and we are direct about numbers at the first call. The consultation is free, we offer payment plans, and we quote a flat fee so the investment is known before you commit.

    What happens after a drug arrest in Dallas County?

    You are booked into the Lew Sterrett Justice Center and brought before a magistrate within 48 hours, who sets bond and release conditions that usually include drug testing. A misdemeanor is then filed in one of the County Criminal Courts at the Frank Crowley Courts Building. A felony goes to a grand jury for indictment first, and the SWIFS lab report that confirms the substance and weight can take weeks or months. Your first court setting comes after filing, and the defense work on the stop, the search, and the lab data starts long before it. Our Dallas County courts guide walks through the building.

    Where is the Dallas County jail, and how do I get someone out?

    Dallas arrests book at the Lew Sterrett Justice Center, 111 W. Commerce Street, next to the courthouse. A magistrate sets bond within 48 hours of booking, and the amount and conditions can be argued before that hearing. A bondsman posts a surety bond for a fee; a cash bond is refunded when the case ends. How jail release works in Dallas County.

    Does Dallas County offer diversion for a first drug possession charge?

    Dallas County runs diversion and treatment-court tracks for some first-time and lower-level possession cases, and eligibility turns on the substance, the amount, your record, and the prosecutor’s unit. When it fits, we raise it at the first setting, because a completed program can end with no conviction. It is not the right answer for a case the State cannot prove.

    Can a first possession charge be dismissed?

    Often. A first possession case can end in dismissal when the stop or search does not survive a suppression motion, when the grand jury no-bills a felony, or when the lab work does not hold up. The Dallas County District Attorney has also publicly declined to prosecute some first-time misdemeanor marijuana cases and trace-amount felony cases, though policies change. Where a dismissal is not available, deferred adjudication followed by an order of nondisclosure keeps the case off most background checks. Our possession defenses guide covers each path.

    Will I have to appear at Frank Crowley for every court date?

    Not usually. The first appearance and any plea or trial setting require you in person. Many of the settings in between are announcements your attorney can handle, and we tell you before each one whether you need to be there. Missing a required setting forfeits the bond, so the calendar matters.

    Have a different question? Ask Deandra answers the ones people ask in the first call, and the Dallas County court guide covers the building itself.
