Cocaine is a Penalty Group 1 controlled substance under Texas Health and Safety Code §481.102. Possession of as little as 1 gram is a second-degree felony. Possession of 4 grams or more is a first-degree felony with a potential life sentence.
Which county handles your case. Frisco straddles both Collin and Denton counties. The county in which the alleged cocaine offense occurred determines which DA’s office prosecutes it and which courthouse hears it. Cases arising in the Collin County portion of Frisco are prosecuted by the Collin County District Attorney’s Office and heard at the Collin County Courthouse, 2100 Bloomdale Road, McKinney, TX 75071. Cases arising in the Denton County portion of Frisco are prosecuted by the Denton County District Attorney’s Office and heard at the Denton County Courthouse, 1450 E. McKinney Street, Denton, TX 76209. Deandra Grant Law has offices in Allen and Denton and handles cases in both counties. If you are unsure which county applies to your case, we will identify it at the outset of the representation.

How Frisco Cocaine Cases Are Processed
Drug specimens seized in Frisco cocaine cases are typically submitted to the DPS Crime Lab in Garland for identification and quantification. The analytical methodology used and the chain of custody from seizure through laboratory analysis are both subject to independent examination.
Both Collin County and Denton County have drug court programs for qualifying defendants, and diversion options may be available in some first-offense cases. Whether diversion is appropriate requires evaluating the specific charge, the defendant’s history, and the strength of the forensic evidence.

The Forensic Science Defense in Frisco Cocaine Cases
Field test reliability. Presumptive field tests are not definitive and are known to produce false positives for cocaine on a range of legal substances. A positive field test is not a conviction.
Weight determinations at threshold values. The penalty tier is driven entirely by weight. Cocaine is commonly sold in mixtures containing adulterants and cutting agents. Whether the DPS lab correctly weighed only the controlled substance mixture (and whether the measurement falls above or below a penalty threshold) is a legitimate forensic challenge, particularly at the 1-gram and 4-gram cutoffs where the margin of instrument error is material.
Laboratory accreditation and protocol. Deviations in sample handling, instrument calibration, analyst qualifications, or chain of custody can render results inadmissible or subject to effective challenge at trial.
Chain of custody. Every transfer of the seized substance (from the arresting officer to the evidence locker to the laboratory) must be documented without interruption. Breaks in the chain of custody create grounds to question whether the substance tested is the same one seized from the defendant.
Article 38.23. Texas’s exclusionary rule carries no good faith exception. Frisco cocaine cases frequently arise from traffic stops on the Dallas North Tollway, Preston Road, SH-121, and Eldorado Parkway. The legality of the stop, the reliability of any CI, and the sufficiency of the warrant affidavit are all examined before any other defense strategy is built.
