Drug enforcement in Dallas has intensified—and prosecutors are pursuing these cases aggressively.

Arrests remain consistently high, and sentences are getting tougher. If you’ve been charged, you’re not just dealing with a single allegation—you’re facing a system built to secure convictions. But these cases can be challenged.

At the Law Offices of Richard C. McConathy, we understand how Dallas drug cases are built—and where they can break down. If you’re facing charges, working with an experienced Dallas drug defense lawyer can make a critical difference in your case.

Why Drug Enforcement in Dallas Is Intensifying

Federal Focus on the I-35 Corridor

The I-35 corridor through Dallas-Fort Worth is a major drug trafficking route connecting Mexico to the entire United States. Federal agencies including the DEA, ATF, and Homeland Security Investigations maintain a permanent presence on I-35, conducting vehicle searches, investigations, and arrests.

The I-35 Corridor Task Force operates checkpoints and conducts surveillance specifically targeting drug traffickers. This federal presence means that drug offenses on or near I-35 can result in federal charges, which carry mandatory minimums and much harsher penalties than state charges.

If you’re arrested on I-35 or in areas where the I-35 corridor intersects with Dallas (North Dallas, near DFW Airport), you may face federal prosecution in addition to state charges.

Local Task Force Operations

The Dallas Police Department Narcotics Division works closely with federal agencies through the North Central Texas High Intensity Drug Trafficking Area (HIDTA) program. This coordination creates comprehensive investigation networks that are difficult to fight alone.

HIDTA task forces conduct undercover operations, surveillance, and buy-bust stings. They maintain informant networks that provide intelligence on drug distribution in neighborhoods throughout Dallas. They conduct controlled deliveries and intercept packages.

This coordinated enforcement means drug cases are built methodically with multiple layers of evidence and investigative steps. Single-officer cases are rare. Most cases involve multiple agencies, multiple officers, and comprehensive evidence gathering.

Public Health Emergency Declaration

Several Texas leaders have declared methamphetamine and fentanyl as public health emergencies. This declaration has led to increased funding for drug enforcement, specialized training for officers, and political pressure on prosecutors and judges to pursue maximum sentences.

Judges, knowing they’re under public pressure to address the drug crisis, are imposing harsher sentences. Prosecutors, knowing they have voter support for tough-on-crime approaches, are less willing to negotiate and more likely to seek prison time.

Rise of Fentanyl Trafficking

Fentanyl has replaced heroin as the primary opioid trafficked in Dallas. Fentanyl is exponentially more potent and deadly than heroin, and law enforcement treats fentanyl cases as emergencies.

A single pill or a few grams of fentanyl can be fatal. A tiny amount (fentanyl is measured in micrograms, not grams) constitutes a prosecutable offense. The danger of fentanyl has led to enhanced enforcement and harsher penalties.

Methamphetamine Distribution Networks

Methamphetamine is manufactured, distributed, and consumed in Dallas at alarming rates. Unlike heroin or cocaine, which are imported, meth is often produced locally in hidden labs or through more sophisticated operations.

Dallas law enforcement has made methamphetamine enforcement a priority because of the connection between meth and violent crime, property crime, and neighborhood deterioration. Neighborhoods with high meth use see increases in robbery, burglary, and assault.

How Drug Enforcement Works in Dallas

Undercover Operations and Buy-Bust Stings

Federal and local narcotics units conduct undercover operations where officers pose as drug users or dealers. These operations are designed to get suspects to sell drugs directly to undercover officers.

Buy-bust operations involve an undercover officer approaching you (or an informant setting you up) to purchase drugs. Once you hand over the drugs and money changes hands, you’re arrested immediately.

These operations are complex and often involve entrapment defenses, but prosecuting agencies rarely make mistakes that rise to entrapment level. The evidence in buy-bust cases is usually strong because it’s controlled from start to finish.


Informant Networks and Controlled Buys

Federal agencies maintain networks of confidential informants (CIs) who provide intelligence on drug distribution. Informants are often people arrested for drug crimes who trade information (and testimony) for reduced sentences.

Informants conduct controlled buys—purchasing drugs from suspects while wearing a recording device. These buys are recorded and documented as evidence. Informants also provide information about drug houses, distribution patterns, and supplier networks.

Informant testimony is often credible in court because the informant is incentivized to provide accurate information (to get their own sentence reduced). Challenging an informant’s credibility is difficult but sometimes successful.

Mail and Package Interdiction

Federal agencies conduct surveillance of mail and package delivery services, looking for packages containing drugs. These operations target both incoming packages and packages being mailed out.

Mail interdiction often occurs at post offices, FedEx facilities, and UPS stores. If a package is suspected of containing drugs, it’s seized and opened (with a warrant) for testing. The sender is then arrested.

Mail interdiction cases are particularly complex because they involve Fourth Amendment issues, mail privacy laws, and proving who sent or ordered the package.

Electronic Surveillance and Phone Records

In sophisticated drug investigations, federal agencies obtain wiretap warrants allowing them to monitor phone calls and text messages. These wiretaps can monitor an entire drug distribution network.

Phone records, including calls, texts, and location data, are also obtained through subpoenas. These records show communication patterns and locations during suspected drug transactions.

Electronic surveillance creates comprehensive evidence of drug distribution conspiracies, making defense particularly challenging.

What Happens When You’re Arrested

Initial Arrest and Questioning

After arrest, police will take you to a Dallas Police Department facility or a federal facility (if it’s a federal case). You will be offered an opportunity to speak with police. Do not do this. Request an attorney immediately and remain silent.

Police interrogation in drug cases is designed to get you to admit to possession, to identify sources (where you got the drugs), and to implicate others in distribution. Anything you say will be used against you and potentially against others.

Bail and Bail Conditions

For federal drug cases, bail is often higher because judges are concerned about flight risk for serious drug offenses. For state cases in Dallas County, bail for drug possession is typically set between $1,000 and $5,000, depending on the amount and your criminal history.

For distribution cases, bail is much higher—$10,000 to $25,000 or more. Federal drug cases often result in bail being denied entirely, requiring you to remain in custody throughout trial.

Our attorneys argue for bail at the initial appearance, presenting evidence of your ties to Dallas, employment, and stable housing.

Search of Your Home or Vehicle

If police have a warrant to search your home or vehicle, the search will be executed and documented. Even if police conduct an illegal search without a warrant, evidence found is usually used against you anyway, with the charges being subject to challenge in court later.

If your home or vehicle is searched, document the condition before and after, take photographs, and note anything damaged or taken. This evidence is useful in challenging the search or seeking civil remedies.

Testing and Lab Reports

All suspected drugs are sent to a laboratory for testing and analysis. The lab identifies the substance, confirms it’s a controlled substance, and determines the weight or quantity.

Lab reports are usually available within weeks or months. We review these reports carefully, challenging them if procedures weren’t followed properly or if testing was incomplete.

Defenses Against Drug Charges in Dallas

Motion to Suppress Illegal Searches

If police searched your home, vehicle, or person without a warrant or without valid consent, all evidence from that search must be suppressed. Once evidence is suppressed, prosecutors often have no case.

We aggressively file motions to suppress in every case where the search is questionable.

Challenging Lab Results

Lab testing can be inaccurate, samples can be contaminated, and procedures can be improper. We challenge lab results if:

  • The chain of custody is broken (samples were mishandled or lost track of).
  • Testing procedures weren’t followed properly.
  • The sample was contaminated or degraded.
  • The lab technician didn’t properly document the analysis.
  • The substance identification is questionable.

Proving Lack of Knowledge or Possession

If you didn’t know you had the drug, or didn’t have control over it, possession charges can fail. In cases involving shared vehicles, shared apartments, or situations where the drug belonged to someone else, we argue you didn’t know about it.

Challenging Informant Credibility

Informants are often people with criminal histories who are motivated by reduced sentences. We investigate the informant’s background, history of reliability, and incentive to testify. If the informant has lied before or has a strong motivation to frame you, their testimony is less credible.

Entrapment Defenses

If an undercover officer induced you to commit a drug crime you wouldn’t otherwise have committed, entrapment might be a viable defense. Entrapment occurs when government action creates a substantial risk that an innocent person will commit a crime.

Entrapment is difficult to prove, but we explore it aggressively when the facts support it.

Negotiating Reduced Charges

Based on our investigation and the strengths and weaknesses of the prosecution’s case, we negotiate with prosecutors for reduced charges, dismissed counts, or alternative outcomes.

A felony distribution charge might be negotiated to a misdemeanor possession charge. A charge involving a large amount might be reduced to a smaller amount (lower felony degree). Multiple charges might be consolidated into a single charge.

The Role of Federal Task Forces

If your case involves federal agencies (DEA, ATF, Homeland Security, FBI), the case is likely prosecuted in federal court. 

Federal drug cases carry mandatory minimum sentences:

  • Possession with intent to distribute: minimum 5 years
  • Drug trafficking (larger amounts): minimum 10 years
  • Drug trafficking (very large amounts): minimum 20 years

Federal judges have less discretion in sentencing because of mandatory minimums. Federal prosecutions are also more thorough and complex, often taking years from arrest to trial.

Federal cases require specialized legal expertise. We have experience with federal drug cases and understand federal procedures, discovery rules, and sentencing guidelines.

Protecting Your Rights Immediately After Arrest

Remain Silent

Do not answer police questions. Police are trained to get you to incriminate yourself. Your only statement should be: “I want to speak with an attorney.” Then remain completely silent.

Police will ask to search your home, vehicle, or person. You can refuse. Say: “I do not consent to a search.” If police search anyway, we can challenge it in court.

Request an Attorney

Request an attorney immediately and before any questioning. Once you’ve requested an attorney, police must stop questioning until your attorney is present.
