Charged With a Federal
Drug Crime in San Antonio?
Fight Back.
Federal drug charges — conspiracy, possession with intent, trafficking — carry mandatory minimum sentences that can take decades of your life. Attorney Genaro R. Cortez has defended federal drug cases in San Antonio and South Texas for over 20 years, including complex cartel cases, multi-defendant conspiracies, and first-time charges.
Why San Antonio Is a Federal Drug
Prosecution Hotspot
San Antonio sits at the intersection of I-35, I-10, and Hwy 90 — the primary drug corridors connecting Mexico’s border towns of Del Rio, Eagle Pass, and Laredo to the rest of the United States. Federal prosecutors in the Western District of Texas handle more drug cases than almost any other district in the country. The consequences are severe and the prosecutors are experienced. You need an attorney who knows these courts just as well.
Mandatory Minimum Sentences
Federal drug laws require judges to impose minimum prison terms based on drug type and quantity — regardless of your background or role in the offense. A first-time offender convicted on the wrong drug quantity can face 5, 10, or even 20 years in federal prison with no discretion for the judge to go lower.
You Serve 87% — No Early Parole
Unlike state prison, federal inmates serve at least 85-87% of their sentence. There is no parole in the federal system. A 10-year sentence means at least 8.5 years actually served. This makes fighting the charge — and the drug quantity — critically important from day one.
Conspiracy Charges Cast a Wide Net
Under 21 U.S.C. § 846, you can be charged with conspiracy even if no drugs were found on you, even if you only played a minor role, and even if the drug deal never happened. The entire weight of drugs sold by everyone in the conspiracy can be attributed to you — dramatically increasing your sentencing exposure.
Asset Forfeiture
The government can seize cash, vehicles, real estate, and bank accounts connected to alleged drug activity — sometimes before you’re even charged. Acting quickly to protect your assets and retain counsel before forfeiture proceedings begin is essential.
Federal Drug Charges We Handle in San Antonio
📖 For a detailed breakdown of how federal drug conspiracy and possession charges work — including key defenses and legal concepts — read Attorney Cortez’s in-depth guide: San Antonio Federal Drug Attorney: Guide to Conspiracy & Possession.
-
Drug Conspiracy — 21 U.S.C. § 846
Conspiracy is the most commonly charged federal drug offense. The government must prove you knowingly joined an agreement to violate federal drug laws — no drugs need to be found on you. Penalties mirror the underlying drug offense, including mandatory minimums. We challenge the agreement element, knowledge, and your role in the alleged conspiracy.
-
Possession With Intent to Distribute — 21 U.S.C. § 841
The government must prove you knowingly possessed a controlled substance AND had intent to distribute it. Drug quantity triggers mandatory minimums: 500g cocaine or 5g meth triggers 5 years; 5kg cocaine or 50g meth triggers 10 years. We attack knowledge, control, and the government’s drug quantity calculations.
-
Drug Trafficking & Importation
Bringing controlled substances across the U.S.-Mexico border or transporting them interstate triggers federal jurisdiction and enhanced penalties. San Antonio’s position on major drug corridors makes trafficking charges especially common here. We examine the legality of every stop, search, and seizure.
-
Methamphetamine Charges
Meth is the #1 federal drug charge in San Antonio and the Western District of Texas — accounting for nearly half of all federal drug cases. Penalties are especially harsh, tied to both quantity and purity (meth-actual vs. meth-mixture). Safety valve relief and substantial assistance are the primary options for reducing sentences.
-
Cocaine, Heroin & Fentanyl Charges
Powder and crack cocaine, heroin, and fentanyl all carry serious federal mandatory minimums. Fentanyl charges are increasingly common in San Antonio and carry some of the harshest penalties in the federal sentencing guidelines due to its potency and lethality.
-
Continuing Criminal Enterprise — 21 U.S.C. § 848
The “kingpin” statute applies to those who organize, manage, or supervise five or more persons in a continuing series of drug violations. CCE carries a mandatory minimum of 20 years and up to life in prison. We scrutinize whether the government can prove each required element — leadership, five persons, and a series of violations.
-
Drug-Related Money Laundering
Federal drug charges are frequently paired with money laundering charges under 18 U.S.C. § 1956, dramatically increasing sentencing exposure. We defend both the underlying drug charge and the money laundering allegation simultaneously, looking for weaknesses in how the government traces the alleged drug proceeds.
-
Drug + Firearms — 18 U.S.C. § 924(c)
Using or carrying a firearm during a drug trafficking offense triggers mandatory consecutive sentences — 5 years minimum for possession, 7 years for brandishing, 10 years if discharged. These sentences run on top of any drug sentence and cannot be suspended. Early defense is critical.

Federal Drug Mandatory Minimums at a Glance
Federal drug penalties are driven by drug type and quantity. These mandatory minimums are floors — judges cannot go below them without specific exceptions like safety valve relief or substantial assistance. Verify current ranges with your attorney as statutes are subject to change.

Key Defense Strategies in Federal Drug Cases
Every federal drug case has weaknesses. The government must prove every element beyond a reasonable doubt — and experienced defense counsel finds where that burden is not met.
🚫 No Knowledge or Intent
The most common and powerful defense. The government must prove you knowingly possessed drugs or knowingly joined a conspiracy. Someone present at a scene, or unaware of hidden drugs in a vehicle, may not have the required criminal knowledge or intent.
🧍 Mere Presence
Being at a location where drugs are found — a house, car, or warehouse — does not automatically make you guilty. Juries are instructed that mere presence is not sufficient for conviction. We use this defense aggressively in multi-defendant cases.
🛒 Buyer-Seller Exception
A single drug transaction between a buyer and seller does not automatically create a conspiracy. The Fifth Circuit recognizes this exception to protect street-level users from conspiracy penalties intended for large-scale dealers.
📵 Motion to Suppress
If police stopped your vehicle without reasonable suspicion, searched your phone without a warrant, or questioned you without Miranda warnings, we can file motions to suppress that evidence — often the backbone of the government’s entire case.
🌡️ Safety Valve Relief
First-time, non-violent offenders who meet specific criteria can qualify for safety valve relief, allowing a judge to sentence below the mandatory minimum. This is one of the most valuable options available in federal drug cases and requires careful preparation.
🤝 Substantial Assistance — 5K1.1
Cooperating with the government can result in a motion for a significant sentence reduction below the mandatory minimum. This is a complex strategic decision requiring experienced counsel to navigate without creating additional legal exposure.
⚖️ Drug Quantity Challenges
The drug quantity attributed to you drives your mandatory minimum. We challenge the government’s quantity calculations at sentencing — disputing drug lab analysis, attributable amounts, and whether acquitted conduct should be counted.
🚪 Withdrawal from Conspiracy
A conspirator who clearly and explicitly withdraws from the conspiracy and stops participating may limit their criminal liability to the date of withdrawal. This can create a statute of limitations defense if the government filed charges late.
Your Defense, Step by Step
We review the charges, the evidence, your role in the alleged offense, and your criminal history — at no cost. We identify every defense available, including safety valve eligibility, from day one.
We examine every search, seizure, wiretap, informant, and post-arrest statement for constitutional violations. Suppressing key evidence can collapse the government’s case entirely.
Whether fighting at trial, negotiating a favorable plea, pursuing safety valve relief, or evaluating cooperation — we build a strategy specifically tailored to your facts, your goals, and your future.
From bail hearings to sentencing — we stand beside you at every stage in federal court and fight for the best possible outcome. Over 20 years of Western District of Texas experience behind you.
Federal drug cases in San Antonio require an attorney who has spent years in the Western District of Texas courtrooms — not someone learning the system on your case. Attorney Genaro R. Cortez served on the CJA Panel in San Antonio and Del Rio from 2008 to 2025, defending clients charged with some of the most complex federal drug cases in South Texas — including cartel-connected conspiracies, multi-defendant trafficking cases, and first-time offenses.
From challenging the legality of a traffic stop on I-35, to attacking a confidential informant’s credibility, to fighting drug quantity calculations at sentencing that could mean the difference between 5 and 20 years — every detail gets scrutinized. Federal prosecutors in San Antonio are experienced and well-resourced. You deserve defense counsel who matches them.
Federal Drug Defense FAQ
Can I be charged with conspiracy if police found no drugs on me? +
Yes. Under 21 U.S.C. § 846, the government only needs to prove that a criminal agreement existed and that you knowingly joined it. Unlike general conspiracy law, federal drug conspiracy does not require an “overt act” — meaning you can be convicted even if no drugs were ever found on you or seized by police. This is what makes conspiracy charges particularly dangerous and why challenging knowledge and intent is so critical.
What is the “safety valve” and do I qualify? +
The safety valve under 18 U.S.C. § 3553(f) allows a judge to sentence below the mandatory minimum for first-time, non-violent drug offenders who meet specific criteria — including having minimal criminal history, not using violence, not being a leader, and fully debriefing the government. Qualifying for safety valve can be the difference between a mandatory 10 years and a sentence of 4-5 years. Attorney Cortez evaluates safety valve eligibility in every case from the start.
What is a 5K1.1 motion and how does it help? +
A 5K1.1 motion is filed by the government when a defendant provides substantial assistance in the prosecution of others. If granted, it allows the judge to sentence below the mandatory minimum — sometimes dramatically so. Cooperation is a complex strategic decision that must be carefully evaluated with experienced counsel. Providing assistance that is later deemed insufficient, or that creates new legal exposure, can make your situation worse rather than better.
How does drug quantity affect my sentence? +
Drug quantity is the single most important factor driving federal drug sentences. It determines whether mandatory minimums apply, and at what level. In a conspiracy case, you can be held responsible for all drugs handled by every co-conspirator — even drugs you never touched. Challenging the quantity attributed to you at sentencing is one of the most impactful things your attorney can do to reduce your actual sentence.
Can my phone be searched without a warrant during a drug arrest? +
No — under Riley v. California, police must obtain a warrant to search your cell phone incident to arrest. However, if you consent to the search, that consent waives your Fourth Amendment protection. Never consent to a phone search. Cell phone data — texts, GPS pin drops, WhatsApp messages — is often the most damaging evidence in federal drug cases and is used to prove knowledge, intent, and participation in a conspiracy.
What is the difference between meth-actual and meth-mixture? +
Federal sentencing distinguishes between “meth-actual” (the pure drug itself) and “meth-mixture” (the total weight including cutting agents). The penalties for meth-actual are triggered at lower weights — 5 grams of pure meth triggers the same 5-year minimum as 50 grams of mixture. Lab analysis of purity is therefore critically important and can be challenged if the government’s testing methodology was flawed.
Can I get bail in a federal drug case in San Antonio? +
Yes, but it is not automatic. In federal court there is no bail bondsman — you must convince a judge at a detention hearing that you are not a flight risk and not a danger to the community. Drug trafficking charges create a presumption in favor of detention that your attorney must overcome. Having experienced counsel at your detention hearing — ideally your first appearance — significantly improves your chances of pretrial release.
What happens if I was just driving the car and didn’t know about the drugs? +
This is one of the most common situations in San Antonio drug cases involving I-35, I-10, and Hwy 90 traffic stops. The government must prove you had both knowledge of the drugs and control over them. When drugs are hidden in secret compartments — false fuel tanks, hidden panels, spare tires — the Fifth Circuit requires additional evidence beyond your mere presence in the vehicle to establish knowing possession. We fight hard for drivers who genuinely did not know about concealed drugs.
