A federal drug charge is not a Harris County case with a different courthouse. It is a different legal universe and treating it like a state case is one of the fastest ways to end up in federal prison.
Harris County prosecutors file more than 100,000 criminal cases a year. They are buried in files and have to move volume. The entire Southern District of Texas — 43 counties, from Houston down to Laredo and McAllen — files about 7,274. Federal prosecutors are not managing volume. They have the time, budget, and agents to spend months or years on one case, and the DEA or Homeland Security Investigations may have been building yours long before you knew.
The exposure is real. A single drug quantity can trigger a mandatory minimum prison term that a judge cannot go below without a specific legal reason.
At Keith & Lorfing, we defend federal drug cases in the Southern District of Texas, Houston Division. Our team is led by a former Assistant U.S. Attorney who knows how these prosecutions are built, because he used to build them.
The earlier you have counsel, the more options you have. Speak with a Federal Criminal Defense Lawyer in Houston before you talk to agents, prosecutors, or anyone else about the case.
Federal drug charges we defend in Houston
The Southern District of Texas files roughly 982 federal drug trafficking and conspiracy indictments in a typical year. Immigration cases make up the biggest share of the district’s docket. Set those aside, and drug trafficking accounts for more than 53% of the felonies prosecuted here.
Houston is the reason. The government treats the city as the logistics hub linking the McAllen and Laredo border corridors to the rest of the country. So the cases filed here are rarely street-level possession. They are multi-kilo cocaine, fentanyl, and methamphetamine cases — usually against people the government believes move kilo quantities or have cartel connections.
Federal controlled substances are divided into five schedules based on factors including accepted medical use and potential for abuse. The DEA’s drug scheduling guide explains how those classifications work and which substances fall within each schedule.
Most Houston federal drug cases are charged under a handful of statutes:
- Manufacture and distribution — 21 U.S.C. § 841: The core federal drug statute. It covers making, distributing, or possessing a controlled substance with intent to distribute. Quantity drives the sentence.
- Drug conspiracy — 21 U.S.C. § 846: An agreement between two or more people to commit a drug offense. You don’t have to touch the drugs to be charged — or to be held responsible for the entire load.
- Importation — 21 U.S.C. §§ 952 and 960: Bringing a controlled substance into the United States. Common in a border district like the Southern District of Texas.
- Continuing criminal enterprise — 21 U.S.C. § 848: The “kingpin” statute, aimed at people accused of leading a larger drug operation. It carries some of the harshest penalties in federal law.
Charges are often stacked — a distribution count, a conspiracy count, and sometimes a firearm count under 18 U.S.C. § 924(c) on top. Stacking is deliberate: each count raises the number the government can threaten you with.

Why federal drug charges are so serious
Southern District of Texas · Federal vs. state
Federal drug indictment
In the Southern District of Texas, about 99 of every 100 people indicted on federal drug charges are convicted.
Texas state felony
In state court, nearly half of felony cases end in a dismissal, deferred adjudication, or reduced charge.
Only about 1.2% of federal cases ever reach a jury. The rate is manufactured by guilty pleas.
The mandatory minimum is the main lever. Under § 841, the weight of the drug can lock in a floor of 5 or 10 years in federal prison — before a judge considers anything else about you. About 63% of drug indictments in this district carry one.
That floor is set by quantity, not by your role. A courier and an organizer can face the same starting number if the quantity is the same.
On top of the mandatory minimum sit the U.S. Sentencing Guidelines for federal drug offenses, which are advisory but still shape the outcome. Prior convictions, a firearm, or an alleged leadership role can push the exposure higher.
Federal drug sentences · Southern District of Texas
There is no parole in the federal system. Most people serve at least 85% of their sentence unless First Step Act credits apply.
The consequences reach past prison. A federal drug conviction can bring:
- Forfeiture: The government can move to seize cash, vehicles, and property it links to the alleged offense.
- Immigration consequences: A drug conviction can lead to removal for non-citizens. If immigration status is a concern, our Houston federal immigration defense team can help.
- Loss of rights and licensing: Convictions can affect firearm rights, professional licenses, and future employment.
At sentencing, you don’t just plead — you litigate the math. In a federal drug case that math starts with quantity — and quantity can be fought.
How we defend federal drug cases
You don’t win a federal drug case by waiting for trial, and you don’t win it by playing by the government’s rules. You take the case apart before the government can box you in. There is no single defense, so we build the strategy around the facts — how the investigation was run, what the government can actually prove, and where the sentencing exposure can be reduced.
- Early, pre-indictment intervention: If agents are still investigating, getting involved now can shape the case before charges are filed. Once the government gets there first, you’re reacting instead of deciding.
- Challenging the warrant and the stop: Did the DEA actually have probable cause to search the vehicle, the stash house, or the phone? Traffic stops and warrants have legal limits. When agents cross them, we file suppression motions to keep that evidence out.
- Challenging Title III wiretaps: Federal wiretaps require strict legal necessity — agents must show ordinary investigative methods weren’t enough. If they took shortcuts, the recorded calls may be suppressed.
- Fighting the drug quantity: Drug weight is the engine of a federal drug sentence, and the government’s number is not the last word. We audit the lab purity reports, test how the drugs were weighed, and attack the hearsay ledgers and informant estimates used to inflate the amount attributed to you as “relevant conduct” — including amounts you never personally touched. Pulling that figure down can change the entire sentencing range.
- Attacking conspiracy liability: In a § 846 case, the government must prove you knowingly joined an agreement. We push back on guilt-by-association and on what was reasonably foreseeable to you.
- The safety valve — 18 U.S.C. § 3553(f): This provision can let a judge sentence below the mandatory minimum for certain lower-level, nonviolent defendants who qualify. It requires truthful disclosure to the government, but not the formal cooperation a substantial-assistance deal demands. We work to position eligible clients to use it.
- Sentencing mitigation: Acceptance of responsibility, role reductions, and — when it is genuinely in your interest — cooperation can all lower the final number.
Whether federal drug charges can be beaten depends on what the government can prove, how the evidence was obtained, whether the quantity can be challenged, and whether prosecutors can connect you to the alleged conspiracy.

If you think you are under federal drug investigation
Federal drug cases are often well underway before you feel them. An agency that spent two years building an indictment is not starting from zero when you find out — and what you do in the first days can protect your options or shrink them.
The signs vary: a target letter, a grand jury subpoena, agents at your door, or a co-defendant who suddenly stops talking. However you learn about it, three early mistakes cost people the most.
- Deleting or “cleaning up” anything. Deleting emails or documents doesn’t fix the problem — it creates a new one. Destroying records can add an obstruction charge that is often easier to prove than the drug case itself.
- Putting your head in the sand. Ignoring it while the government keeps building only shrinks your options before you ever react.
- Treating it like a state case. Many defendants — and many state court defense lawyers — handle a federal investigation the way they would a Harris County case. The rules, the timelines, and the leverage are completely different.
If you fear a federal drug investigation, a few steps protect you:
- Hire an experienced federal defense lawyer now — ideally before a subpoena or agents arrive, not a general practitioner.
- Preserve everything. Never delete or alter records; evidence produced strategically through counsel can create leverage.
- Keep government contact controlled. Let your lawyer make first contact, and never rely on an agent’s informal assurances.
Talk to our team before you make a move you cannot undo.
Why choose Keith & Lorfing
When an agency has spent two years building an indictment against you, you can’t afford a lawyer who is learning federal criminal procedure on your dime. You need a team that knows the prosecutors, knows the judges, and knows how the government builds these cases from the inside out.
- A former federal prosecutor leads the team. Managing Partner Russell Lorfing is a former Assistant U.S. Attorney who prosecuted federal cases and has trained DEA, FBI, and IRS agents on evidence. He has seen the charge-stacking playbook from the government’s side. He is admitted in the Southern District of Texas and was selected in 2024 as Co-Chair of the Federal Criminal Defense Committee for the Texas Criminal Defense Lawyers Association.
- A retired federal judge of counsel. Hon. E. Scott Frost (Ret.) brings more than 30 years of federal courtroom experience to our defense team.
- A seasoned trial partner. Founding Partner Trey Keith has spent 20-plus years defending the accused, with many “Not Guilty” verdicts. In a district where only about 1.2% of cases go to trial, a lawyer who will actually try one changes how the government negotiates.
- Team backgrounds you want on your side. Our people include former federal prosecutors and defenders, former FBI agents, and IRS criminal investigators.
We represent clients in federal courts across the country, and we regularly appear in the Houston and Laredo divisions of the Southern District of Texas. Past results do not guarantee any particular outcome in your case.

What to expect in a Southern District of Texas drug case
Houston federal drug cases are handled in the U.S. District Court for the Southern District of Texas, Houston Division, at the Bob Casey U.S. Courthouse on Rusk Street. The district covers 43 counties, and cases that start at the border in Laredo or McAllen often run through Houston. Here is the general path.
- Investigation: The DEA, FBI, or HSI builds the case — often with informants, surveillance, or Title III wiretaps — sometimes for months or years before charges. If agents contact you, read what to do when federal agents want to talk first.
- Charges and initial appearance: You are formally charged by complaint or indictment, then appear before a magistrate judge who decides detention or release.
- Discovery and motions: We review the government’s evidence and file motions — including motions to suppress — to narrow or weaken the case. This is where the warrant, the wiretaps, and the drug weight get tested.
- Resolution: The case ends in a negotiated plea or a trial. With only about 1.2% of federal cases going to a jury, the real fight is usually over the terms of the plea and the sentence. If there is a conviction, sentencing is its own contested proceeding.
These cases don’t move fast on the surface, but underneath they’re moving the entire time — by the time it feels real, it’s usually much further along than you think. For a closer look at the last step, see what to expect at a federal sentencing hearing.

Frequently asked questions
Is my drug charge federal or state?
It depends on who investigated and charged it. Cases involving the DEA or HSI, importation across the border, larger quantities, or multi-defendant conspiracies are often federal. Federal charges carry different — and usually harsher — sentencing rules than Texas state cases.
What are the mandatory minimums for federal drug charges?
Under 21 U.S.C. § 841, drug quantity can trigger a mandatory minimum of 5 or 10 years in federal prison. A judge generally cannot sentence below that floor unless a specific legal exception, like the safety valve or substantial assistance, applies.
Can I avoid the mandatory minimum?
Sometimes. The safety valve under 18 U.S.C. § 3553(f) can let a judge go below the mandatory minimum for certain nonviolent, lower-level defendants who meet its requirements. Whether you qualify depends on the facts of your case, so this is worth reviewing early.
What is a drug conspiracy charge?
A conspiracy under 21 U.S.C. § 846 is an agreement to commit a drug offense. You can be charged even if you were not caught with drugs — the government focuses on the agreement and what was reasonably foreseeable to you.
The DEA wants to talk to me. What should I do?
Talk to a lawyer before you talk to any agent. Anything you say can be used to build the case, and once the government moves first, you end up reacting instead of deciding. Getting counsel involved early can change the outcome.
Where will my federal drug case be heard in Houston?
In the U.S. District Court for the Southern District of Texas, Houston Division, at the Bob Casey U.S. Courthouse, 515 Rusk Street.
Can the drug quantity be challenged?
Yes. Because quantity drives the mandatory minimum and the Guidelines range, how the government measured and attributed the drugs is often a central fight — especially the “relevant conduct” it tries to pin on you, including drugs you never personally handled. Reducing the attributed amount can lower your exposure significantly.
