Drug conspiracy is the most common federal charge we see. In Missouri’s federal courts, it is usually charged under 21 U.S.C. § 846, which punishes an agreement to distribute drugs exactly the same as distributing them, including the same mandatory minimum sentences.
This guide explains what a federal drug conspiracy is, how drug quantity sets a 5- or 10-year mandatory minimum, the ways a sentence can go below that minimum, and what to expect in the Eastern and Western Districts of Missouri.
The charge
What is a federal drug conspiracy?
An agreement between two or more people to distribute, or possess with intent to distribute, a controlled substance.
The agreement is the crime
The government does not have to prove a formal deal, a written plan, or that the person ever personally sold anything. It has to prove an agreement existed, and that the person knew of it and intentionally joined it. The agreement can be inferred from conduct, texts, phone records, and the testimony of other participants.
Same penalties as distribution
Under § 846, a conspiracy carries the same penalties as the offense that was its object. A person charged with conspiracy to distribute methamphetamine faces the same statutory range as a person charged with distributing it.
Conspiracy cases often include many defendants, months of wiretaps or controlled buys, and evidence from cooperating co-defendants. A person who played a small role can be indicted alongside the people at the center of it.
Quantity
What are the federal mandatory minimums for drugs?
Under 21 U.S.C. § 841(b), the drug type and quantity set the floor.
5-year mandatory minimum (maximum 40 years):
- Methamphetamine: 5 grams or more of actual meth, or 50 grams or more of a mixture
- Fentanyl: 40 grams or more of a mixture, or 10 grams or more of a fentanyl analogue
- Cocaine: 500 grams or more; cocaine base (crack): 28 grams or more
- Heroin: 100 grams or more
- Marijuana: 100 kilograms or more, or 100 or more plants
10-year mandatory minimum (maximum life):
- Methamphetamine: 50 grams or more of actual meth, or 500 grams or more of a mixture
- Fentanyl: 400 grams or more of a mixture, or 100 grams or more of a fentanyl analogue
- Cocaine: 5 kilograms or more; cocaine base (crack): 280 grams or more
- Heroin: 1 kilogram or more
- Marijuana: 1,000 kilograms or more, or 1,000 or more plants
If death or serious bodily injury results from use of the drug, the minimum becomes 20 years. A prior conviction for a serious drug felony or serious violent felony can raise the minimums further, to 10 or 15 years with one prior and, at the larger quantities, 25 years with two, but only if the government files a formal notice of the prior under 21 U.S.C. § 851. Probation is not available on a sentence carrying a mandatory minimum.
Because a quantity that triggers a mandatory minimum increases the punishment, it must be found by the jury beyond a reasonable doubt or admitted in a plea (Alleyne v. United States, 2013). In a conspiracy, the quantity is often the most contested fact in the case.
Below the minimum
Can you get less than the mandatory minimum in a federal drug case?
Yes, in two main ways.
The safety valve
Under 18 U.S.C. § 3553(f), the court must sentence under the guidelines without regard to the mandatory minimum if the person meets five conditions: a limited criminal history, no violence or firearm connected to the offense, no death or serious injury, no leadership role, and a truthful disclosure to the government of everything the person knows about the offense, no later than sentencing.
Substantial assistance
If the government files a motion stating that the person provided substantial assistance in investigating or prosecuting others, the court can sentence below the minimum. Only the government can file that motion. Whether to cooperate depends on the strength of the case and the person’s goals, and it is not an option for someone who intends to contest guilt.
The criminal history limit in the safety valve is strict. A person is eligible only if they do not have more than four criminal history points (not counting one-point offenses), do not have a prior three-point offense, and do not have a prior two-point violent offense. The Supreme Court held in Pulsifer v. United States (2024) that failing any one of those three conditions makes the person ineligible. An accurate criminal history calculation, including whether old Missouri convictions are scored correctly, can decide whether the safety valve applies at all.
Sentencing
How is a federal drug sentence calculated?
The mandatory minimum is the floor. The Sentencing Guidelines usually drive the actual number.
The guidelines start with the drug quantity attributed to the person, which in a conspiracy can include amounts handled by others if they were within the scope of the agreement and reasonably foreseeable. They then add or subtract for things like a weapon, the person’s role, and acceptance of responsibility, and combine the result with criminal history to produce a range. The judge must consider the range but is not bound by it.
Much of this is decided by the presentence report. Errors in drug quantity, role, or criminal history can move a range by years, and objections have to be made on time and in the right places.

Defenses
How do you defend a federal drug conspiracy charge?
By testing the agreement, the person’s role in it, and the quantity.
- Buyer-seller, not conspiracy. A simple buyer-seller relationship, without more, is not a conspiracy to distribute. Small personal-use purchases from a dealer are a common example.
- Knowledge and intent. Being present, being related to someone involved, or living where drugs were found does not by itself prove the person joined an agreement.
- Quantity. The quantity that triggers a mandatory minimum must be proven. Estimates based on cooperator testimony are often open to challenge.
- Cooperator credibility. Many conspiracy cases depend on witnesses who are testifying in hopes of a lower sentence. Their deals and their prior statements matter.
- The searches and the wiretaps. Evidence obtained through an unlawful search, or a wiretap that did not meet the statutory requirements, can be suppressed.
FAQ
Federal drug conspiracy questions
What is the sentence for conspiracy to distribute meth?
It depends on quantity and criminal history. Conspiracy carries the same penalties as distribution: a 5-year mandatory minimum for 5 grams of actual meth or 50 grams of a mixture, and a 10-year minimum for 50 grams of actual meth or 500 grams of a mixture. The guidelines often call for more.
Can I be charged with conspiracy if I never sold drugs?
Yes. The crime is the agreement. But the government must prove you knowingly and intentionally joined it, and a simple buyer-seller relationship is not enough by itself.
Who qualifies for the safety valve?
A person with a limited criminal history, no violence or weapon connected to the offense, no death or serious injury, no leadership role, and a truthful disclosure to the government before sentencing. Failing any one of the criminal history conditions makes a person ineligible.
Is there parole in federal drug cases?
No. The federal system has no parole. A sentence is followed by a term of supervised release, which for a 10-year mandatory minimum case is at least five years.
Will I be held until trial on a federal drug charge?
Drug offenses with a maximum of ten years or more carry a presumption of detention, which the defense can rebut. The release plan presented at the detention hearing matters.
