When someone dies after using a drug, federal prosecutors can charge the person who distributed it with distribution resulting in death. Under 21 U.S.C. § 841(b), that carries a mandatory minimum of 20 years and a maximum of life, even when the drug quantity is small. These cases have become common with fentanyl.
This guide explains what the government has to prove, the “but-for” causation rule the Supreme Court set in Burrage v. United States, the penalties, and how these cases are defended in the Eastern and Western Districts of Missouri.
The penalty
What is the sentence for distribution resulting in death?
At least 20 years, up to life, regardless of quantity.
No prior drug felony
For a Schedule I or II drug such as fentanyl or heroin, distribution where death or serious bodily injury results from use carries a mandatory minimum of 20 years and a maximum of life.
With a prior
For a person with a prior qualifying drug conviction that has become final, the penalty can be mandatory life imprisonment, if the government properly files notice of the prior.
Serious bodily injury too
The same enhanced penalties apply when the drug causes serious bodily injury, such as a non-fatal overdose requiring emergency treatment, though whether an injury qualifies is often disputed.
No probation
The mandatory minimum applies regardless of how small the sale was, and probation is not available.
Causation
What does “resulting in death” require?
The drug must be a but-for cause of the death.
In Burrage v. United States (2014), the Supreme Court held that the enhancement applies only when use of the drug distributed by the defendant was a but-for cause of the death or injury, at least where the drug was not an independently sufficient cause. It is not enough that the drug “contributed to” the death.
That matters because many overdose deaths involve several substances. If the person had fentanyl, alcohol, and other drugs in their system, the government must prove that, without the defendant’s drug, the person would not have died. The toxicology, the autopsy, and the medical examiner’s reasoning are central.
Because death resulting increases the mandatory minimum, it must be charged and proven to a jury beyond a reasonable doubt, or admitted in a plea.
The chain
How does the government connect a drug to a death?
Through phones, witnesses, and lab work.
These investigations usually begin with the death scene and the decedent’s phone. Texts and call records are used to identify who supplied the drugs, and investigators may then arrange controlled purchases from that person. The government must connect the specific drugs the person used to the defendant, and then prove those drugs caused the death.
Every link can be challenged: whether the defendant was the source, whether the drugs used were the ones the defendant supplied, whether there were other sources, and whether the medical evidence meets the Burrage standard.
Defenses
How do you defend a drug-induced death case?
Causation, identity of the source, and the evidence trail.
- But-for causation. Expert review of toxicology and the autopsy often decides whether the death-results enhancement can be proven.
- The source. Other suppliers, shared drugs, and gaps in time between the sale and the use can break the connection.
- The phone evidence. Whether texts are authentic, who sent them, and what they actually mean.
- The searches. Phone searches and warrants must comply with the Fourth Amendment.
- The charge itself. Without the death-results enhancement, the case is a distribution case with a very different sentencing range, which makes this element the center of negotiations.

FAQ
Distribution resulting in death questions
Can you be charged federally if someone overdoses on drugs you sold?
Yes. If the drug was a but-for cause of the death or serious bodily injury, federal law imposes a 20-year mandatory minimum under 21 U.S.C. § 841(b).
What if the person had other drugs in their system?
Under Burrage v. United States, the government must prove the defendant’s drug was a but-for cause of the death. When several substances were involved, that is often the central dispute.
Does the safety valve apply to distribution resulting in death?
No. The safety valve requires that the offense did not result in death or serious bodily injury.
Is sharing drugs with a friend distribution?
It can be. Distribution does not require a sale, and giving drugs to another person can qualify. The circumstances matter.
Can these cases be charged in state court instead?
Overdose deaths can also lead to state charges. Whether a case is brought in state or federal court depends on prosecutors’ decisions and often on which agency investigated.
