A fentanyl pill changes hands between friends, one person dies, and Clark County prosecutors file a murder charge against the survivor instead of a drug charge. That is what a drug-induced homicide charge in Nevada looks like. The statute behind it, NRS 453.333, does not require a drug deal or a dealer. It requires only that someone sold, gave, traded, or otherwise made a controlled substance available, and that the substance caused a death.
We at The Defense Firm represent people charged under this statute across Clark County, and the pattern repeats. Someone who shared a pill, sold a small amount, or handed a friend what they had is suddenly facing the same charge as someone accused of a premeditated killing. This guide covers what the law says, how prosecutors build these cases, where the defense has real leverage, and the one misconception that traps people who did everything right.
Nevada Drug-Induced Homicide Law Under NRS 453.333
Nevada does not have a separate crime called drug-induced homicide. The charge comes from NRS 453.333, a provision inside the state’s controlled substance statutes that reclassifies an overdose death as murder. Prosecutors must prove three things: a death occurred, a controlled substance approximately caused it, and the defendant sold, gave, traded, or otherwise made that substance available to the person who died. Nothing in the statute requires the defendant to be a dealer in the traditional sense, and nothing in it allows victim consent as a defense. A person who willingly took the drug and died from it does not shield the person who supplied it.
This structure puts drug-induced homicide charges Nevada prosecutors file into the same family as felony murder, where a death connected to certain underlying conduct gets charged as murder without any intent to kill. NRS 453.333 sets two degrees. Second degree murder applies by default. First degree murder applies only when the death involves specific aggravating facts tied to trafficking, covered further below. Anyone facing either version of this charge stands before the same courtroom and the same jury pool the firm’s murder defense clients face, not a specialized drug court.
The statute does not distinguish between a street-level dealer and a friend who split a pill with someone at a party. Both fall under the same making available language, which is why the people this law reaches most often are not career traffickers. They are boyfriends, roommates, and friends who had drugs on hand when someone else did not survive taking them.
Clark County Prosecution of Overdose Deaths as Murder
Clark County prosecutors filed murder charges in eight overdose deaths over two years, with about 20 more under investigation, according to a 2022 Las Vegas Review Journal investigation. Those numbers describe a snapshot from early 2022, not a current count, but the trend they document has only grown as fentanyl overdoses climbed. Clark County recorded 64 fentanyl deaths in 2019, 181 in 2020, and 218 in 2021, the same stretch when prosecutors started treating some of those deaths as murder cases instead of accidents.
The Mia Gugino case shows what these filings look like in practice. Gugino died in February 2021, and prosecutors charged Joshua Roberts with both first- and second-degree murder over her death. Jayden Hughes, charged after his girlfriend overdosed on fentanyl pills he had also used himself, resolved his case differently. He pleaded guilty to involuntary manslaughter rather than murder, a lighter charge that shows how much these cases can move once a defense attorney gets involved. Prosecutors build the initial charge around circumstantial evidence, phone records, witness statements, and the toxicology report, and that initial charge is rarely the outcome.
The Nevada Supreme Court expanded the reach of this law in June 2026. It ruled that the state can prosecute a fentanyl seller under NRS 453.333 even when the sale itself happened on tribal land, because the death, the harm the statute punishes, occurred inside Nevada’s territory. The ruling did not change the elements of the offense, but it confirmed that where the fatal overdose happens matters more than where the transaction took place. A defendant cannot assume that a sale made outside Clark County, or even outside standard state jurisdiction, puts a case beyond Nevada’s reach.
Why Many Cases Do Not End in a Murder Conviction
UC Berkeley law professor Jonathan Simon and UNLV law professor Eve Hanan have both raised the same question about these prosecutions. Can a district attorney prove that one specific drug transaction caused a specific death? Does charging the person closest to the body reach the person responsible for the supply chain?
Their skepticism lines up with what the case outcomes show. Filing a murder charge is the easy part for a prosecutor. Proving it beyond a reasonable doubt in front of a jury, against a defense attorney who understands where the state’s causation theory breaks down, is a different matter.
Proving and Challenging Causation in an Overdose Death
Every drug-induced homicide case turns on proximate cause, and that element is also the state’s weakest point in a polysubstance overdose. Medical examiners find more than one drug in a decedent’s system in most overdose cases. Fentanyl mixed with alcohol, benzodiazepines, or another opioid is common. Each additional substance gives a defense attorney a new angle to argue that the substance the defendant supplied was not the actual cause of death. A challenge to the forensic evidence starts with the toxicology report itself: what concentration was found, what that concentration means clinically, and whether the lab’s chain of custody holds up to scrutiny.
Time of death gaps matter just as much as the toxicology numbers. When hours pass between the last known contact with the defendant and the discovery of the body, a defense attorney can raise questions about what happened in between. Did the decedent take an additional dose alone? Can the medical examiner pin the fatal dose to a specific moment at all? A broken link in the chain of custody, from the scene to the lab, gives the defense grounds to challenge whether the tested substance is the one the state blames for the death.
Federal law offers a useful, if limited, comparison. In Burrage v. United States, the U.S. The Supreme Court ruled nine to zero that federal prosecutors must prove a distributed drug was a cause of death when that drug was not independently sufficient to kill on its own. The ruling rejected a looser standard that treated any contributing factor as enough.
Burrage interprets a federal statute, not NRS 453.333, and it is not binding on a Nevada court. Nevada defense attorneys still draw on its reasoning when arguing that a state prosecutor has not met the proximate cause element in a case involving multiple drugs. An expert witness who can explain the toxicology in plain terms to a jury decides whether that argument lands.
Nevada’s Good Samaritan Act and Its Limits
Nevada’s Good Samaritan Drug Overdose Act, codified at NRS 453C.150, protects a person who calls 911 in good faith to report an overdose. That protection covers prosecution for low-level offenses like possession of a controlled substance or drug paraphernalia, and nothing more. Many people believe that protection extends to the person who supplied the drug that caused the overdose. It does not. The immunity was written for possession-level conduct, not for selling, giving, trading, or otherwise making a substance available, which is the exact conduct NRS 453.333 punishes as murder.
This gap catches people at the worst possible moment. Someone shares a pill with a friend, the friend overdoses, and the person who was there calls 911, stays on scene, and cooperates with paramedics and police. That is exactly what every public health campaign tells people to do. That same person can still be arrested for drug crimes tied to supplying the substance, and from there, a murder charge under NRS 453.333 follows if the death connects to what they provided. Understanding this distinction before talking to police, not after, is one of the clearest ways to protect yourself if you were present during an overdose.
Penalties and Defense Strategies for Drug-Induced Homicide Charges
A drug-induced homicide conviction in Nevada carries some of the harshest penalties in the criminal code, because the law treats the overdose death as murder rather than as a drug offense. NRS 200.030(5) punishes second-degree murder under NRS 453.333 as a category A felony: life in prison with parole eligibility after 10 years, or a definite term of 25 years with parole eligibility after 10 years. First-degree murder carries heavier penalties under NRS 200.030(4): life without the possibility of parole, life with parole eligibility after 20 years, or a definite 50-year term with parole eligibility after 20 years. The death penalty applies only when an aggravating circumstance exists, and the defendant carries a qualifying prior or current trafficking conviction under NRS 453.3385, 453.339, or 453.3395. That is why a capital murder defense strategy in these cases starts by attacking the trafficking allegation itself, before it reaches the murder charge.
Two defense theories do most of the work in these cases. The first argues that the substance the defendant supplied did not cause the death, using the toxicology evidence and chain of custody gaps described above. The second argues that the defendant never provided the substance at all, which shifts the case back to the state’s weakest evidence: witness credibility and phone records. A defense strategy built around either theory needs to start before the state locks in its expert witnesses and its timeline. The sooner a defense attorney reviews the file, the more options stay open.
FAQ
Is drug-induced homicide the same as manslaughter in Nevada?
No, manslaughter and drug-induced homicide are separate charges with different penalties. NRS 453.333 charges the death as murder, a category A felony, while involuntary manslaughter carries a shorter sentence. Prosecutors sometimes reduce a drug-induced homicide charge to manslaughter through a plea agreement, as happened in the Jayden Hughes case, but the charge filed at the outset is murder.
Can you be charged if the person who died also used other drugs?
Yes, but a polysubstance overdose gives the defense a stronger argument against proximate cause. If toxicology shows multiple drugs in the decedent’s system, the state has to prove the specific substance the defendant supplied was a cause of death, not just present alongside other substances.
Does calling 911 protect the person who supplied the drug?
Nevada’s Good Samaritan Drug Overdose Act under NRS 453C.150 protects only low-level possession and paraphernalia offenses. It does not shield someone from a murder charge under NRS 453.333 if the substance they supplied caused the death, even if they called for help.
Conclusion
A drug-induced homicide charge can turn a moment involving friends, shared drugs, or an emergency call into a murder prosecution carrying the possibility of decades or life in prison. The state may begin building its case immediately from phone records, witness interviews, toxicology findings, digital messages, and statements made at the scene. Waiting to challenge that evidence gives prosecutors more time to fix their timeline and strengthen their causation theory.
The defense must examine whether the substance attributed to the defendant actually caused the death, whether other drugs or medical conditions contributed, whether the chain of custody is reliable, and whether the state can prove who supplied the substance. These questions can affect whether the case remains a murder charge, is reduced to a lesser offense, or can be challenged before trial.
