“Heroin” – Laws, Penalties & Best Defenses in Nevada

Under Nevada heroin laws, knowingly possessing, selling, or trafficking heroin is generally a felony. Being under the influence is generally a misdemeanor.¹

First-Time Penalties

• Simple possession (NRS 453.336): For less than 14 grams, a category E felony, which should end in a dismissal upon completion of the court’s requirements.
• Possession for sale (NRS 453.337): A category D felony, carrying 1 to 4 years in prison and a possible fine of up to $5,000. Probation may be available.
• Sale or distribution (NRS 453.321):  A category C felony, carrying 1 to 5 years in prison and a possible fine of up to $10,000.²

Defenses (depending on the charge)

• Lack of possession
• No intent to sell
• Unlawful police search
• Entrapment

Our approach in these cases is to examine whether the police found the drugs unlawfully, whether the evidence points to another suspect, and whether the lab results call the charge into question. We also look for opportunities to obtain dismissal through treatment.

1. Heroin Crimes

Each heroin crime in Nevada has its own elements that prosecutors need to prove to obtain a conviction.

• Simple possession:  You knowingly had heroin under your actual control (such as in your pocket) or constructive control (such as in your safe) or joint control (with someone else).
• Possession for sale: You possessed heroin with the purpose of selling it. Prosecutors do not have to prove a completed sale.
• Sale or distribution: You sold, transported, supplied, or gave away heroin. Payment is not always necessary.
• Trafficking: You did any of the above with at least 100 grams of heroin.³

In a shared home or car, we examine who used the area where police found the drugs, who owned the container, and what the witnesses actually saw. Being nearby does not, by itself, establish that you knowingly possessed someone else’s heroin.

2. Penalties

Heroin is classified as a schedule I controlled substance, which means it has a high potential for abuse and no accepted medical use in treatment in the United States. Therefore, heroin crimes can carry very stiff penalties in Nevada.

Nevada heroin penalties depend on the offense, quantity, and qualifying prior convictions. The tables below show the usual statutory ranges. Additional charges or sentencing enhancements can change the outcome.

Possession

Nevada’s punishments for heroin possession for personal use (NRS 453.336) depend on the quantity and your criminal history.⁴

Heroin Possession	Nevada Penalties
Less than 14 grams: qualifying first or second offense	Category E felony:  Typically a dismissal after completion of a deferred judgment.
Less than 14 grams: third or subsequent offense	Category D felony:  1 to 4 years in prison and a possible fine of up to $20,000.
14 grams to less than 28 grams	Category C felony:  1 to 5 years in prison and a possible fine of up to $10,000.
28 grams to less than 42 grams	Category B felony:  1 to 10 years in prison and a fine of up to $50,000.
42 grams to less than 100 grams	Category B felony:  2 to 15 years in prison and a fine of up to $50,000.

Probation may be possible depending on the case.

Possession for Sale and Selling

Heroin possession with the intent to sell (“possession for sale) under NRS 453.337 and selling, giving away, or transporting heroin under NRS 453.321 are separate offenses in Nevada. The usual penalties are as follows.⁵

Heroin Crime	Nevada Penalties
Possession for sale	First Offense:  Category D, carrying 1 to 4 years in prison; possible fine up to $5,000. Second Offense:  Category C, carrying 1 to 5 years in prison; possible fine up to $10,000. Third or Subsequent Offense:  Category B, carrying 3 to 15 years in prison; possible fine up to $20,000.
Selling, giving away, or transporting	First Offense:  Category C, carrying 1 to 5 years in prison; possible fine up to $10,000. Second Offense:  Category B, carrying 2 to 10 years in prison; possible fine up to $20,000. Third or Subsequent Offense: Category B, carrying 3 to 15 years in prison; possible fine up to $20,000.

Probation may be available for a first offense. For the repeat-offense tiers, the court generally must find mitigating circumstances before granting probation.

Certain sales and related offenses on or within 1,000 feet of schools, public parks, youth recreational centers, and other listed locations can carry an additional consecutive prison term under NRS 453.3345.⁶

Trafficking

Heroin trafficking under NRS 453.3385 generally begins at 100 grams. The statute includes mixtures containing heroin, so the prosecution does not have to show 100 grams of pure heroin.⁷

Quantity	Trafficking penalties
100 grams to less than 400 grams	Category B felony: 2 to 20 years in prison and a fine of up to $100,000.
400 grams or more	Category A felony: Life in prison with parole eligibility after 10 years, or a 25-year sentence with parole eligibility after 10 years, and a fine of up to $500,000.

Trafficking sentences generally cannot be suspended, and the mandatory minimum must be served before parole eligibility. However, NRS 453.3405 permits a reduction or suspension when the court finds that the defendant provided substantial assistance in investigating or prosecuting an offense.

If heroin is mixed with illicitly manufactured fentanyl, separate fentanyl trafficking provisions can apply at 28 grams. This is another reason we review the laboratory findings and the precise statute charged rather than rely on a police report’s label.

Being Under the Influence

Under NRS 453.441, unlawful use or being under the influence of heroin is generally a misdemeanor. This carries up to six months in jail and/or $1,000 in fines.

DUI

In Nevada, driving under the influence of heroin is generally a misdemeanor under NRS 484C.110 and NRS 484C.400. A first-time conviction typically carries:

• 2 days to 6 months in jail;
• $400 to $1,000 in fines plus costs;
• DUI School;
• Victim Impact Panel; and
• 185-day driver’s license revocation.

A prior felony DUI, a third DUI within seven years, or a DUI causing death or substantial bodily harm would instead trigger felony charges.⁸

3. Defenses

Here at Las Vegas Defense Group, we have represented literally thousands of people charged with crimes involving drugs, including heroin. In our experience, the following four defenses have proven very effective with prosecutors, judges, and juries in getting Nevada heroin cases reduced or dismissed.

1) No knowing possession

You are not automatically guilty because someone left heroin in your car or home. The state must establish knowing possession. We look for evidence that another person controlled the drugs or that you did not know they were there.

Useful evidence may include messages, witness accounts, body-camera recordings, and information showing who had access to the room, vehicle, or container.

2) No intent to sell or low quantity

Police often presume drug suspects intended to sell if they were carrying cash or a gun. Though unless the D.A. can prove intent to sell beyond a reasonable doubt, which is a much higher bar than the standard required for an arrest, the charge should be reduced to simple possession.

Similarly, police sometimes make mistakes when identifying and weighing drugs. We have gotten trafficking cases reduced to simple possession by showing that the police in fact seized less than 400 grams of drugs.

3) Unlawful police search

If police found the heroin through an unlawful search, then we can ask the court to exclude (“suppress“) the heroin from evidence. If the court agrees, the D.A. may be left with too weak of a case to continue prosecuting.

In the 2023 case McCord v. State, the Nevada Supreme Court reversed a drug trafficking conviction after rejecting the alleged license-plate violation used to justify the traffic stop. The officer could have identified the required registration information despite the plate frame.⁹

We use that kind of close review to compare the officer’s stated reason for a stop with the video, photographs, and governing law. McCord involved methamphetamine, but its traffic stop analysis would matter in a heroin case too.

4) Police entrapment

Entrapment occurs when the government presents a criminal opportunity to someone who was not predisposed to commit the crime. Police are allowed to go undercover in attempt to catch suspects, but it becomes entrapment if they use undue pressure, such as threatening to hurt someone if they refuse to share their drugs.¹⁰

In these cases, we examine the complete messages and recordings, including any reluctance you expressed and how the officer or informant responded.

4. Drug Court, Dismissal, and Plea Bargains

For a qualifying first or second personal possession offense involving less than 14 grams of heroin, a Nevada court must defer judgment with your consent under NRS 453.336(2)(a) and NRS 176.211. This generally involves entering a qualifying plea while the court postpones judgment.¹¹

The court may then require treatment, testing, supervision, or a Drug Court program. Once it finds that you completed the conditions, it must discharge you and dismiss the proceedings. Failing the program can lead to renewed prosecution.

Separately, a prosecutor may agree to a plea bargain reducing a felony charge to a misdemeanor under NRS 454.351. It carries up to six months in jail and/or a fine of up to $1,000.¹²

We evaluate dismissal options before recommending a plea. When treatment is appropriate, we help present a workable plan and explain what you must complete to earn dismissal.

5. Record Seals

Many Nevada heroin cases can be sealed, but the waiting period for filing a petition to seal depends on the final conviction and how the case ended. The general rules are as follows.¹³

Case Outcome	Nevada Record Seal Wait Time
Misdemeanor (not including DUI)	1 year after release from custody or the end of the suspended sentence, whichever is later.
Category E felony	2 years after release from custody or discharge from parole or probation, whichever is later.
Category B, C, or D felony	Generally 5 years after release from custody or discharge from parole or probation, whichever is later.
Category A felony	Generally 10 years after release from custody or discharge from parole or probation, whichever is later.
Misdemeanor DUI conviction	7 years after release from custody or the end of the suspended sentence, whichever is later.
Felony DUI conviction	Generally not sealable.
Dismissed charge or acquittal	Generally no waiting period.
Successful deferred judgment under NRS 176.211	Generally sealed automatically.

We recommend pursuing a record seal as soon as you are eligible (unless the court automatically sealed it as part of a deferred judgment). Having a drug conviction on your criminal record can greatly hinder your ability to obtain employment, housing, an education, or loans.

6. Immigration Consequences

A Nevada heroin-related controlled substance conviction can make a noncitizen deportable.¹⁴

A Nevada dismissal after a guilty plea and court-ordered conditions may still count as a conviction under federal immigration law. Avoiding prison or sealing the state record does not necessarily solve the immigration problem.¹⁵

Before recommending a plea, we consider whether we can challenge the charge or negotiate an outcome that better protects your immigration status, with immigration counsel involved when appropriate.

Frequently Asked Questions

Is heroin possession a felony in Nevada?

Yes. Unlawful heroin possession is generally a felony under NRS 453.336. A qualifying first or second offense involving less than 14 grams is a category E felony, with deferred judgment available as required by law. Larger amounts or qualifying prior drug convictions can lead to more serious felony charges.

We check whether prosecutors can prove that you knowingly possessed the heroin and whether they charged the correct quantity and offense level. We also assess your eligibility for a dismissal through deferred judgment.

Will I go to jail for a first heroin possession charge?

Not necessarily. For a qualifying first or second personal-possession offense involving less than 14 grams, Nevada requires deferred judgment with your consent, subject to statutory eligibility rules. Completing the court’s conditions leads to dismissal. Different rules apply to larger quantities, possession for sale, and trafficking.

We first check the quantity, your prior record, and the evidence against you. Then we evaluate whether to seek dismissal on legal grounds or pursue an eligible treatment-based resolution.

How much heroin counts as trafficking in Nevada?

Heroin trafficking generally starts at 100 grams, including qualifying mixtures containing heroin. You can face trafficking charges based on knowing possession alone, even without a sale. Separate fentanyl laws can apply at lower quantities when the mixture contains illicitly manufactured fentanyl.

We examine the lab report, the weighing process, and the evidence connecting you to the drugs. The amount listed in a booking report is not a substitute for reviewing the prosecution’s proof.

Can I be convicted if the heroin belonged to someone else?

You can possess drugs belonging to someone else if you knowingly control them. However, simply being in the same car or home does not automatically establish knowing possession.

We investigate who controlled the area and whether there is evidence that indicates you were unaware of the heroin. Shared access can be important when challenging the prosecutor’s assumptions.

Is giving heroin to a friend a crime if no money changes hands?

Yes. NRS 453.321 prohibits giving away and supplying controlled substances, as well as selling them. A first heroin offense under that statute is generally a category C felony carrying 1 to 5 years in prison and a possible fine of up to $10,000.

Does being high on heroin automatically mean felony possession?

No. Unlawful use or being under the influence is generally a misdemeanor under NRS 453.411. A separate possession charge requires proof of possession, and driving under the influence is governed by different statutes.

Will finishing Drug Court protect me from deportation?

Not necessarily. A guilty plea followed by treatment, probation, or other court-ordered conditions may count as a conviction under federal immigration law, even if Nevada later dismisses the case.
