New Hampshire Drug Laws: Penalties, Charges & Treatment Options

New Hampshire's drug laws are codified primarily in the Controlled Drug Act, RSA Chapter 318-B. The state classifies controlled substances into five schedules (I through V), with the Commissioner of the Department of Health and Human Services authorized to schedule, reschedule, or remove substances under RSA 318-B:1-a based on criteria established in RSA 318-B:1-b, including abuse potential, accepted medical use, and dependence liability.

The Controlled Drug Act prohibits the manufacture, sale, dispensing, possession with intent to distribute, and simple possession of controlled substances without lawful authorization (RSA 318-B:2). New Hampshire distinguishes between manufacturing and distribution offenses (RSA 318-B:26, I), which carry the most severe penalties including potential life imprisonment when death results, and simple possession offenses (RSA 318-B:26, II), which are generally classified as felonies for Schedule I-IV substances and misdemeanors or violations for marijuana depending on quantity.

In 2017, New Hampshire partially decriminalized possession of small amounts of marijuana under RSA 318-B:2-c, making possession of 3/4 ounce or less a civil violation rather than a criminal offense. The state also operates a Therapeutic Cannabis Program under RSA 126-X for qualifying patients. Drug-free school zone enhancements under RSA 318-B:26 double the penalties for offenses committed within 1,000 feet of a school, with a mandatory minimum of one year imprisonment. The state has increasingly focused on combating the fentanyl and opioid crisis through expanded naloxone access, Good Samaritan protections, drug checking legislation, and proposed mandatory minimum sentencing for fentanyl offenses.

New Hampshire penalizes drug possession under RSA 318-B:26, Section II. The severity of the penalty depends on the drug schedule and whether it is a first or subsequent offense.

Schedule I, II, III, or IV Substances (RSA 318-B:26, II(a)): Any person who knowingly or purposely obtains, purchases, transports, or possesses a controlled drug or analog classified in Schedules I through IV commits a class B felony, punishable by up to 7 years in prison and a fine of up to $25,000. A second or subsequent offense is a class A felony carrying up to 15 years in prison and a $50,000 fine. A mandatory minimum fine of $350 applies to all first offenses, and $500 for subsequent offenses.

Schedule V Substances (RSA 318-B:26, II(b)): Possession of a Schedule V substance is a misdemeanor carrying a maximum sentence of 3 years imprisonment and a $15,000 fine.

Marijuana — 3/4 Ounce or Less (RSA 318-B:2-c): Effective July 2017, possession of 3/4 ounce or less of marijuana (or 5 grams or less of hashish) is a civil violation, not a criminal offense. The fine is $100 for a first or second offense and $300 for a third offense. A fourth or subsequent offense within 3 years may be charged as a class B misdemeanor. A court shall waive the fine for a single violation within a 3-year period upon proof of completing a substance abuse assessment within 60 days.

Marijuana — More Than 3/4 Ounce (RSA 318-B:26, II(c)): Possession of more than 3/4 ounce of marijuana or more than 5 grams of hashish is a misdemeanor punishable by up to 1 year in jail and a $350 fine. A subsequent offense may carry up to 6 years imprisonment and a $50,000 fine.

Drug-Free School Zone Enhancement (RSA 318-B:26, III): Possession of controlled drugs within 1,000 feet of a school or on a school bus subjects the offender to a mandatory minimum of 1 year imprisonment and a potential fine of up to $500,000 or 5 times the street value of the drug, whichever is greater.

New Hampshire's DWI statute, RSA Chapter 265-A, makes it illegal to drive, operate, or attempt to operate a motor vehicle while under the influence of intoxicating liquor, controlled drugs, or any combination thereof (RSA 265-A:2). Impairment can be established through behavioral evidence or per se blood alcohol concentration (BAC) levels.

BAC Limits: 0.08% for standard drivers (RSA 265-A:2, I(b)); 0.04% for commercial vehicle operators; 0.02% for drivers under 21 (zero tolerance).

First Offense (Class B Misdemeanor): Fine of $500 to $1,200; 9- to 24-month license revocation (6 months may be suspended upon entry into the Impaired Driver Intervention Program within 45 days); no mandatory jail time for a standard first offense.

Aggravated DWI (RSA 265-A:3): A person commits aggravated DWI with a BAC of 0.16 or more, by causing a collision resulting in serious bodily injury, or by driving with a passenger under age 16. Penalties include a $750 to $2,000 fine, 18- to 24-month license revocation, and a mandatory minimum sentence of 10 consecutive days (3 days in county corrections, 7 days at the state Multiple Offender Program).

Second Offense (within 2-10 years): Fine of $750 to $2,000; 3-year license revocation; mandatory minimum of 10 consecutive days (3 days county corrections, 7 days Multiple Offender Program). If the second offense occurs within 2 years of the first, the mandatory jail sentence increases to 30 days.

Third and Subsequent Offenses: A third or subsequent DWI is a class A misdemeanor or felony depending on timing and circumstances, with escalating mandatory minimum sentences, longer license revocations, and potential requirement to install an ignition interlock device.

Implied Consent (RSA 265-A:4): Any person operating a motor vehicle in New Hampshire is deemed to have consented to chemical testing. Refusal results in a 180-day license suspension for a first refusal and a 2-year suspension for subsequent refusals.

Drug-Impaired Driving: DWI involving controlled drugs carries the same penalties as alcohol-related DWI. There is no per se limit for drug concentration — impairment is established through officer testimony, Drug Recognition Expert evaluations, and toxicology reports.

New Hampshire has implemented broad naloxone access measures to combat opioid overdose deaths. Under RSA 318-B:15, IV, pharmacists and organizations are authorized to dispense or distribute opioid antagonists (naloxone or nalmefene) pursuant to a prescription or standing order.

Standing Order: The State Chief Medical Officer has issued a statewide standing order authorizing any licensed New Hampshire pharmacist to dispense naloxone or nalmefene without an individual prescription to any person at risk of an opioid overdose, or to any family member, friend, or other person in a position to assist someone at risk of overdose.

Available Forms: Under the standing order, pharmacists may dispense naloxone in multiple forms, including: prefilled nasal spray (Narcan 4mg or Kloxxado 8mg), prefilled Luer-lock syringes with mucosal atomizing devices (1mg/mL), and nalmefene nasal spray for persons age 12 and older.

Overdose Response Counseling: Pharmacists are required to provide opioid overdose response counseling at the time of dispensing, including information on recognizing overdose symptoms, calling 911, and proper administration techniques.

Immunity Provisions: Pharmacists and other persons who dispense or administer naloxone in good faith and with reasonable care are immune from civil and criminal liability under New Hampshire law. This applies to both professional dispensers and laypersons who administer naloxone in an emergency.

Community Distribution: New Hampshire also supports naloxone distribution through community-based organizations, harm reduction programs, and emergency medical services to ensure broad availability of the life-saving medication.

New Hampshire operates felony drug court programs through the state judicial branch's Treatment Courts system, providing treatment-based alternatives to traditional incarceration for individuals with substance use disorders who are involved in the criminal justice system.

Availability: Drug court programs are available in Belknap, Carroll, Cheshire, Coos, Grafton, Hillsborough (North and South), Merrimack, Rockingham, and Strafford Counties, covering nearly every county in the state.

Program Structure: New Hampshire drug courts operate as 12-month alternative sentencing programs divided into three phases, followed by one year of probation. Under the supervision of a dedicated drug court judge and parole officer, participants receive community-based treatment while living and working in the community. Programs include frequent court appearances, random drug and alcohol testing, intensive supervision, and comprehensive substance abuse treatment including individual and group counseling.

Eligibility: Drug court programs generally serve adult offenders charged with felony-level drug offenses whose criminal behavior is substantially linked to substance use disorders. Violent offenders and major drug traffickers are typically excluded.

Outcomes: Drug court graduates in New Hampshire have demonstrated significantly lower recidivism rates — approximately 22% for graduates in Grafton and Strafford counties, compared to approximately 40% for the general prison population statewide and nearly 60% nationally.

Additional Treatment Courts: Beyond drug courts, New Hampshire also operates mental health courts, veterans treatment courts, and DWI courts within its treatment court framework to address the specific needs of different populations involved in the criminal justice system.

New Hampshire imposes mandatory minimum sentences for certain categories of drug offenses, primarily focused on school zone violations and distribution offenses rather than simple possession.

Drug-Free School Zone (RSA 318-B:26, III): Any person who manufactures, sells, dispenses, or possesses with intent to distribute a controlled substance within 1,000 feet of school property or on a school bus is subject to a mandatory minimum term of imprisonment of not less than 1 year. Penalties may be doubled from the standard sentencing range, and the court may impose a fine of up to $500,000 or 5 times the street value of the drug, whichever is greater.

Distribution with Death Resulting (RSA 318-B:26, IX): A person who manufactures, sells, or dispenses methamphetamine, LSD, PCP, or any Schedule I or II substance, and a death results from the use of that substance, is subject to strict liability and may be sentenced to life imprisonment. The decedent's contributory conduct is not a defense.

Repeat Offender Enhancements: Under RSA 318-B:27, a person convicted of a drug offense who has one or more prior drug convictions faces enhanced penalties. For distribution offenses, repeat offenders face up to life imprisonment and a $500,000 fine. For possession offenses, the charge elevates from a class B felony to a class A felony.

Minimum Fines: All drug offense convictions carry a mandatory minimum fine of $350 for a first offense and $500 for a subsequent offense under RSA 318-B:26.

Pending Legislation (2025): Senate Bill 14, passed by the NH House in June 2025, proposes new mandatory minimums specifically for fentanyl possession — 3.5 years for 5 grams or more and 7 years for 28 grams or more. The bill also reduces penalties for psilocybin mushrooms. This legislation may alter the mandatory minimum landscape if enacted.

New Hampshire provides several pathways for diverting drug offenders from incarceration into treatment programs:

Drug Court Programs: The state's treatment court system operates drug courts in nearly every county (Belknap, Carroll, Cheshire, Coos, Grafton, Hillsborough North and South, Merrimack, Rockingham, and Strafford). These 12-month, three-phase programs combine supervised treatment with court accountability. Successful completion can result in reduced charges or modified sentences.

Conditional Discharge (RSA 318-B:28): For first-time offenders convicted of simple possession, courts may place the individual on conditional discharge without entering a conviction, provided the person completes a drug treatment program or other conditions set by the court. Upon successful completion, the charge may be dismissed.

Suspended Sentences and Probation: New Hampshire courts have broad discretion to suspend sentences and impose probation with conditions including mandatory substance abuse treatment, counseling, and regular drug testing for drug-related offenses.

Substance Abuse Assessment: Under the marijuana decriminalization provision (RSA 318-B:2-c), courts may waive fines for marijuana violations upon proof that the person has completed a substance abuse assessment by a licensed drug and alcohol counselor within 60 days of conviction.

Doorway (NH Rapid Response Access Points): New Hampshire operates Doorway programs — formerly known as SOR-funded hub-and-spoke treatment centers — that provide rapid access to substance use disorder treatment including medication-assisted treatment (MAT), counseling, and recovery support services. Courts may refer individuals to these programs as part of sentencing alternatives.

Veterans Treatment Courts: Veterans whose criminal behavior is linked to service-related substance use disorders can be directed to specialized veterans treatment courts that offer tailored treatment, mentoring, and case management in lieu of incarceration.

New Hampshire has enacted and considered several significant changes to its drug laws between 2023 and 2025:

2023 — Fentanyl and Xylazine Test Strip Legalization: New Hampshire legalized fentanyl test strips and xylazine test strips, removing them from the definition of drug paraphernalia. This allows individuals to test substances for the presence of fentanyl and xylazine without fear of criminal prosecution.

2024 — Expanded Drug Checking Legislation: The New Hampshire House passed a bill to enable comprehensive drug checking beyond just fentanyl and xylazine test strips, providing that a person possessing less than 10 milligrams of a controlled substance for the purpose of drug checking would not be subject to prosecution. This reflects concerns about new adulterants and contaminants entering the drug supply.

2024 — Senate Fentanyl Bills: The Senate passed three major fentanyl-related bills: SB 316 (mandatory minimum for transporting fentanyl into NH with intent to distribute), SB 414 (10-year mandatory minimum for distribution with death resulting), and SB 415 (mandatory minimums for fentanyl possession: 3.5 years for 5+ grams, 7 years for 28+ grams). The House sent some of these to interim study.

2025 — Senate Bill 14 (Fentanyl Mandatory Minimums): In June 2025, the NH House passed SB 14 by a vote of 214-167, which creates mandatory minimums for fentanyl possession and reduces the penalty for possession of psilocybin mushrooms. As of mid-2025, the bill's final status is pending.

2025 — Federal HALT Fentanyl Act: The federal HALT Fentanyl Act, supported by the New Hampshire congressional delegation, permanently scheduled fentanyl analogues at the federal level, complementing state-level enforcement efforts.

Ongoing — Recreational Marijuana Debate: Multiple bills to legalize recreational marijuana have been introduced in the NH legislature over recent sessions but have not passed. New Hampshire remains the only New England state without legalized recreational cannabis.
