Drug laws in New York City come from New York State Penal Law, and they split sharply along one line: cannabis is legal for adults 21 and older within set limits, while almost every other controlled substance carries a misdemeanor or felony charge even in small amounts. Federal law has not followed the state on cannabis, which creates consequences for air travelers and non-citizens that catch people off guard.
What Adults Can Legally Do With Cannabis
If you are 21 or older, you can possess up to three ounces of cannabis flower or 24 grams of concentrated cannabis (edibles, oils, and similar products) outside the home.1New York State Unified Court System. Cannabis (Marihuana) Basics Under New York State Law There is no penalty for carrying those amounts in public. Go over three ounces and the penalties start as a violation and climb to felony charges at higher weights.
You can smoke or vape cannabis wherever tobacco smoking is allowed. The exceptions matter: motor vehicles, workplaces, restaurants and their patios, schools, federal property including public housing, and most public parks and beaches are off-limits.2New York State Office of Cannabis Management. Know Your Rights With Cannabis Breaking those restrictions carries a civil penalty of up to $25 or up to 20 hours of community service.3New York State Unified Court System. New York Penal Law Article 222 Cannabis
Growing at Home
Adults 21 and older can cultivate cannabis at home: up to three mature and three immature plants per person, with a household cap of 12 plants (six mature, six immature) if more than one qualifying adult lives there. You can store up to five pounds of harvested flower from your plants inside your residence.4New York State Office of Cannabis Management. Medical and Adult-Use Home Cultivation of Cannabis FAQ
Plants must be kept somewhere no one under 21 can reach them. Selling or trading what you grow is illegal in any amount. Landlords may adopt smoke-free policies and may restrict cultivation, so read your lease before you plant.
Why Federal Law Still Matters for Cannabis
Cannabis is still a Schedule I controlled substance under the federal Controlled Substances Act. An executive order has directed the Attorney General to complete the process of rescheduling it to Schedule III, but as of early 2026 the rulemaking is pending and nothing has changed.5The White House. Increasing Medical Marijuana and Cannabidiol Research Even if rescheduling goes through, it would not decriminalize cannabis nationwide or override state law.
The practical trap is air travel. Flying with cannabis is illegal under federal law, even on a flight between two states where cannabis is legal. TSA officers do not actively hunt for drugs, but they are required to report suspected violations to law enforcement if they find cannabis during screening.6Transportation Security Administration. Medical Marijuana Once you clear the checkpoint, you are on federal property.
Possession of Other Controlled Substances
Everything other than legal cannabis is prosecuted under New York Penal Law Article 220.7New York State Senate. New York Penal Law Article 220 Controlled Substances Offenses Penalties scale with the substance, the quantity, and whether prosecutors can show intent to sell.
The Misdemeanor Baseline
The entry-level charge is criminal possession in the seventh degree, a Class A misdemeanor carrying up to one year in jail and a fine of up to $1,000.8New York State Senate. New York Penal Law 220.03 Criminal Possession of a Controlled Substance in the Seventh Degree This is the typical charge for a small personal-use quantity of a drug like cocaine or heroin.
Two carve-outs are important. A residual amount of a controlled substance on a syringe or needle does not violate this section. And if possession is discovered because you or someone else called for emergency medical help during an overdose, that discovery cannot be prosecuted under this charge.8New York State Senate. New York Penal Law 220.03 Criminal Possession of a Controlled Substance in the Seventh Degree The Good Samaritan protection exists so people call 911 without fearing arrest.
When Possession Becomes a Felony
Possession jumps to a felony once specific weight thresholds are crossed or when there is evidence of intent to sell. The tiers include:
- Fifth degree, a Class D felony, applies when there is intent to sell any controlled substance, or when quantities such as 500 milligrams or more of cocaine or a half-ounce or more of a narcotic preparation are involved. A first conviction carries one to two and a half years in prison.9New York State Senate. New York Penal Law 220.06 Criminal Possession of a Controlled Substance in the Fifth Degree10New York State Senate. New York Penal Law 70.70 Sentence of Imprisonment for Felony Drug Offender
- Fourth degree, a Class C felony, covers one-eighth ounce or more of a narcotic drug or one gram or more of a stimulant, with a range of one to five and a half years.11New York State Senate. New York Penal Law 220.09 Criminal Possession of a Controlled Substance in the Fourth Degree10New York State Senate. New York Penal Law 70.70 Sentence of Imprisonment for Felony Drug Offender
- First degree, a Class A-I felony, applies at eight ounces or more of a narcotic drug and carries eight to twenty years for a first conviction.12New York State Senate. New York Penal Law 220.21 Criminal Possession of a Controlled Substance in the First Degree13Justia Law. New York Penal Law 70.71 Sentence of Imprisonment for a Class A Felony Drug Offender
Prior felony drug convictions lengthen sentences substantially at every tier.
Selling Drugs Is Always a Felony
Every drug sale offense in New York is a felony. There is no misdemeanor-level sale charge.
- Fifth degree, a Class D felony, is the entry-level sale charge for any knowing and unlawful sale, with one to two and a half years for a first conviction.14New York State Senate. New York Penal Law 220.31 Criminal Sale of a Controlled Substance in the Fifth Degree10New York State Senate. New York Penal Law 70.70 Sentence of Imprisonment for Felony Drug Offender
- Fourth degree, a Class C felony, covers selling a narcotic preparation, methadone, or any controlled substance on school grounds or a school bus, with one to five and a half years.15New York State Senate. New York Penal Law 220.34 Criminal Sale of a Controlled Substance in the Fourth Degree10New York State Senate. New York Penal Law 70.70 Sentence of Imprisonment for Felony Drug Offender
- Third degree, a Class B felony, applies to selling any narcotic drug, selling a gram or more of a stimulant, or selling a narcotic preparation to someone under 21, with a first conviction carrying one to nine years.16New York State Senate. New York Penal Law 220.39 Criminal Sale of a Controlled Substance in the Third Degree10New York State Senate. New York Penal Law 70.70 Sentence of Imprisonment for Felony Drug Offender
- First degree, a Class A-I felony, applies at two ounces or more of a narcotic drug and carries eight to twenty years for a first conviction.17New York State Senate. New York Penal Law 220.43 Criminal Sale of a Controlled Substance in the First Degree13Justia Law. New York Penal Law 70.71 Sentence of Imprisonment for a Class A Felony Drug Offender
The school-grounds enhancement is worth watching. A sale within school property or on a school bus bumps the charge from fifth degree to fourth degree, and if the school’s presence is marked with conspicuous signage, you are presumed to have known you were in the zone.15New York State Senate. New York Penal Law 220.34 Criminal Sale of a Controlled Substance in the Fourth Degree
Driving While Impaired by Drugs
DWAI/Drugs falls under Vehicle and Traffic Law Section 1192(4). There is no numeric threshold like a blood-alcohol limit; the prosecution just has to show the drug impaired your ability to drive.18New York State Senate. New York Vehicle and Traffic Law 1192 Operating a Motor Vehicle While Under the Influence of Alcohol or Drugs The substance can be illegal or a legally prescribed medication; it does not matter.
A first conviction is a misdemeanor with a fine of $500 to $1,000, up to one year in jail, and a mandatory six-month license revocation. A second conviction within ten years is a Class E felony with a $1,000 to $5,000 fine range and a mandatory one-year revocation.19New York State Senate. New York Vehicle and Traffic Law 1193 Sanctions Cannabis legalization did not change this. If an officer concludes cannabis impaired your driving, the charges are the same ones a person impaired by opioids would face.
Immigration Consequences for Non-Citizens
Federal immigration law does not recognize New York’s cannabis legalization. A non-citizen convicted of any controlled substance offense after admission to the United States is deportable, with one narrow exception: a single offense involving personal possession of 30 grams or less of marijuana.20Office of the Law Revision Counsel. 8 USC 1227 Deportable Aliens That exception does not cover sale, distribution, or possession of any other drug. A non-citizen who has been a drug abuser or addict at any time after admission is also deportable, with no conviction required.
The risk is not confined to criminal court. Admitting marijuana use to an immigration officer during a green card or citizenship application can delay or derail the process, and lying about it carries its own serious consequences. For any interaction with federal authorities, border crossings, or immigration applications, non-citizens living in New York should treat cannabis as if it were still prohibited.
Alternatives to Jail: Diversion and Treatment Courts
New York offers routes out of a conviction for defendants whose offenses are driven by substance use, and many people never ask about them.
Judicial Diversion
Under Criminal Procedure Law Article 216, eligible felony defendants can request a court-ordered substance use evaluation and, if approved, be diverted into treatment instead of going to trial. The court looks at whether the defendant has a history of substance use, whether that use contributed to the criminal conduct, and whether treatment could address it.21New York State Senate. New York Criminal Procedure Law 216.05 Judicial Diversion Program
Successful completion can lead to withdrawal of a guilty plea and dismissal of the indictment. In other cases the court may allow a plea to a reduced misdemeanor. The program is available any time after arraignment and before trial, and where a guilty plea would trigger severe collateral consequences such as deportation, the court can waive the plea requirement based on exceptional circumstances.21New York State Senate. New York Criminal Procedure Law 216.05 Judicial Diversion Program
Drug Treatment Courts
NYC runs drug treatment court programs for felony and misdemeanor defendants whose charges tie to drug addiction. Completion can bring dismissal, reduction of charges, or a lighter sentence.22New York State Unified Court System. Drug Treatment Courts Some boroughs also operate opioid intervention courts, which divert misdemeanor defendants into treatment services and typically dismiss charges on completion.
The Surcharges Nobody Mentions
Every criminal conviction in New York carries mandatory surcharges the court cannot waive. A felony conviction adds a $300 mandatory surcharge plus a $25 crime victim assistance fee. A misdemeanor adds a $175 surcharge plus the same $25 fee. These sit on top of any fine the judge imposes, and defendants who planned only for the fine are often caught short.
