Criminal Possession of a Controlled Substance in the Third Degree, often shortened to CPCS 3rd in New York, is a Class B felony under Penal Law 220.16. It applies when you knowingly and unlawfully possess a narcotic with intent to sell, or when you possess certain controlled substances above specific weight thresholds even without any evidence of a sale. A first conviction carries one to nine years in state prison, a fine of up to $30,000, and a mandatory period of post-release supervision.
What Triggers the Charge
Every case under Penal Law 220.16 starts with two baseline elements: that you knowingly possessed a controlled substance, and that the possession was unlawful. “Knowingly” means you were aware the substance was on you or under your control. Drugs slipped into your bag by someone else do not satisfy this element.
Beyond those baselines, the statute lists more than a dozen scenarios that bump simple possession up to the third degree. They fall into two broad paths.
The first is intent to sell. Possessing any amount of a narcotic drug with intent to sell qualifies, no minimum weight required. Prosecutors rarely need to catch a hand-to-hand transaction. They build intent from circumstantial evidence: individually packaged quantities, digital scales, large amounts of cash, text messages discussing sales, or an arrest in a known drug-market location.
The second path skips intent entirely and relies on weight. If the drugs exceed the statutory thresholds, the charge applies even if everything about the facts suggests personal use. The intent-to-sell subsections and the weight-only subsections stand independently, and prosecutors pick whichever one fits the evidence they have.
Possession itself does not require drugs to be in your pocket. New York recognizes constructive possession, which means you can be charged when drugs are found in a space you control, such as your car, apartment, or workplace, even if they were not physically on your body. The prosecution has to show you knew the drugs were there and had the ability to exercise control over them. In shared apartments, this question of knowledge and control often becomes the heart of the case.
Weight Thresholds by Substance
Narcotics
Heroin, cocaine, fentanyl, and oxycodone reach the third degree through two routes. Any amount with intent to sell is enough. Without intent, the trigger is an aggregate weight of one-half ounce or more. Aggregate weight includes the full mixture, cutting agents and all, not just the pure drug content.1New York State Senate. New York Penal Law 220.16 – Criminal Possession of a Controlled Substance in the Third Degree
Stimulants and Methamphetamine
Stimulants work in tiers. One gram or more with intent to sell qualifies. Without intent, the threshold is five grams or more. Methamphetamine has its own subsection: an aggregate weight of one-eighth ounce or more with intent to sell.1New York State Senate. New York Penal Law 220.16 – Criminal Possession of a Controlled Substance in the Third Degree
Hallucinogens and LSD
These require both intent to sell and a minimum weight. LSD triggers at one milligram or more with intent to sell. Other hallucinogens require twenty-five milligrams or more with intent to sell, and hallucinogenic substances require one gram or more with intent to sell. A separate subsection covers any of these substances with intent to sell at any weight if you have a prior drug conviction under Article 220.1New York State Senate.

Penalties for a First Offense
CPCS 3rd degree is a Class B felony, and New York uses determinate sentencing for drug felonies. With no prior felony convictions, the judge must impose a fixed prison term between one and nine years.2New York State Senate. New York Penal Code 70.70 – Sentence of Imprisonment for Felony Drug Offender Other Than a Class A Felony A four-year sentence means four years, minus any good-time credit, followed by supervision.
The court may add a fine of up to $30,000. When setting the amount, the judge weighs any profit from the offense, proportionality, impact on victims, and your ability to pay.3New York State Senate. New York Penal Code 80.00 – Fine for Felony Every felony conviction also carries an automatic $300 mandatory surcharge and a $25 crime victim assistance fee imposed at sentencing.4New York State Senate. New York Penal Code 60.35 – Mandatory Surcharge, Sex Offender Registration Fee, DNA Databank Fee, Supplemental Sex Offender Victim Fee and Crime Victim Assistance Fee
After the prison term, New York requires one to two years of post-release supervision for Class B drug felonies.5New York State Senate. New York Penal Code 70.45 – Determinate Sentence; Post-Release Supervision You report to a parole officer within 24 hours of release and need approval for where you live, submit to home and property searches, and get permission before leaving the state. Violating the conditions can send you back to prison.6Department of Corrections and Community Supervision. Community Supervision
How a Prior Record Changes the Numbers
Sentencing escalates sharply if you have a prior felony. New York uses a ten-year lookback period, and any time you spent incarcerated during that window does not count against the clock. Five years in prison effectively stretches the lookback to fifteen calendar years.7New York State Senate. New York Penal Code 70.06 – Sentence of Imprisonment for Second Felony Offender
If your prior felony was non-violent, you are classified as a second felony drug offender, and the Class B sentencing range shifts to two to twelve years. The two-year floor is mandatory. If the prior was a violent felony, the range jumps to six to fifteen years, with the six-year minimum leaving essentially no judicial discretion at the low end.2New York State Senate. New York Penal Code 70.70 – Sentence of Imprisonment for Felony Drug Offender Other Than a Class A Felony
The harshest designation is persistent felony offender, which can apply when you have two or more qualifying prior felony convictions where you were actually imprisoned. If the judge makes specific findings that your history and conduct warrant extended incarceration and lifetime supervision, the court can impose the sentence authorized for a Class A-I felony, which includes the possibility of life in prison.8New York State Senate. New York Penal Code 70.10 – Sentence of Imprisonment for Persistent Felony Offender
Judicial Diversion Can Replace Prison with Treatment
For many people charged with CPCS 3rd degree, the most important option in the entire case is judicial diversion under Criminal Procedure Law 216.05. The program lets eligible defendants enter substance use treatment instead of going to prison, and completing it can end the case without a felony on your record.
At any point after arraignment but before trial, you can ask the court to order a substance use evaluation. The court can grant diversion if it finds that you have a history of substance use, that the use contributed to your criminal behavior, that treatment could effectively address the problem, and that incarceration is not necessary to protect the public.9New York State Senate. New York Criminal Procedure Law 216.05 – Judicial Diversion Program
You will usually need to enter a guilty plea before starting the program, although the court can waive that requirement in exceptional circumstances or with the prosecutor’s consent. If you complete treatment and satisfy all conditions, the court may let you withdraw the plea and dismiss the indictment entirely. In other cases, the court may allow a plea down to a misdemeanor.9New York State Senate. New York Criminal Procedure Law 216.05 – Judicial Diversion Program
Diversion is not open to everyone. The court weighs public safety heavily, and certain violent criminal histories can disqualify a defendant. For a straightforward CPCS 3rd degree case where substance use genuinely drove the behavior, this program exists precisely to provide an exit. Ask about eligibility as early in the case as possible.
Suppressing the Evidence
Drug possession cases live or die on the physical evidence. If the drugs are suppressed, the prosecution usually has no case left. The Fourth Amendment requires a warrant to search your home, and warrantless searches are presumptively unreasonable, but officers rely on several recognized exceptions: consent, search incident to lawful arrest, plain view, exigent circumstances, and the automobile exception during a valid traffic stop with probable cause.10United States Courts. What Does the Fourth Amendment Mean?
When police overstep, the exclusionary rule bars the prosecution from using the evidence at trial, and it reaches “fruit of the poisonous tree,” meaning anything discovered because of the initial illegal search is also excluded. Exceptions exist for good-faith reliance on an invalid warrant, inevitable discovery through lawful means, and independent sources unrelated to the violation.11Legal Information Institute. Exclusionary Rule If the stop was unjustified, the search exceeded the scope of consent, or officers entered a home without a recognized exception, a successful suppression motion often ends the prosecution.
Consequences Outside the Criminal Case
Two federal consequences hit CPCS 3rd convictions especially hard.
For non-citizens, federal immigration law makes any person deportable who has been convicted of violating any law relating to a controlled substance. The one narrow exception covers a single offense involving personal possession of 30 grams or less of marijuana, which a CPCS 3rd case will never fit. Deportation is virtually certain, and the conviction creates a permanent bar to most forms of immigration relief.12Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
Federal law also permanently prohibits anyone convicted of a crime punishable by more than one year in prison from possessing any firearm or ammunition. Because CPCS 3rd degree carries up to nine years, any conviction triggers that lifetime ban, including constructive possession such as a firearm stored at home. A violation is a separate federal offense carrying up to ten years in prison.13Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
Other collateral consequences include difficulty finding employment, ineligibility for certain professional licenses, loss of public housing eligibility, and restrictions on federal student financial aid. None of these appear in the sentencing statute, but they shape daily life long after the criminal case closes.
