Penal Law §§ 220.03 through 220.21 grade criminal possession of a controlled substance from a Class A misdemeanor (seventh-degree possession) up to a Class A-I felony (first-degree possession). Weight, drug identity, and intent to sell drive the grade. A possession charge that looks minor on the desk appearance ticket can carry years in state prison if the drug is heroin, fentanyl, or methamphetamine and the weight reaches the felony threshold.
Possession is a knowing exercise of dominion and control. The prosecution must prove that the client knew the substance was where it was found and knew (or is deemed by law to know) what it was. In practice, that gives the defense two distinct attacks: knowledge of presence and knowledge of identity.
Knowledge of presence is the cleaner argument in shared-space cases. A client who lets a friend stay in the apartment, who borrows the car, or who rides as a passenger does not automatically possess what the friend or driver hid. The People have to put more on the table than location — admissions, fingerprints, DNA, surveillance, or proximity to personal effects. Without that connection, a trial-order-of-dismissal motion under CPL § 290.10 has teeth.
Most contested possession cases are constructive-possession cases. The drugs are found in a car, an apartment, a stash spot, or a bag that several people had access to. The People rely on dominion and control over the place, plus circumstantial proof of knowledge.
PL § 220.25 gives the prosecution two statutory presumptions to bridge the gap.
Both presumptions are permissive. The jury may infer possession, not must. The court must instruct the jury that they may reject the presumption, and the defense gets to argue alternative explanations — the hitchhiker, the rideshare, the borrowed apartment.
The drugs only matter if they are admissible. Suppression under CPL § 710 is the first line of defense in nearly every possession case. The areas that get the most traction:
CPL Article 245 obligates the People to turn over their case file early and completely. In a possession case the defense should be reading:
An incomplete or boilerplate certificate of compliance is a CPL § 30.30 issue. We do not let it slide.
The People prove drug identity and weight through a lab report and an analyst. Under Crawford v. Washington and Bullcoming v. New Mexico, a substitute analyst testifying to another chemist's report violates the Confrontation Clause. We require the actual analyst at the hearing and at trial.
Weight is aggregate. The lab weighs the entire mixture or substance, including cutting agents. That is statutory — PL § 220.00 defines "narcotic preparation" and the felony tiers run on aggregate weight, not pure-drug weight. Two consequences follow. First, packaging, moisture, and tare matter; we cross on each. Second, where the charged weight sits within a gram or two of a threshold, an independent reweighing can drop the case a felony class or out of felony territory entirely.
Third-degree possession under PL § 220.16 jumps to a Class B felony when the People allege intent to sell, regardless of weight on most narcotics. Intent is proved circumstantially — packaging in many small bags, pre-recorded buy money, scales, ledgers, multiple phones, and statements. The defense answers with personal-use evidence, addiction context, and a careful cross of the officer who claims to recognize "street-level packaging."
The agency defense is available where the defendant acted solely as the buyer's agent in obtaining drugs from a seller. It is a complete defense to sale charges if the jury believes it. The defense fits some cases (the friend who fetches drugs for another addict) and not others (the runner working off the seller's stash). We evaluate it carefully because the wrong record can sink it.
Eligible felony defendants can apply for judicial diversion under CPL Article 216. The Drug Treatment Court alternative trades a guilty plea for completion of a treatment program, with dismissal or reduction on completion. We evaluate every drug case for diversion eligibility from day one.
Class B, C, D, and E felony possession and sale offenses are presumptively eligible if the defendant has a substance-use history connected to the offense and no disqualifying prior conviction. A clinical evaluation, the alcohol and substance abuse subdivision (ASAS) screening, and a treatment plan accepted by the court are the moving parts. Successful completion can result in dismissal, reduction to a misdemeanor, or a sentence of probation — depending on what the plea agreement specified.
A controlled-substance conviction carries consequences far beyond the sentence. Non-citizens face deportation under 8 U.S.C. § 1227(a)(2)(B); trafficking-related convictions can be aggravated felonies under 8 U.S.C. § 1101(a)(43)(B). Public housing eligibility, federal student aid, professional licensing, firearms rights, and employment in regulated industries all turn on the offense of conviction. Plea structure — whether the disposition is a misdemeanor under PL § 220.03, a deferred plea, or a felony with a youthful-offender adjudication — can be the difference between a manageable record and a life-altering one.
For clients who already have an old drug conviction, CPL § 160.59 permits sealing of up to two eligible convictions (no more than one felony) after a ten-year waiting period, subject to category exclusions. We evaluate sealing eligibility as part of any consultation.
If you have been arrested or are about to be questioned, say nothing about the drugs, the place where they were found, or anyone else. Do not consent to a search. Do not try to talk your way out of it at the precinct. Ask for a lawyer and stay quiet on jail calls — every one of them is recorded. The single most useful step in the first 48 hours is putting counsel between you and the investigators.
