Is Drug Possession a Felony in California? Health and Safety Code 11350 and 11377 Explained
The short answer: for most people, simple possession of a controlled substance for personal use is a misdemeanor in California, not a felony. Since Proposition 47 passed in 2014, possession of drugs such as heroin, cocaine, or prescription opiates under Health and Safety Code section 11350 and possession of methamphetamine and similar drugs under Health and Safety Code section 11377 are misdemeanors punishable by up to one year in county jail. The charge becomes a felony or wobbler only for people with certain serious prior convictions or sex offender registration, and possession for sale, transportation, and sale remain felonies. Proposition 36, approved by voters in November 2024, added a new felony-level path for people with two or more prior drug convictions. This guide explains each element the prosecutor must prove, the defenses that work, and the diversion programs that get these cases dismissed in Victorville, San Bernardino, Fontana, Riverside, Moreno Valley, Pomona, and Lancaster.
What the Prosecutor Must Prove for Simple Possession
Five elements, each beyond a reasonable doubt. To convict you of possession under Health and Safety Code section 11350 or Health and Safety Code section 11377, the prosecutor must prove that (1) you possessed a controlled substance, (2) you knew of its presence, (3) you knew of its nature as a controlled substance, (4) the substance was in fact a controlled substance listed in the statute, and (5) the amount was a usable quantity. The jury instruction for this offense is CALCRIM 2304. Each element is a separate opportunity for the defense.
Possession can be actual or constructive. Actual possession means the drug was on your person or in something you were holding. Constructive possession means you had the right to control the drug, alone or with someone else, even if it was somewhere else, such as a glove box, a bedroom dresser, or a shared backpack. Two people can possess the same item. But mere presence near drugs, or knowing that someone else has drugs, is not possession. The California Supreme Court explained in People v. Williams (1971) 5 Cal.3d 211 that proximity and access alone do not establish the dominion and control that possession requires.
Knowledge has two parts. The prosecutor must show you knew the item was there and that you knew it was a controlled substance. You do not have to know the exact chemical name, but you must know it is a drug. Knowledge is usually proven circumstantially, by where the item was found, statements you made, prior familiarity, or attempts to hide it. In People v. Palaschak (1995) 9 Cal.4th 1236, the Supreme Court confirmed that knowledge of the character of the substance is an element the jury must find. A car passenger who did not know about a baggie under the driver's seat has a knowledge defense, and so does a person holding a friend's bag.
Usable quantity matters. Trace residue is not enough. The rule traces to People v. Leal (1966) 64 Cal.2d 504, which held that possession of useless traces or residue does not violate the statute. The Supreme Court refined the rule in People v. Rubacalba (1993) 6 Cal.4th 62, holding that the prosecution need not prove the amount was enough to produce a narcotic effect, only that it was usable for consumption rather than a mere trace. Residue inside a pipe is the classic dispute, and it is why the laboratory weight and the criminalist's testimony matter.
Which drug and which statute. Health and Safety Code section 11350 covers the substances listed in it, which include heroin, cocaine, and many prescription opiates and other Schedule I and II drugs possessed without a valid prescription. Health and Safety Code section 11377 covers methamphetamine and a range of other stimulants, depressants, and hallucinogens. Cannabis is governed separately by Health and Safety Code section 11357 after Proposition 64, and paraphernalia is a separate misdemeanor under Health and Safety Code section 11364. The lab report, not the officer's field test, establishes what the substance was.
When Drug Possession Is a Felony in California
The Proposition 47 exceptions. Both statutes make simple possession a misdemeanor unless the defendant has a prior conviction for an offense listed in Penal Code section 667, subdivision (e)(2)(C)(iv), the so-called super strikes such as murder and certain sex offenses, or is required to register as a sex offender under Penal Code section 290. For those defendants, possession is a wobbler that the prosecutor can file as a felony punishable in county jail under Penal Code section 1170, subdivision (h).
Proposition 36 of 2024. Voters approved a new measure in November 2024 that created a treatment-mandated felony for people charged with possession who have two or more prior convictions for specified drug offenses. Under that framework, an eligible defendant can choose treatment and earn a dismissal, while a defendant who declines or fails treatment faces felony consequences. The provisions are new, the local implementation varies by county, and the details of who qualifies and what treatment satisfies the statute should be confirmed against the current text of the Health and Safety Code and your county's practice. If you have prior drug convictions, ask your lawyer specifically about this before your first court date.
Possession for sale is different. Health and Safety Code section 11351 and Health and Safety Code section 11378 make possession with intent to sell a felony, and Health and Safety Code section 11352 and Health and Safety Code section 11379 cover transportation and sale. Prosecutors in Riverside County and San Bernardino County frequently charge sales based on quantity, packaging, scales, cash, and text messages rather than an actual sale. Reducing a sales charge to simple possession is one of the most common and most valuable outcomes in drug cases, because it moves the case from felony to misdemeanor and opens the door to diversion. Our guide on whether police can use your text messages explains how phone evidence is used and challenged in these cases.
Being under the influence. Health and Safety Code section 11550 separately makes it a misdemeanor to be under the influence of specified controlled substances. It is often charged alongside possession after a traffic stop in Victorville, Hesperia, or Fontana and depends on the officer's observations and a blood or urine test.
Common Defenses to Drug Possession Charges
Illegal search or seizure. Most possession cases start with a traffic stop, a pat-down, or a search of a car or home. If the stop lacked reasonable suspicion, the search exceeded its lawful scope, or consent was not voluntary, the drugs can be suppressed under Penal Code section 1538.5 and the case usually ends. Arizona v. Gant (2009) 556 U.S. 332 limits vehicle searches after an arrest, Riley v. California (2014) 573 U.S. 373 requires a warrant to search a phone, and Terry v. Ohio (1968) 392 U.S. 1 limits pat-downs to weapons. See our guides to car searches in California and 1538.5 motions.
Lack of knowledge. The drugs were in a borrowed car, a shared apartment, a jacket someone else wore, or a bag you were carrying for someone else. The prosecutor must prove you knew the drugs were there and knew what they were. Without a statement from you, that proof is often thin. This is the single most important reason not to answer questions at the scene; our guide on your rights when questioned by police explains why.
No possession, only presence. Three people in a car and a baggie on the floorboard is not three possession cases. The prosecutor has to tie the drugs to you specifically through location, fingerprints, statements, or other evidence. Under People v. Williams (1971) 5 Cal.3d 211, presence and access are not enough.
Not a usable amount. Residue in a pipe or a baggie with only trace powder may not satisfy the usable quantity requirement under People v. Leal (1966) 64 Cal.2d 504 and People v. Rubacalba (1993) 6 Cal.4th 62. Demand the lab report and the net weight.
Valid prescription. Both statutes exempt possession under a written prescription from a licensed practitioner. Pharmacy records and a physician's letter can end a case involving pills.
Lab and chain of custody problems. The field test is presumptive. The case depends on a crime laboratory analysis, and the criminalist must be available for cross-examination. Gaps in the chain of custody, delayed testing, or a lab report that does not match the seized item are all grounds to challenge the fourth element.
Momentary possession for disposal. California recognizes a narrow defense when a person possessed a drug only momentarily and solely to dispose of it or prevent someone else from using it, without intent to keep it. The defense is fact-specific and rarely succeeds without corroboration, but it exists.
Diversion and Other Ways to Avoid a Conviction
Pretrial drug diversion under Penal Code 1000. Penal Code section 1000 allows eligible defendants charged with specified possession offenses, including Health and Safety Code section 11350 and Health and Safety Code section 11377, to enter a treatment program before any plea. Since the 2018 amendments, the program is true pretrial diversion, meaning you do not plead guilty first. If you complete the program, the charge is dismissed and the arrest is deemed not to have occurred for most purposes. Eligibility generally requires no prior conviction for a controlled substance offense other than possession-type offenses within the last five years, no violence in the current case, and no prior diversion within five years; confirm the current eligibility list against the statute.
Misdemeanor diversion under Penal Code 1001.95. Penal Code section 1001.95 lets a judge divert most misdemeanors for up to 24 months, over the prosecutor's objection, with dismissal on completion. Drug possession is not on the excluded list. This is the tool of choice when a client does not qualify for Penal Code section 1000 because of a prior. Our companion guide explains how misdemeanor diversion works.
Mental health diversion. Penal Code section 1001.36 provides up to two years of diversion for a defendant with a qualifying mental health diagnosis that was a significant factor in the offense. Substance use disorder alone is not a qualifying diagnosis under the statute, but co-occurring conditions such as depression, PTSD, or bipolar disorder often are, and many drug possession clients qualify.
Drug court and treatment probation. Riverside County and San Bernardino County both operate treatment courts, and prosecutors sometimes offer a treatment-based plea with dismissal or reduction on completion. Those programs typically require a plea first, which has immigration consequences that pure pretrial diversion avoids. Discuss the difference with counsel before choosing.
Reduction and later relief. A felony possession count for a defendant with a qualifying prior can sometimes be reduced to a misdemeanor under Penal Code section 17, subdivision (b). After probation, a conviction can generally be dismissed under Penal Code section 1203.4 using form CR-180 and CR-181. See how to expunge a criminal record in California.
Penalties and Collateral Consequences
Misdemeanor range. A misdemeanor conviction under either statute carries up to one year in county jail, though first offenders in the Inland Empire are far more often placed on probation with treatment conditions than jailed. Felony possession for the narrow class of defendants described above is punishable in county jail under Penal Code section 1170, subdivision (h). Possession for sale and transportation carry state-prison-range terms served locally in most cases. Exact terms depend on the charge and priors; do not rely on a general article for sentencing exposure.
Immigration. A controlled substance conviction is one of the most damaging outcomes for a noncitizen. Federal law makes most controlled substance convictions grounds for removal and inadmissibility, with a narrow exception for a single offense involving a small amount of marijuana. Under Padilla v. Kentucky (2010) 559 U.S. 356 and Penal Code section 1016.3, defense counsel must advise you about these consequences and the prosecutor must consider them. Pretrial diversion with no plea is usually the goal for a noncitizen client.
Driving, licenses, and custody. A drug conviction can affect commercial driving privileges and professional licenses issued by state boards, which generally require reporting of convictions. In family court, a drug conviction becomes evidence in custody disputes under the best-interest factors and can lead to testing orders. Our child custody page explains how criminal cases surface in custody litigation.
Firearms. A misdemeanor possession conviction does not by itself trigger the state felony firearm ban, but federal law prohibits firearm possession by an unlawful user of a controlled substance, and a felony conviction triggers the ban under Penal Code section 29800.
Where Drug Cases Are Heard in the Inland Empire and Los Angeles County
Courthouses. High Desert cases from Victorville, Hesperia, Apple Valley, and Adelanto are generally heard at the Victorville courthouse. San Bernardino, Fontana, Rialto, and Colton cases go to the San Bernardino Justice Center or the Fontana courthouse, and West End cases from Rancho Cucamonga, Ontario, and Upland go to the Rancho Cucamonga courthouse. Riverside, Moreno Valley, and Perris cases go to the Riverside Hall of Justice, and Temecula and Murrieta cases go to the Southwest Justice Center. Pomona cases go to the Pomona courthouse and Lancaster and Palmdale cases to the Antelope Valley courthouse. Confirm the courthouse on your citation and the court's current website.

Frequently Asked Questions
Is simple drug possession a felony in California?
Usually no. Simple possession under Health and Safety Code section 11350 and Health and Safety Code section 11377 is a misdemeanor after Proposition 47 unless you have a prior super strike conviction or must register as a sex offender. Possession for sale, transportation, and sale remain felonies, and Proposition 36 of 2024 created a treatment-mandated felony path for people with two or more prior drug convictions.
What does the prosecutor have to prove for drug possession?
Possession, knowledge of presence, knowledge of the drug's nature, a controlled substance, and a usable amount. Each element must be proven beyond a reasonable doubt, and each can be attacked. The usable quantity rule comes from People v. Leal (1966) 64 Cal.2d 504 and People v. Rubacalba (1993) 6 Cal.4th 62.
Can I get drug possession charges dismissed?
Often, yes. Pretrial diversion under Penal Code section 1000, judicial diversion under Penal Code section 1001.95, and mental health diversion under Penal Code section 1001.36 all end in dismissal on completion. A successful suppression motion under Penal Code section 1538.5 also usually ends the case.
Does a drug possession conviction affect immigration status?
Yes, seriously. Most controlled substance convictions make a noncitizen removable and inadmissible under federal law. Defense counsel must advise you under Padilla v. Kentucky (2010) 559 U.S. 356 and Penal Code section 1016.3. Pretrial diversion that requires no guilty plea is usually the safest path.
What if the drugs were not mine?
That is a knowledge and possession defense. The prosecutor must prove you knew the drugs were there, knew what they were, and had the right to control them. Under People v. Williams (1971) 5 Cal.3d 211, being near drugs is not possessing them. Do not try to explain this to the officer at the scene; explain it to your lawyer.
Can a felony drug charge be reduced to a misdemeanor?
Frequently. A possession-for-sale charge is often reduced to simple possession when the evidence of intent to sell is weak, and a wobbler possession count can be reduced under Penal Code section 17, subdivision (b). Reduction opens the door to diversion and later dismissal under Penal Code section 1203.4.
