A straightforward possession charge under California Health and Safety Code 11350(a) is a misdemeanor, not a felony. That has been the default since voters passed Proposition 47 in 2014, and it still holds for most people arrested with heroin, cocaine, fentanyl, prescription opioids, or the other controlled substances the statute covers.1California Legislative Information. California Health and Safety Code 11350 Two things push a case out of misdemeanor territory: a narrow set of prior convictions that strip Proposition 47’s protection, and a new treatment-mandated felony track created by the 2024 Proposition 36 for people with multiple prior drug offenses.2Legislative Analyst’s Office.

The Misdemeanor Default
For a first-time or otherwise unremarkable possession case, 11350(a) carries a maximum of one year in county jail.1California Legislative Information. California Health and Safety Code 11350 A base fine of up to $1,000 is available under California’s general misdemeanor rules, but in practice most people without a significant record are placed on probation with treatment conditions rather than sentenced to jail time.
The base fine is only the starting number. State and county penalty assessments, court construction fees, DNA fund assessments, and other add-ons stack on top of every criminal fine. A $390 base fine for a comparable misdemeanor, for example, generates roughly $1,800 in total assessments and fees.3Legislative Analyst’s Office. Overview of Criminal Fine and Fee System Anyone budgeting for the real cost of a conviction should assume the number on the citation is not the number they will pay.
Probation is usually informal or supervised, can last up to three years, and typically includes drug testing, community service, and a treatment or education program. A probation violation can trigger revocation and the originally suspended jail time.
One drug-specific note: 11350(a) does not cover everything illegal. Methamphetamine is charged under Health and Safety Code 11377, and cannabis lives under its own regulatory framework. The statute reaches heroin, morphine, codeine, hydrocodone, oxycodone, hydromorphone, fentanyl, powder cocaine, crack cocaine, peyote, mescaline, GHB, methaqualone, and any Schedule III–V narcotic possessed without a valid prescription.4California Legislative Information. California Health and Safety Code 11054
When 11350(a) Is Charged as a Felony
Proposition 47’s misdemeanor reclassification carved out two categories of people. For them, simple possession is still filed as a felony from the start.
Prior Super Strike Convictions
If you have a prior conviction for one of the offenses listed in Penal Code 667(e)(2)(C)(iv), often called a “super strike,” a 11350(a) charge is filed as a felony. That list includes homicide and attempted homicide, sexually violent offenses, certain sex crimes against children under 14, solicitation to commit murder, assault with a machine gun on a peace officer, and any serious or violent felony punishable by life imprisonment or death.5California Legislative Information. California Penal Code 667
Sex Offender Registration
Anyone required to register as a sex offender under Penal Code 290(c) faces felony prosecution under 11350(a), whether or not the underlying offense qualifies as a super strike.1California Legislative Information. California Health and Safety Code 11350
Felony Sentence Range
A felony 11350(a) conviction is sentenced under Penal Code 1170(h): 16 months, two years, or three years in county jail.6California Legislative Information. California Penal Code 1170 If the court grants felony probation instead, it must impose a minimum fine of $1,000 for a first offense, $2,000 for a second, and $3,000 for a third, or order community service in place of the fine.
The Treatment-Mandated Felony Track Under Proposition 36
The Homelessness, Drug Addiction, and Theft Reduction Act took effect in December 2024 and created a new Health and Safety Code section 11395. It applies to people who possess a “hard drug” and have two or more prior convictions for drug offenses such as possession, possession for sale, transportation, or manufacturing.2Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Hard drugs under this provision include fentanyl, heroin, cocaine, methamphetamine, and PCP. Cannabis, peyote, LSD, psilocybin mushrooms, and mescaline are explicitly excluded.
The track is designed to move repeat offenders into treatment rather than jail. Completing court-ordered mental health or drug treatment ends in dismissal. Refusing or failing treatment carries up to three years in state prison.2Legislative Analyst’s Office. Proposition 36 Ballot Analysis Before December 2024, someone with several prior simple-possession convictions still faced only misdemeanor consequences on a new 11350(a) charge. That is no longer true if hard drugs and qualifying priors are involved.
What the Prosecution Has to Prove Either Way
Whether the case is charged as a misdemeanor or a felony, the elements are the same. A conviction requires proof beyond a reasonable doubt of three things: possession, knowledge, and a usable amount.
Possession can be actual — the drug is on your body or in your hand — or constructive, meaning you had the right to control the substance even though it wasn’t on you at the moment police found it. Pills in a glove box or a nightstand drawer qualify. Access and control matter, not physical contact.
Knowledge means you knew the substance was there and understood it was a controlled drug. You don’t need to know the chemical name; knowing you had “something illegal” is enough. If a friend left a package in your trunk without telling you, that missing knowledge can defeat the charge.
Usable amount is a real threshold. Trace residue on a pipe, powder smudges on clothing, or microscopic particles scraped from a surface are not enough. The California Supreme Court has held that the law reaches a substance with “narcotic potential” as a usable commodity, not “useless traces or residue.”7Justia Law. People v. Rubacalba (1993) The substance need not be pure, but it must exist in a form and quantity someone could actually consume.
A valid prescription from a licensed physician, dentist, podiatrist, or veterinarian is a complete defense for prescription drugs like hydrocodone or oxycodone.1California Legislative Information. California Health and Safety Code 11350
Diversion and Dismissal
Even when a 11350(a) charge sticks as a misdemeanor, a conviction is not the only outcome. Two mechanisms can keep the case off your record.
Pretrial Diversion Under Penal Code 1000
Penal Code 1000 lists 11350 as a qualifying offense for pretrial diversion.8California Legislative Information. California Penal Code 1000 Older cases sometimes call it “Deferred Entry of Judgment,” but the current statute is pretrial diversion. To qualify, all four of these must be true: no controlled substance conviction within the past five years other than the qualifying offenses listed in the statute, no crime of violence in the current charge, no evidence of a simultaneous drug offense outside the listed categories, and no prior felony conviction within the past five years.
The prosecutor evaluates eligibility and files a declaration with the court. If accepted, you complete a certified drug education or treatment program. Successful completion and staying out of trouble during the diversion period result in dismissal, with no conviction on your record. Failure sends the case back into normal criminal proceedings.
Dismissal After Probation Under Penal Code 1203.4
After finishing probation and meeting all court-ordered conditions, you can petition for dismissal under Penal Code 1203.4. The court withdraws your guilty plea, enters a not-guilty plea, and dismisses the case. For a misdemeanor, the petition is available once probation is complete. If probation was denied, you can apply one year after the conviction date.
A 1203.4 dismissal helps with most private employment background checks, but the conviction remains visible for sex offender registration purposes and, importantly, for federal immigration proceedings.
The Immigration Caveat
For a non-citizen, whether a 11350(a) case ends in a misdemeanor, felony, dismissed diversion, or 1203.4 dismissal is not the end of the analysis. Under federal law, a “conviction” exists whenever someone enters a guilty plea or admits enough facts to support a finding of guilt and a judge orders any form of punishment or restraint on liberty, regardless of whether the state later dismisses the case.9Cornell Law Institute. 8 USC 1101(a)(48) – Definition of Conviction California reformed PC 1000 to operate as true pretrial diversion with no plea required, which should avoid triggering the federal definition. A 1203.4 dismissal does not. Anyone who is not a citizen should get immigration-specific advice before entering any plea, diversion program, or dismissal petition on a drug charge.
