Simple drug possession in California is usually a misdemeanor, and the most serious exposure is up to one year in county jail. Felony treatment is the exception. It applies mainly to people with specific prior convictions, and since Proposition 36 it also applies to some hard-drug possession cases. Many first-time cases never end in a conviction at all, because diversion and treatment programs can lead to dismissal.
This guide covers the penalties for possession under Health and Safety Code (HSC) 11350, what moves a case from misdemeanor to felony, how Prop 36 changed things, and what options exist before a conviction. We practice criminal defense in San Diego, so we also say where we see cases turn.
TL;DR
- Possession of a controlled substance without a valid prescription under HSC 11350 carries up to one year in county jail, plus fines, fees and conditions.
- Certain prior convictions push punishment into the felony range under Penal Code 1170(h).
- Prop 36 (effective December 18, 2024) created a treatment-mandated felony for hard-drug possession by people with two or more qualifying priors.
- Diversion under Penal Code 1000 or 1001.95, or court-approved treatment, can end in dismissal if you complete it.
- What happens in the first weeks, including any search or stop issues, shapes every option that follows.

What the statute says about simple possession
HSC 11350 covers possession of specified controlled substances, such as cocaine and heroin, without a valid prescription. Under the statute, possession without a written prescription is punishable by up to one year in county jail, and any discretionary fine may not exceed $70. People with qualifying prior convictions must be punished under Penal Code 1170(h) instead.
You will see higher figures on other sites, usually "up to $1,000." That number comes from the broader rules for fines and for probation conditions, not from the fine line in the possession statute. In practice, what a person actually pays is a stack of items:
- the base fine, if the court imposes one
- penalty assessments and surcharges
- a $50 criminal lab fee on specified drug offenses; the California Supreme Court has held that criminal lab and drug program fees are punishment
- program costs for drug education or treatment
- probation supervision conditions
That last point matters more than the headline fine. Probation on a drug case commonly means testing, classes and a period of supervision, and a violation can bring the jail exposure back into play.
Other substances have their own statutes
HSC 11350 is not the only possession statute. Methamphetamine, for example, falls under a different section, and personal-use cannabis has its own rules. The same logic applies across them: possession is the lowest tier, and charges for possessing with intent to sell, selling, or transporting are far more serious. If your paperwork lists anything beyond plain possession, read the charge carefully. We explain the difference on our pages for drug sales and drug transportation.
Misdemeanor or felony: what changes the charge
The word "possession" does not decide the level of the charge. Your record and the substance do.
Prior convictions. A person with one or more prior convictions for a specified offense, or for an offense requiring sex-offender registration under Penal Code 290(c), is punished under Penal Code 1170(h). That is the felony-range sentencing structure, served in county jail in many cases rather than state prison.
Felony probation terms. If you are placed on probation after a felony conviction under HSC 11350, the statute requires, except in unusual cases where justice does not so require, a fine of at least $1,000 for a first offense or $2,000 for a later one, or community service. This is probably the source of the $1,000 figure many readers see.

Prop 36 and hard drugs. This is the biggest recent change, covered next.
Quick comparison
| Situation | What the law provides | Where it comes from |
|---|---|---|
| Simple possession, no qualifying priors | Up to one year in county jail; discretionary fine capped at $70 | HSC 11350 |
| Possession with qualifying priors | Punishment under Penal Code 1170(h) | HSC 11350 |
| Hard-drug possession, two or more qualifying priors | Treatment-mandated felony under HSC 11395 | HSC 11395 |
| Eligible first-time or low-level case | Possible diversion and dismissal | Penal Code 1000 |
Proposition 36 and the new hard-drug felony
Voters approved Proposition 36 in November 2024, and it took effect on December 18, 2024. It created a treatment-mandated felony for possession of hard drugs under HSC 11395, aimed at defendants with two or more prior convictions for specified drug-related offenses. The statute treats fentanyl, heroin, cocaine and methamphetamine as hard drugs. Cannabis and certain psychedelic substances are excluded.
The punishment under HSC 11395 is up to one year in county jail or a sentence under Penal Code 1170(h). A second or later conviction is punishable by up to one year in county jail or state prison.
Three practical points:
- Treatment is the center of the statute. A defendant may elect court-approved treatment instead of jail, prison, or probation with jail. With successful completion, a positive program recommendation and a motion, the charge is dismissed.
- Release after arrest is not automatic. On arrest for an HSC 11395 violation, judicial review is required before release to assess risk to public safety and the likelihood of returning to court.
- Prosecutors still choose. The state's court report notes that Prop 36 permits felony charges for defendants with two or more prior drug convictions, while some eligible cases are filed as misdemeanors. Filing decisions vary by county and by case.
Courts are also adjusting. The state allocated $20 million in the 2025 Budget Act to the judicial branch for the added caseload and collaborative-court needs, and a pending bill, SB 926, would set up a fund for Prop 36 implementation. Treatment capacity and local practice may keep shifting, so check current conditions with a lawyer who works in the court where your case sits.
How diversion can keep a conviction off your record
For many people the most important question is not the maximum penalty but whether there will be a conviction at all.
Penal Code 1000 pretrial diversion
Penal Code 1000 allows eligible defendants to enter pretrial diversion. After successful completion, the court dismisses the charges. To qualify, a defendant typically must have no conviction for a controlled substance offense in the past five years and no prior felony convictions in that period. Our page on pretrial diversion in San Diego walks through how that process runs locally.
Penal Code 1001.95 misdemeanor diversion
Penal Code 1001.95 gives trial courts discretion to offer misdemeanor diversion over a prosecutor's objection, unless the defendant falls under specific exclusions such as domestic violence or a sex-offender registration requirement. This matters because a prosecutor saying no is no longer the end of the road. We cover the mechanics in our guide to PC 1001.95 misdemeanor diversion, and the process before a judge on our judicial diversion page.
Other routes
- Military diversion. Veterans and service members may be eligible under PC 1001.80. See our guide to military diversion in California.
- Mental health diversion. When a diagnosed condition played a role in the offense, mental health diversion under PC 1001.36 may apply.
- Treatment under Prop 36. For HSC 11395 cases, the treatment election described above.
Eligibility turns on details: your record, the substance, whether other charges are attached, and what the judge and prosecutor will accept. Do not assume you are in or out until a lawyer has read the actual file.
Defenses that can apply to a possession charge
A possession case is built on the prosecution proving several things: that you had the substance, knew of its presence and nature, and that it was a usable amount of a controlled substance. Each is a place to push. These are general categories, and which ones apply depends on the facts.

Unlawful search or stop. Most possession cases begin with a traffic stop, a vehicle search or a search of a person or home. If officers lacked legal grounds, a motion to suppress can remove the drugs from the case, and without the drugs there is often no case. Details of what the officers said and did, including any footage, can decide this. If you or a bystander captured the stop, recording police in California is worth understanding, including how to preserve what you recorded.
Lack of knowledge or control. Drugs found in a shared car, a shared home or another person's bag raise a genuine question about whose they were. Presence near a substance is not the same as possession.
Valid prescription. Possession "without a written prescription" is the offense, so a valid prescription in your name is a direct answer for medications.
Lab and chain-of-custody issues. The substance has to be what the state says it is, in a measurable amount, handled properly from seizure to testing.
Diversion as a strategy. Even where the evidence is strong, the realistic goal may be a dismissal through diversion rather than a trial.
What to do in the first days after an arrest
- Do not discuss the case with police or on the phone from jail. Say you want a lawyer and stop talking.
- Write down what happened. Where you were stopped, what officers asked, whether you consented to any search, who else was there.
- Keep paperwork. Citation, release papers, property receipts and any court dates.
- Do not miss court. A missed date creates a warrant and a second problem. If one already exists, see our warrants and probation page.
- Ask early about diversion. Some options depend on timing and on the prosecutor's offer, so earlier is better.
- Think about your job. Professionals with licenses, commercial drivers and people with immigration or military status face consequences beyond jail. Tell your lawyer on day one.
Our perspective
We see two mistakes. The first is panic: people read a maximum of one year in jail and assume that is the likely outcome. For a first-time possession charge, it rarely is, and the better question is which off-ramp is available. The second is complacency: people assume "it's just possession" and plead at the first hearing, then discover the plea counts as a conviction for licensing, employment, immigration or later sentencing.
Our approach starts before the plea. We look at how the drugs were found, whether the stop and search hold up, and which diversion program fits the person. Then we build the story the judge will hear: who you are, what was going on, and why treatment and accountability serve everyone better than a record. Logan's background as a published writer and journalist shapes that work, and so does his experience in diversion programs. Prop 36 makes it more important to get involved early, because the way a case is filed in its first days can change which options are even open.

FAQ
Is drug possession a felony in California?
Usually not. Simple possession under HSC 11350 is punishable by up to one year in county jail, and qualifying prior convictions move punishment to Penal Code 1170(h). Prop 36 also created a felony for hard-drug possession by people with two or more qualifying priors, though prosecutors file some eligible cases as misdemeanors.
Can I avoid jail for a first possession charge?
Often, yes. Eligible defendants can seek diversion under Penal Code 1000 or 1001.95, and successful completion leads to dismissal. Whether you qualify depends on your record and the specifics of the charge, so have an attorney review your file.
What drugs count as hard drugs under Prop 36?
HSC 11395 includes substances such as fentanyl, heroin, cocaine and methamphetamine. It excludes cannabis and certain psychedelic substances. The felony requires two or more prior convictions for specified drug-related offenses.
What fines and fees come with a possession conviction?
The statute caps a discretionary fine at $70, but felony probation carries minimum fines of $1,000 for a first offense or $2,000 for a later one, absent unusual circumstances. A $50 criminal lab fee, assessments and program costs can add to the total.
Can a possession conviction be cleared later?
In many cases, yes. Expungement, early termination of probation and record sealing may be available depending on the outcome and your completion of probation. A lawyer can tell you which apply to your case.
