Possession of a Controlled Substance: California Health and Safety Code 11350 HS

Possession of a controlled substance is one of the most frequently charged drug offenses in California.

Under California Health and Safety Code 11350 HS, it is illegal to possess certain narcotics, illegal street drugs, or prescription medications without a valid prescription from a licensed medical professional.

Following the passage of Proposition 47, most simple possession offenses for personal use are classified as misdemeanors rather than felonies.

However, a conviction still carries severe, life-altering consequences. Beyond potential jail time, a drug conviction creates a permanent criminal record that can jeopardize your employment, professional licensing, and immigration status.

If you or a loved one faces drug possession charges, early intervention by a top-tier legal team is vital. The experienced California criminal defense attorneys at Eisner Gorin LLP understand how to dismantle the prosecution's case and protect your future.

What Types of Drugs Fall Under HS 11350?

Health and Safety Code 11350 HS applies specifically to controlled substances regulated under federal and state law due to their high potential for abuse, addiction, or physical harm. These substances are categorized into distinct legislative "schedules":

Schedule I: High abuse potential with no recognized medical use (e.g., Heroin, LSD, Ecstasy).
Schedule II: High abuse potential but available via strict, heavily regulated medical prescriptions (e.g., Morphine, Oxycodone, Fentanyl, Codeine).
Schedules III, IV, & V: Progressively lower risks of abuse, consisting primarily of prescription anti-anxiety medications, mild painkillers, and stimulants (e.g., Ketamine, Xanax, Valium).

Statutory Note: Simple possession of methamphetamine is explicitly prosecuted under a separate statute—Health and Safety Code 11377 HS—though it shares nearly identical misdemeanor penalty structures for personal use.

Legal Definitions: The Three Types of "Possession"

To be charged with a violation of HS 11350, you do not necessarily need to be caught holding the drugs. California law recognizes three distinct forms of legal possession:

1. Actual Possession

This occurs when you have direct, physical control over the substance. Examples include law enforcement finding narcotics directly in your pockets, hand, purse, or backpack.

2. Constructive Possession

Constructive possession means the drugs were not on your person, but you maintained access to the location and had the "right to control" them. Examples include narcotics found inside your personal bedroom closet, a safe you own, or the glove box of your personal vehicle.

3. Joint Possession

This occurs when two or more individuals share immediate control over a controlled substance. For example, if roommates share an apartment and keep a stash of narcotics in a common living room cabinet to which they both have access, both can be charged with joint possession.

What Prosecutors Must Prove (Elements of the Crime)

To secure a conviction under Health and Safety Code 11350 HS, California prosecutors must establish five specific elements beyond a reasonable doubt:

Presence of a Controlled Substance: The material in question must be legally classified as a restricted controlled substance.
Exercise of Control: The defendant had actual, constructive, or joint possession of the drug.
Knowledge of Presence: The defendant was fully aware that the substance was present in their vicinity or possession.
Knowledge of Character: The defendant knew or should have known that the item was a regulated drug or controlled substance.
Usable Quantity: The amount found must be a usable quantity—meaning there is enough of the drug to be consumed or used to cause its effect. Minute chemical traces or empty residue are legally insufficient to sustain a conviction.

Real-World Case Example

The Scenario: Police conduct a traffic stop on a vehicle with a driver and a front-seat passenger. During a lawful search, officers find a small plastic baggie with five loose Oxycodone pills in the center console armrest. Neither person has a valid medical prescription for the medication.

The Legal Application: Because the pills were located in a shared central console accessible to both occupants, prosecutors may file joint constructive possession charges under HS 11350 against both the driver and the passenger. However, if the passenger can prove they had no prior knowledge that the driver had placed the pills in the console, the knowledge requirement fails, creating a strong path to dismissal.

Penalties and Sentencing for Drug Possession

Misdemeanor Penalties (The Standard)

Following Proposition 47, simple possession for personal use is an explicit misdemeanor for the vast majority of defendants. Conviction penalties include:

Up to one year in a California county jail.
Court-ordered fines of up to $1,000.
Formal or informal probation terms.

Felony Exceptions

A drug possession charge can still be elevated to a felony if the defendant has specific aggravating factors on their record.

This includes prior convictions for severe, violent crimes (such as murder or gross vehicular manslaughter) or registrable sex offenses. Felony drug convictions carry multi-year sentences in state prison.

Drug Diversion and Treatment Programs

Non-violent first or second-time offenders routinely qualify for drug diversion programs under Penal Code 1000 PC or Proposition 36. These alternative paths allow defendants to undergo court-approved drug rehabilitation and counseling.

The Ultimate Goal: If you successfully complete all components of your drug diversion program and comply with court conditions, your underlying criminal possession charges will be dismissed in full, keeping your record clean.

Common Legal Defenses to Dismiss or Reduce Charges

An arrest for a California drug crime does not guarantee a conviction. An aggressive criminal defense lawyer can leverage several legal strategies to fight the charges:

Valid Prescription: If you possess a legitimate, current prescription written by a licensed medical doctor, dentist, or podiatrist, you have an absolute defense to HS 11350.
Lack of Knowledge: If someone left drugs inside your vehicle, jacket, or home without your awareness, you cannot be held criminally liable because you lacked the necessary intent and awareness.
Fourth Amendment Violations (Illegal Search & Seizure): If law enforcement stopped your vehicle without reasonable suspicion or searched your home without a valid warrant or a clear legal exception, the evidence is tainted. We can file a Motion to Suppress Evidence (Penal Code 1538.5 PC). If successful, the judge will throw out the seized drugs, forcing the prosecution to drop the case.
Lack of Control/Dominion: Merely being near drugs does not equal possession. If you were present in a room where others used narcotics but had no ownership, control, or access to them, the possession element cannot be proven.

Related Offenses Under California Law

When prosecutors review an arrest file, they frequently attach secondary charges or elevate possession charges based on the surrounding evidence:

HS 11377 – Possession of Methamphetamine: The parallel misdemeanor statute governing simple possession of meth, ecstasy, and GHB.
HS 11351 – Possession of Controlled Substances for Sale: A strict felony offense triggered by signs of commercial intent, such as digital scales, large cash sums, individual baggies, or text messages arranging transactions. It does not qualify for drug diversion.
HS 11352 – Sale or Transportation of Controlled Substances: A severe felony targeting the distribution, sale, or physical movement of narcotics. Conviction can result in up to 9 years in state prison.
HS 11364 – Possession of Drug Paraphernalia: A misdemeanor charge for possessing pipes, needles, syringes, or spoons used to inject or smoke illegal substances.
HS 11550 – Being Under the Influence of a Controlled Substance: A misdemeanor focusing on your physical state of intoxication rather than physical possession of the drug itself.
HS 11370.1 – Drug Possession While Armed: A felony offense applied if a loaded, operable firearm is found within immediate physical reach of the controlled substance.

Frequently Asked Questions (FAQs)

Is drug possession a felony or a misdemeanor in California?

Thanks to Proposition 47, simple possession for personal use under HS 11350 is a misdemeanor for most individuals. It only becomes a felony if the defendant has specific severe priors on their record, such as sex offenses or violent felonies.

What counts as a "usable amount" under California law?

A usable amount means there is enough of the physical substance present to be consumed as a drug. Trace amounts, distinct chemical odors, or microscopic residue left inside a pipe or baggie are not enough to sustain a criminal conviction.

Will an HS 11350 conviction affect my immigration status?

Yes. Drug offenses are classified as crimes of moral turpitude or controlled substance violations under federal immigration law. Even a minor misdemeanor conviction can result in deportation, denial of citizenship, or visa revocation for non-citizens. Seeking immediate legal counsel is imperative to negotiate immigration-safe plea deals.

Can a drug possession charge be completely removed from my record?

Yes. If you qualify for and successfully complete a pretrial diversion program under PC 1000, your case will be dismissed. If you were already convicted and completed probation, you can petition the court for an expungement under Penal Code 1203.4 PC to clear your criminal history for employment purposes.

Can police search my vehicle for drugs without a search warrant?

Under the "automobile exception," police do not always need a warrant to search a vehicle, but they must have probable cause—such as clear sight of contraband, a distinct odor of narcotics, or an explicit admission of guilt. If they searched your car on a mere hunch, the search was illegal.
