Possession of a Controlled Substance under California Health and Safety Code § 11350(a) generally involves knowingly possessing certain controlled substances without a valid prescription or other legal authorization. The offense is generally a misdemeanor punishable by up to one year in county jail, although qualifying prior convictions can result in felony punishment.
Understanding what the law prohibits, what prosecutors must prove, and what defenses may apply is important for anyone facing a California drug possession charge.
What Is California Health and Safety Code § 11350(a)?
California Health and Safety Code § 11350(a), commonly called HS 11350(a), makes it unlawful to possess specified controlled substances without the required legal authorization.
The statute covers certain narcotics and other controlled substances identified in California’s statutory drug schedules.
Examples include:
- Cocaine: Including cocaine base.
- Heroin: An illegal opioid.
- Certain prescription narcotics: Specified Schedule III, IV, and V narcotic drugs possessed without lawful authorization.
- Other listed controlled substances: Depending on their classification under California law.
Not every drug possession offense falls under HS 11350(a). For example, methamphetamine possession is generally prosecuted under Health and Safety Code § 11377.
The specific substance involved determines which California drug possession statute applies.
What Must the Prosecutor Prove Under HS 11350(a)?
To obtain a conviction, the prosecution must prove every required element beyond a reasonable doubt.
Under CALCRIM No. 2304, the California jury instruction for simple possession of a controlled substance, the prosecution generally must establish:
- The defendant possessed a controlled substance.
- The defendant knew the substance was present.
- The defendant knew of the substance’s nature or character as a controlled substance.
- The substance was a controlled substance covered by the applicable statute.
- The substance was present in a usable amount.
What Does Possession Mean?
California recognizes two primary forms of possession:
- Actual possession: Physically holding or carrying the controlled substance.
- Constructive possession: Having control over the substance or the right to control it, even without physically holding it.
For example, cocaine discovered inside someone’s pocket may establish actual possession. Drugs stored inside a locked personal cabinet may support constructive possession.
However, simply being near a controlled substance does not automatically establish criminal possession.
Does the Defendant Have to Know What Drug They Possess?
The defendant must know that the substance is present and know its nature or character as a controlled substance. However, prosecutors generally do not have to prove that the defendant knew its precise chemical identity.
For example, someone may know they are possessing an illegal narcotic without knowing whether it is cocaine or heroin.
What Is a Usable Amount?
A usable amount is a quantity sufficient for someone to use as a controlled substance. Insignificant residue or useless debris generally does not qualify.
A small quantity may still satisfy this requirement if it is sufficient for use. The substance does not have to be enough to produce a particular physical or psychological effect.
Is Possession of a Controlled Substance a Misdemeanor or Felony in California?
Possession under HS 11350(a) is generally a misdemeanor following the passage of Proposition 47 in 2014.
A standard misdemeanor conviction carries a potential sentence of up to one year in county jail.
However, certain qualifying prior convictions can result in felony punishment.
When Can HS 11350(a) Become a Felony?
HS 11350(a) contains an exception for individuals with certain prior convictions.
A person with one or more qualifying prior convictions identified in Penal Code § 667(e)(2)(C)(iv), or a prior conviction requiring registration under Penal Code § 290(c), may face felony punishment under Penal Code § 1170(h).
Additionally, Proposition 36 introduced Health and Safety Code § 11395, which establishes a separate treatment-mandated felony offense.
This law applies to individuals who possess specified hard drugs and have at least two qualifying prior convictions for certain drug offenses.
Covered substances include:
- Fentanyl.
- Heroin.
- Cocaine.
- Cocaine base.
- Methamphetamine.
- PCP.
HS 11395 has separate requirements and treatment provisions. It does not automatically turn every HS 11350(a) charge into a felony.
What Are the Penalties for Possession of a Controlled Substance?
The penalties depend on the defendant’s criminal history and the applicable statutory provisions.
For an ordinary misdemeanor violation of HS 11350(a), potential consequences include:
| Penalty | Description |
|---|---|
| County jail | Up to one year. |
| Fine | Up to $70 under HS 11350(b), subject to applicable ability-to-pay provisions. |
| Probation | May be available depending on the circumstances. |
| Drug treatment | May be available through qualifying diversion programs. |
| Criminal record | A conviction may affect employment and other opportunities. |
Felony punishment may apply when qualifying prior convictions trigger the statutory exception.
Can You Go to Jail for Simple Drug Possession?
Yes. A misdemeanor conviction under HS 11350(a) can result in up to one year in county jail.
However, incarceration is not automatic. Depending on the circumstances, probation, treatment, or diversion may be available.
Can You Get Drug Diversion for a Possession of Controlled Substance Charge?
Yes. Eligible defendants charged under HS 11350(a) may qualify for California’s pretrial drug diversion program under Penal Code § 1000.
The program focuses on drug education and treatment rather than traditional criminal punishment.
Eligibility depends on statutory requirements, including:
- Whether the defendant has a disqualifying controlled substance conviction within the preceding five years.
- Whether the charged offense involved violence or threatened violence.
- Whether there is evidence of another disqualifying contemporaneous drug-related offense.
- Whether the defendant has a disqualifying felony conviction within the preceding five years.
The prosecuting attorney reviews the applicable eligibility requirements.
What Happens After Successfully Completing Drug Diversion?
Successful completion of the applicable diversion program can result in dismissal of the qualifying charges.
The program generally involves education or treatment requirements and compliance with the court-approved process.
A successful dismissal can allow an eligible defendant to avoid a criminal conviction for the qualifying offense.
However, diversion is not automatic. The defendant must satisfy the statutory eligibility requirements and complete the program successfully.
What Are the Legal Defenses to an HS 11350(a) Charge?
Several legal defenses may apply to a California controlled substance possession charge. The appropriate defense depends on the evidence and circumstances of the arrest.
1. Lack of Knowledge
The prosecution must establish that the defendant knew the controlled substance was present and knew its nature or character as a controlled substance.
For example, someone who unknowingly carries another person’s bag containing cocaine may challenge the allegation based on lack of knowledge.
2. Lack of Possession
Being near drugs does not automatically mean someone possesses them.
A defendant may challenge the charge if there is insufficient evidence that they exercised control over the substance or had the right to control it.
Example: Police discover cocaine inside a locked container belonging to one roommate. Other roommates may challenge possession allegations if there is no evidence connecting them to the container or its contents.
3. Valid Prescription
A qualifying written prescription may provide a defense to unlawful possession.
The prescription must satisfy the applicable California legal requirements and cover the substance involved.
4. Insufficient Quantity
The prosecution must establish that the substance was present in a usable amount.
Insignificant residue or unusable debris may not satisfy this requirement.
5. Illegal Search and Seizure
The Fourth Amendment protects individuals against unreasonable searches and seizures.
If police obtained the alleged controlled substance through an unlawful search, the defense may challenge the evidence under California Penal Code § 1538.5.
If the court grants a motion to suppress, evidence obtained through the unlawful search may be excluded from the criminal proceedings.
6. Incorrect Drug Identification
The prosecution must establish that the substance is actually covered by HS 11350(a).
Laboratory testing and evidence handling may become important when challenging the identification of the alleged controlled substance.
What Is the Difference Between Simple Possession and Possession for Sale?
Simple possession and possession for sale are separate criminal offenses under California law.
HS 11350(a) addresses unlawful possession of specified controlled substances. Possession for sale is generally prosecuted under other statutes, including HS 11351 and HS 11351.5, depending on the substance.
Evidence that may suggest possession for sale includes:
- Large quantities of controlled substances.
- Individually packaged drugs.
- Scales and packaging materials.
- Records of drug transactions.
- Communications concerning drug distribution.
For example, a person found with individually packaged quantities of cocaine and other evidence suggesting distribution may face a possession-for-sale charge instead of simple possession.
However, prosecutors must prove the elements of the separate offense. The presence of packaging materials or large quantities alone does not automatically establish intent to sell.
What Happens After an Arrest for Drug Possession in California?
An arrest under HS 11350(a) begins the criminal process, but it does not mean the defendant has been convicted.
The process generally includes:
- Arrest and booking: Law enforcement records the arrest and processes the individual.
- Arraignment: The defendant appears in court, is informed of the charges, and enters a plea.
- Pretrial proceedings: The prosecution and defense review evidence and address legal issues, including possible motions to suppress evidence.
- Case resolution: The case may proceed through dismissal, diversion when eligible, a negotiated resolution, or trial.
During these proceedings, the defense may challenge the evidence, examine the legality of the search, and evaluate available legal options.
Understanding the charges and available defenses early can help individuals make informed decisions about their cases.
Can a California Drug Possession Conviction Be Expunged?
In some circumstances, yes.
Under California Penal Code § 1203.4, eligible individuals may petition the court for dismissal of certain convictions.
Eligibility generally depends on factors such as successful completion of probation, completion of the sentence, and compliance with other statutory requirements.
A successful dismissal may provide benefits when applying for employment and pursuing other opportunities.
However, dismissal does not erase every consequence of a conviction. Certain government, licensing, and immigration-related proceedings may still consider the underlying record.
Individuals with qualifying older felony drug possession convictions may also explore redesignation under Penal Code § 1170.18, established by Proposition 47.
