California drug laws treat most simple possession as a misdemeanor, but Proposition 36, approved by voters in November 2024, added a new felony track for people with repeat drug convictions and steeper penalties tied specifically to fentanyl. About 5.6 million Californians aged 12 and older met the criteria for a substance use disorder between 2022 and 2023, and the state recorded 11,359 drug-related overdose deaths in 2023.1California Health Care Foundation. Substance Use in California Almanac – 2025 Edition2California Department of Public Health. Opioid-Related Overdose Deaths in California, 2023 The rules below cover what you can be charged with, what alternatives to jail exist, and where to turn for treatment or emergency help.
Possession Penalties
Since Proposition 47 took effect in November 2014, simple possession of a controlled substance for personal use is generally a misdemeanor.3California Courts | Self Help Guide. Record Cleaning: Felony Convictions and Proposition 47 Health and Safety Code 11350 covers drugs like cocaine, heroin, and certain prescription opioids without a valid prescription, with a maximum of one year in county jail.4California Legislative Information. California Health and Safety Code 11350 Health and Safety Code 11377 applies the same one-year maximum to methamphetamine and similar stimulants.5California Legislative Information. California Health and Safety Code 11377 Courts can add a fine of up to $70, but judges must consider ability to pay.
There is a significant exception. If you have a prior conviction for a serious or violent felony listed in Penal Code 667(e)(2)(C)(iv), or a prior conviction requiring sex offender registration, simple possession can be charged as a felony with a state prison sentence.4California Legislative Information. California Health and Safety Code 11350
What Proposition 36 Changed
Proposition 36 created a “treatment-mandated felony” for people with repeat drug convictions. If you have two or more prior convictions for drug possession or drug sales offenses and are caught possessing heroin, fentanyl, cocaine, or methamphetamine, prosecutors can charge the new offense as either a misdemeanor or a felony.6California Assembly Budget Committee. Criminal Laws Created or Amended by Proposition 36 If charged as a felony, the punishment is up to three years in county jail for a first offense or three years in state prison for a subsequent one.
The law gives defendants an alternative to incarceration. A person charged with a treatment-mandated felony can plead guilty, waive sentencing, and enter a court-approved treatment program that may include drug treatment, mental health care, and job training. Completing the program results in the felony being dismissed. Failing to complete it means the court can impose the original prison or jail sentence.7California Secretary of State. Proposition 36 Text of Proposed Laws
Proposition 36 also reworked fentanyl-related penalties beyond simple possession:
- For drug sales cases, the threshold for weight-based sentence enhancements dropped to one ounce for fentanyl, down from one kilogram, adding three to 25 years depending on the quantity involved.
- Possessing fentanyl while armed with a loaded firearm is now a felony carrying up to four years in prison. Before Prop 36, fentanyl was not on the list of drugs triggering this charge.
- A new four-year sentencing enhancement applies when someone suffers serious injury from drugs that were sold or given to them.
Sales and Trafficking
California draws a sharp line between possessing drugs for personal use and possessing them for sale. Under Health and Safety Code 11351, possessing a controlled substance with the intent to sell carries two, three, or four years in state prison.8California Legislative Information. California Health and Safety Code 11351 Health and Safety Code 11352 sets the base sentence for transporting or selling drugs at three, four, or five years. Transporting across noncontiguous county lines pushes the range to three, six, or nine years.9California Legislative Information. California Health and Safety Code 11352
Federal law adds another layer for larger cases. Under 21 U.S.C. 841, distributing threshold quantities of Schedule I or II drugs triggers mandatory minimum sentences. For example, 100 grams or more of heroin, 40 grams or more of fentanyl, or 28 grams or more of crack cocaine carry a minimum of five years in federal prison. Larger quantities (1 kilogram of heroin, 400 grams of fentanyl, or 280 grams of crack) trigger a 10-year mandatory minimum. If death or serious injury results, the minimum jumps to 20 years.10Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
Alternatives to Jail Through Drug Diversion
Penal Code 1000 offers a pretrial diversion path for people charged with certain drug offenses, including simple possession, being under the influence, and possessing drug paraphernalia. The court postpones prosecution while you complete a drug treatment program. To qualify, you must have no drug conviction within the past five years (other than the listed eligible offenses), the charge cannot involve violence or threatened violence, and you cannot have a prior felony conviction within five years.
Proposition 36’s treatment-mandated felony is a separate track aimed at repeat offenders. Where PC 1000 keeps eligible people out of the criminal justice system entirely, the treatment-mandated felony requires a guilty plea before entering treatment, with dismissal of the felony as the reward for completion.7California Secretary of State. Proposition 36 Text of Proposed Laws Courts, prosecutors, or probation officers can terminate the treatment at any time if the person is not participating meaningfully, which triggers sentencing on the original charge.
Calling 911 During an Overdose
California’s Good Samaritan law, Health and Safety Code 11376.5, protects people who call for emergency help during an overdose. If you call in good faith, you cannot be charged with being under the influence, possessing drugs or paraphernalia for personal use, or being present in a place where drugs are used.11California Legislative Information. California Health and Safety Code 11376.5 The same protection extends to the person overdosing, as long as someone at the scene sought medical help. The immunity does not cover drug sales, forcibly giving someone drugs, or offenses like DUI.
Naloxone, the opioid overdose reversal medication, is widely available. Under Business and Professions Code 4052.01, pharmacists can furnish naloxone directly to patients without an individual prescription, following standardized protocols from the Board of Pharmacy and the Medical Board of California.12California Legislative Information. California Business and Professions Code 4052.01 Laypersons who administer naloxone to someone they reasonably believe is overdosing are protected from civil and criminal liability.
Treatment Through Medi-Cal
California’s publicly funded treatment system runs primarily through the Drug Medi-Cal Organized Delivery System, which uses the American Society of Addiction Medicine criteria to match each person to the right level of care. Options range from outpatient counseling and medication-assisted treatment to residential programs and medically supervised withdrawal management.13California Health Care Foundation. Drug Medi-Cal Organized Delivery System
The state’s CalAIM initiative operates under a “no wrong door” policy for behavioral health. Medi-Cal beneficiaries can receive mental health and substance use disorder services without delay regardless of which part of the delivery system they contact first, and services are covered during the initial assessment period, before a formal diagnosis is established.14Department of Health Care Services. BHIN 22-011 No Wrong Door for Mental Health Services Policy In practice, you can walk into a county behavioral health office or call your Medi-Cal managed care plan and get started.
For non-emergency situations, the Department of Health Care Services operates a statewide referral line at (800) 879-2772. The automated system connects you to your local county alcohol and drug program office, which can provide information about available services and help coordinate intake.15Department of Health Care Services. SUD Non-Emergency Treatment Referral Line
Insurance, Job Protection, and Medical Leave
Private health insurance plans, under the federal Mental Health Parity and Addiction Equity Act, must cover substance use disorder treatment on terms comparable to medical and surgical care. Plans cannot impose stricter prior authorization, higher copays, or more limited visit counts on addiction treatment than on comparable medical services.16Federal Register. Requirements Related to the Mental Health Parity and Addiction Equity Act Starting in 2026, insurers must produce detailed data showing that their mental health and substance use disorder restrictions are no more burdensome than those for physical health conditions.
Costs vary widely by plan. A 30-day residential program can range from roughly $4,000 to over $30,000 for self-pay patients, while intensive outpatient programs typically run $100 to $350 per day. Contact your insurer before admission to confirm what the plan covers and what cost-sharing to expect.
The Americans with Disabilities Act protects people in recovery. If you have completed a rehabilitation program, are currently enrolled in one and no longer using drugs, or are erroneously perceived as using drugs, an employer cannot fire or refuse to hire you based on your history of addiction.17U.S. Commission on Civil Rights. Sharing the Dream: Is the ADA Accommodating All? Employers can still enforce workplace drug policies, test for illegal drug use, and discipline employees for on-the-job impairment. Current illegal drug use is not protected.
The Family and Medical Leave Act provides up to 12 weeks of unpaid, job-protected leave for eligible employees seeking substance abuse treatment through a healthcare provider. Your employer must maintain your health benefits during the leave and allow you to return to the same or an equivalent position. FMLA leave covers residential treatment, medically supervised detox, and structured outpatient therapy, but it does not shield you from discipline for workplace conduct violations that occurred before you took leave.18eCFR. 29 CFR 825.119 – Leave for Treatment of Substance Abuse Employees in safety-sensitive transportation roles (commercial drivers, pilots, railroad workers, pipeline operators) face additional mandatory drug testing under Department of Transportation regulations, and a positive test or refusal triggers removal from duty and a formal return-to-duty process.
