Is Heroin Legal in California?

Under California Health and Safety Code Section 11350, simple possession of heroin for personal use is a misdemeanor following Proposition 47. Penalties include up to one year in county jail and a fine of up to $1,000. Prior to Prop 47, heroin possession was a felony offense.

Many heroin possession cases in California are resolved through drug diversion programs rather than incarceration. Proposition 36 and Penal Code 1000 allow eligible defendants to complete substance abuse treatment instead of serving jail time. Drug courts provide another alternative, offering structured treatment and supervision for individuals with substance use disorders involved in the criminal justice system.

Sale, transport, and distribution of heroin remain serious felonies in California. Under Health and Safety Code Section 11352, selling or transporting heroin carries 3 to 5 years in state prison. Sentences are enhanced for sales near schools, involving minors, or in large quantities.

Heroin is a highly addictive opioid that binds to receptors in the brain, producing intense euphoria followed by sedation. The drug is typically injected, smoked, or snorted, and each route carries serious health risks. Injection use increases risk for HIV, hepatitis C, bacterial endocarditis, and abscesses.

Heroin overdose is a leading cause of accidental death, causing respiratory depression that can stop breathing entirely. The risk of fatal overdose has increased dramatically due to the adulteration of heroin with illicit fentanyl. Much of the heroin sold in Los Angeles now contains fentanyl, often without the user's knowledge.

Heroin addiction is a treatable medical condition. Medication-assisted treatment (MAT) is the gold standard for opioid use disorders, combining FDA-approved medications — methadone, buprenorphine (Suboxone), or naltrexone (Vivitrol) — with behavioral counseling and support services.

Los Angeles has a comprehensive network of heroin addiction treatment providers, including methadone maintenance programs, buprenorphine clinics, residential treatment centers, and outpatient programs. Medically supervised detox is recommended as the first step, followed by long-term MAT and counseling to support sustained recovery.
