California’s harm reduction laws give people meaningful legal cover in three main situations: calling 911 during an overdose, carrying or giving someone naloxone, and possessing syringes or fentanyl test strips obtained through legal channels. The protections are real but narrow in specific ways, and some of them sit uneasily next to federal law. Knowing where each one stops matters as much as knowing it exists.
If You Call 911 During an Overdose
California’s Good Samaritan overdose law, Health and Safety Code Section 11376.5, protects two groups of people from certain drug charges when someone calls for medical help.1California Legislative Information. California Health and Safety Code HSC 11376.5 If you call 911 for someone who is overdosing, you cannot be prosecuted for personal-use possession of controlled substances, being under the influence, or possession of drug paraphernalia for personal use. If you are the person overdosing and someone at the scene calls for help, you get the same protection.
Two conditions apply. You have to act in good faith, and you cannot obstruct medical or law enforcement personnel who respond.1California Legislative Information. California Health and Safety Code HSC 11376.5
The limits are important. The immunity covers personal possession and being under the influence. It does not cover sales or distribution charges. It does not cover DUI or other offenses that involve dangerous conduct while impaired. The statute itself says no broader immunity should be read into it beyond what the text spells out. If you are carrying an amount a prosecutor could treat as for-sale, or if you drove to the scene impaired, the Good Samaritan protection will not reach those charges.
Carrying and Giving Someone Naloxone
Naloxone, often sold as Narcan, reverses opioid overdoses within minutes. California has made it legal to obtain, carry, and administer in several overlapping ways.
The state public health officer at the California Department of Public Health has issued a statewide standing order that lets a wide range of community organizations distribute naloxone without an individual prescription. Eligible distributors include first responders, schools, libraries, homeless programs, veteran organizations, courts, and community groups.2California Department of Public Health. CDPH Statewide Naloxone Standing Order Frequently Asked Questions Anyone distributing under the standing order has to complete opioid overdose prevention and treatment training, and they are required to train the people they hand naloxone to. Qualified organizations can also apply to the Department of Health Care Services Naloxone Distribution Project to receive naloxone and fentanyl test strips shipped to them for free.3California Opioid Response. Naloxone Distribution Project
Beyond the organized channels, naloxone nasal spray is available over the counter at pharmacies and retailers without a prescription.
If You Use Naloxone on Someone
California Civil Code Section 1714.22 shields people who administer naloxone during an emergency. A non-licensed person who has completed overdose prevention training is protected from professional review, civil liability, and criminal prosecution as long as they act with reasonable care, in good faith, and without compensation. A separate provision gives broader civil immunity to anyone who administers naloxone in good faith and without compensation, regardless of training; that broader shield does not cover gross negligence or willful misconduct.4California Legislative Information. California Civil Code CIV 1714.22
The practical effect: if you use naloxone on someone you believe is overdosing, California law protects you from being sued or prosecuted for trying to save their life. The formal training requirement mostly matters for people distributing naloxone through organized programs, not for a bystander responding to an emergency in front of them.
The same statute also shields anyone who possesses or distributes naloxone under a prescription or standing order from professional review, civil suits, and criminal prosecution tied to that possession or distribution.5California Legislative Information.

Syringes: How to Get Them and Carry Them Legally
Two main paths put sterile syringes into people’s hands lawfully in California. Under Business and Professions Code Section 4145.5, a pharmacist or physician can furnish syringes without a prescription to anyone 18 or older for personal use. The buyer does not need a license or permit.6California Legislative Information. California Business and Professions Code 4145.5 The second path is through an authorized Syringe Services Program, which the law allows participants and providers to use without criminal exposure tied to their program participation.7California Legislative Information. California Health and Safety Code 121349
The paraphernalia picture is more complicated. Health and Safety Code Section 11364 generally makes it illegal to possess devices for injecting or smoking controlled substances. For years, the statute included an explicit exemption for personal-use possession of hypodermic needles and syringes, treated as a public health measure. That exemption carries a sunset date of January 1, 2026.8California Legislative Information. California Health and Safety Code HSC 11364 Whether the legislature extends it determines whether bare possession of a syringe outside the pharmacy or SSP context can be charged as a paraphernalia offense after that date.
Two things stay true regardless of what happens to the sunset. Syringes placed in a sharps container that meets state and federal disposal standards are always exempt from the paraphernalia law.8California Legislative Information. California Health and Safety Code HSC 11364 And providers participating in an authorized SSP remain shielded from criminal prosecution for needle possession tied to their program work.7California Legislative Information. California Health and Safety Code 121349
Fentanyl Test Strips
Fentanyl test strips are legal to possess and give out in California. Health and Safety Code Section 11364.5 excludes from the definition of drug paraphernalia any testing equipment designed or intended to test a substance for contaminants, toxic substances, hazardous compounds, or controlled substances, including fentanyl and its analogs.9California Legislative Information. California Health and Safety Code 11364.5 The same exemption reaches testing equipment for other adulterants, not only fentanyl. SSPs routinely distribute strips alongside sterile syringes, and the DHCS Naloxone Distribution Project ships them free to eligible organizations.3California Opioid Response. Naloxone Distribution Project
Syringe Services Programs
Syringe Services Programs are the main organized access point for sterile injection equipment and related services. Health and Safety Code Section 121349 authorizes them through two pathways.7California Legislative Information. California Health and Safety Code 121349 A local pathway requires action by a county board of supervisors and the local health officer, or by a city council and mayor. A state pathway lets organizations apply directly to CDPH’s Office of AIDS in areas where the department determines conditions favor the rapid spread of blood-borne disease. CDPH grants authorization for up to two years after consulting with local law enforcement and the local health officer, and can reauthorize at the end of each cycle.10California Department of Public Health.

Authorized programs typically offer more than clean syringes. Many provide wound care, HIV and hepatitis C testing, safer-use education, referrals to treatment and mental health services, naloxone, fentanyl test strips, and safer smoking supplies, delivered through fixed sites, mobile units, and street outreach.
Where Federal Law Pushes Back
State protections do not override federal law, and three friction points matter.
Federal drug paraphernalia law, 21 U.S.C. Section 863, bars selling or delivering paraphernalia but exempts anyone authorized by local, state, or federal law to manufacture, possess, or distribute such items.11Office of the Law Revision Counsel. 21 U.S. Code 863 – Drug Paraphernalia California’s authorization of SSPs and pharmacist syringe sales triggers that exemption, which is why these programs can operate without running afoul of federal paraphernalia rules.
Federal grant funding is more restrictive. The Consolidated Appropriations Act for fiscal year 2026 includes a provision (Section 525) that prohibits using federal appropriated funds to buy sterile needles or syringes for injection drug use. Funds can still support other parts of a syringe program if the state or local health department, in consultation with the CDC, determines the jurisdiction is experiencing or at risk for a significant increase in hepatitis infections or an HIV outbreak tied to injection drug use.12National Institutes of Health. Notice of Legislative Mandates in Effect for FY 2026 In practice, federal money can pay for staffing, training, and outreach but generally not for the syringes themselves.
Supervised consumption sites, where people use pre-obtained drugs under medical observation, are not legal in California and remain prohibited under federal law. 21 U.S.C. Section 856 makes it unlawful to manage or control any place and knowingly make it available for using a controlled substance.13Office of the Law Revision Counsel. 21 USC 856 – Maintaining Drug-Involved Premises California’s legislature passed SB 57 in 2022 to authorize pilot programs in several cities, but Governor Newsom vetoed the bill, and no later legislation has authorized these sites.14California Legislative Information.
