Who this is for: Anyone who has used or plans to use psychedelics and wants to understand what legal protections exist if something goes wrong — whether that means calling 911 for themselves, for someone else, or trying to get emergency help during a retreat or ceremony. Also for facilitators, retreat operators, therapists, and harm reduction workers who need to understand the legal environment in which they operate.

The short answer

Most states have overdose Good Samaritan laws that protect people who call 911 during a drug-related medical emergency from prosecution for simple possession of controlled substances. These laws were designed primarily for opioid overdoses but are broadly worded enough to apply to other drugs, including psychedelics, in most states. However, the protections are narrow, varied by state, and carry important limitations: they apply to state charges only, not federal; they do not protect against open warrants or parole and probation violations in most states; they do not cover distribution or trafficking; and awareness of the laws among both the public and law enforcement is inconsistent. The bottom line is that calling 911 during a psychedelic emergency is almost always the right decision and carries far less legal risk than most people fear — but the protections are not absolute, and knowing what they do and do not cover matters.

What Good Samaritan overdose laws are

Good Samaritan overdose laws — formally called 911 Good Samaritan Drug Overdose Laws or Fatal Overdose Prevention Laws — are state statutes designed to reduce drug overdose deaths by eliminating or reducing the fear of arrest that prevents bystanders from calling for emergency help. As of early 2026, 49 states and the District of Columbia have enacted at least one such law, according to the Network for Public Health Law’s survey of state laws. The two remaining states have narrower protections under other statutes, but no state has zero protection.

The core design is the same across jurisdictions: a person who in good faith calls for emergency medical assistance during a suspected drug overdose receives immunity or an affirmative defense against prosecution for certain drug-related offenses discovered as a result of that call. In most states, the person who overdosed also receives protection for the same offenses.

These laws emerged as a public health response to a documented pattern: fear of arrest was causing bystanders to delay or forgo calling 911, which resulted in preventable deaths. Research published in public health journals has found that Good Samaritan laws are associated with approximately a 15 percent reduction in opioid overdose mortality in states that have enacted them. In a GAO review of 17 studies, evidence consistently pointed toward lower overdose death rates in states with these laws compared to those without.

How they apply to psychedelics

Good Samaritan overdose laws were drafted primarily in response to the opioid epidemic and are written in terms of drug overdoses generally. Most statutes use language covering a person experiencing a suspected drug or alcohol overdose — not just opioids. This means the protection typically extends to someone having a dangerous reaction to psilocybin, MDMA, LSD, or another psychedelic, to the extent that reaction constitutes a medical emergency.

What the call protects against in most states is prosecution for simple possession of controlled substances. Psilocybin, MDMA, and other classical psychedelics are Schedule I controlled substances. A person who calls 911 because someone is having a severe adverse reaction to psilocybin — and who possesses psilocybin themselves — is, in most states, protected from prosecution for that possession under the Good Samaritan law.

The protection generally covers both the caller and the person experiencing the emergency.

What Good Samaritan laws do not cover

The limits of these protections are as important as the protections themselves.

Federal law. Good Samaritan overdose laws are state statutes. They apply to state criminal charges only. Every state that has one says so explicitly — Maryland’s statute, for example, states directly that “it is a state law and only applies to State crimes, not Federal or immigration laws.” A federal prosecution for possession, manufacture, or distribution of a Schedule I substance is entirely unaffected by a state Good Samaritan law.

Outstanding warrants. Virtually every state’s Good Samaritan law excludes protection from arrest or prosecution on outstanding warrants. A person with an active arrest warrant who calls 911 during a psychedelic emergency may still be arrested on that warrant when police arrive.

Parole and probation violations. Most state laws do not protect against parole or probation violations. In states that do extend protection — some explicitly provide that a good faith call to 911 will not result in a probation or parole violation — the protection is narrower than it sounds: evidence obtained solely because of the emergency call cannot be used as the basis for the violation, but evidence independently known to probation or parole authorities remains available.

Distribution and trafficking. Good Samaritan protections cover possession, not distribution. A person who supplied the drugs that caused the overdose or emergency — or who possessed quantities that suggest distribution rather than personal use — is generally not protected. Washington state’s statute makes this explicit: the protection does not cover drug manufacture or delivery, or controlled substances homicide.

Other crimes. Protection covers specified drug offenses only. Other crimes discovered when emergency responders arrive — weapons, unrelated contraband, other illegal activity visible at the scene — are not protected by the overdose Good Samaritan law.

Retreat and ceremony operators. Someone running a commercial psychedelic ceremony who calls 911 when a participant has a medical emergency may be protected from simple possession charges under the Good Samaritan law. They are not protected from charges related to distribution, operation of an unlicensed drug program, or other offenses arising from the commercial facilitation context.

The awareness problem

A New York-based study found that individuals with accurate knowledge of Good Samaritan laws were three times more likely to call 911 during an overdose compared to individuals with inaccurate knowledge. The GAO’s review of studies consistently found that awareness of these laws varies substantially across jurisdictions among both law enforcement and the public. People who do not know the law exists cannot rely on its protections.

Even where the law is known, implementation is inconsistent. Some police departments have adapted their practices to honor the spirit of the law, deprioritizing arrest when they arrive at an overdose scene. Others have continued making arrests for charges beyond what the law covers — sometimes for charges the law does not actually protect against, and sometimes erroneously for charges it does protect against. The legal protection exists on paper; its application in practice depends on the officer and the jurisdiction.

The implication for psychedelic users and facilitators is twofold: know the Good Samaritan law in your specific state before you need it, and call 911 when someone’s safety is at risk regardless of the legal uncertainty. The legal risk of calling is far lower than the medical risk of not calling during an emergency.

What happens when you call 911

When 911 is called during a psychedelic emergency, paramedics and police typically both respond. Paramedics focus on medical stabilization. Police may assess the scene for other crimes or potential charges beyond what the Good Samaritan law covers. What specifically happens depends on the jurisdiction, the officers who respond, the scale of what they observe, and whether there are other circumstances — warrants, probation, quantities suggesting distribution — that fall outside the law’s protection.

For most people in most situations: if the emergency is genuine, the amounts involved are consistent with personal use, there are no outstanding warrants or active supervision conditions, and no commercial facilitation is involved, the Good Samaritan law in most states covers the drug possession charge that would otherwise arise from the call.

The practical guidance from harm reduction organizations is consistent: if someone is in genuine medical danger, call 911. The protection exists. The alternative — not calling — produces far more certain and far more severe harm.

Harm reduction practices and their legal status

Harm reduction describes a range of practices designed to reduce the risks associated with drug use without requiring abstinence. For psychedelics specifically, harm reduction typically includes:

Substance testing. Testing psychedelics for adulterants — including fentanyl, which has been found in samples sold as MDMA — is a legal activity in most states. Fentanyl test strips are now widely available and legal in the vast majority of states following legislative changes in response to the opioid epidemic. Reagent test kits for identifying other substances are also legal to purchase and use. Possessing these items is not a crime. Possessing the substances being tested remains whatever it is under the applicable law.

Harm reduction spaces and festivals. Organizations operating drug checking services, trip sitting, or crisis support at events exist in a legal gray zone in most states. They typically do not themselves possess controlled substances, so the primary legal risk they navigate involves licensing, health department requirements, and the extent to which their activities might be characterized as facilitating or enabling drug use. The legal analysis depends heavily on state law and the specific activities involved.

Trip sitting. Being present and supportive with someone who is having a psychedelic experience — without possessing the substance yourself — is not itself a criminal act in most jurisdictions. A therapist or counselor who provides integration support for psychedelic experiences is engaged in a professional practice that is legal, though they should be careful not to cross into advising on or facilitating the acquisition or use of the substance itself.

Common mistakes and misconceptions

“Good Samaritan laws fully protect me if I call 911.” They protect against specific state drug possession charges. They do not protect against federal charges, warrants, parole violations, distribution charges, or other offenses.

“I can’t call 911 because we had psychedelics and we’ll all get arrested.” In the vast majority of states, the person calling and the person experiencing the emergency are both protected from simple possession charges if the call is made in good faith. The risk of not calling in a genuine emergency far exceeds the legal risk of calling in most situations.

“The Good Samaritan law is the same everywhere.” It is not. The specific offenses covered, the threshold amounts protected, whether probation and parole are protected, and how police implement the law vary substantially by state. Know the law in your state.

“I can rely on Good Samaritan protection to run a psychedelic ceremony commercially.” Good Samaritan protections cover possession, not the commercial facilitation of drug use. The legal risks of operating an unlicensed psychedelic ceremony are not addressed by overdose protection laws.
