Reviewed for accuracy by licensed clinical professionals.

Music festivals and concerts are environments where drug use is common and risks are elevated by heat, dehydration, physical exertion, and distance from medical care. This guide prioritizes keeping people alive.

Common substances and risks

MDMA/molly: hyperthermia, dehydration, and water intoxication are the primary risks in festival settings. Cocaine: cardiovascular stress amplified by heat and exertion. Psychedelics: bad trips in overwhelming sensory environments. Ketamine: loss of coordination leading to falls and injury. Fentanyl: present in counterfeit pills and contaminating other substances.

Harm reduction at events

Test your substances (fentanyl test strips, drug checking services where available). Never use alone. Start with small doses. Stay hydrated (but do not overhydrate with MDMA). Take breaks from heat and exertion. Know where medical services are located. Carry naloxone.

Emergency signs

Unresponsiveness, stopped breathing, blue lips, seizures, extremely high body temperature, or chest pain all require immediate medical attention. Do not wait. Medical staff at festivals will not report you to police (Good Samaritan protections apply).

The honest truth

The safest choice is not using substances at events. But if harm reduction keeps someone alive until they are ready for recovery, it has served its purpose.
