    What are the risks of mixing cocaine and mushrooms?

    Combining cocaine with psilocybin introduces cardiovascular, neurological and psychological risks. Cocaine can cause heart attacks, seizures and dangerous rhythm changes, while psilocybin can increase heart rate, blood pressure and distress. The combination is not a predictable way to balance either drug’s effects.

    Cocaine has serious acute risks on its own

    NIDA describes increased heart rate, blood pressure and temperature, as well as possible panic, paranoia, seizures, stroke and heart attack. Serious events can occur unexpectedly; a prior uneventful exposure does not establish safety. [1]

    Psilocybin adds altered perception and uncertainty

    Psilocybin can produce anxiety, confusion and cardiovascular changes. Available guidance does not establish a safe combined dose or a reliable sequence for using these drugs together. The magnitude of additional risk is not precisely quantified here. [2][3]

    Recognize emergency symptoms

    Chest pain, a seizure, collapse, marked confusion or breathing difficulty after this combination needs emergency assessment. Tell clinicians about all substances, including alcohol, prescribed medicines and any unknown products. [1][4]

    One drug does not neutralize another

    Imagine someone uses cocaine because mushrooms made them tired. Feeling more awake would not prove that perception, circulation or judgment are safe. Do not add further substances to counter the combination. [1][3]
