At the higher doses, psilocybin can cause severe distortion in all body sensations and thinking. This can include abnormal perception in all senses such as visual changes, visual hallucinations, hearing changes and auditory hallucinations, abnormal smells or bodily sensation, and an unusual mixing of sensations where for example sounds may be perceived as pictures or images or colors could be perceived as tastes. These experiences are usually accompanied by intense changes in mood states. This can include elation or euphoria, anxiety and panic feelings, or depressive feelings.
Emotions can change quickly from one to another.
While these experiences are described by most people as pleasant or profound, to some it may be frightening and include symptoms of panic, depression, and confusion. The symptoms listed above usually begin within the first hour after taking the psilocybin and can last for up to 12 hours, although most people find that these symptoms are gone by 6 hours after ingestion. Psilocybin can also cause dizziness, nausea, vomiting, headaches, increased pulse and blood pressure, dilated pupils, slightly elevated temperature, raising of skin-hair, and increased reflexes. These symptoms usually can begin 20 to 30 minutes after taking the drug and can last up to 6 hours. It is not known how often this really occurs.
