Stimulate the sympathic nervous system -Causing rise in blood pressure and pulse rate -Can trigger sweating, palpitations or nausea -Interferes with dopamine, norepinephrine, acetylcholine, anandamine, alpha psychoism, and especially serotonin -Stimulation of brain stem causes overload on sensory pathways making user acutely aware of all sensation -Disruption of visual and audio centers can confuse perception

Physical and mental effects of hallucinations
