Everyone reacts differently to hallucinogens.
Effects depend upon the user's personality, mood, expectations, and surroundings.
Depending on the dose, the drug can produce delusions and visual hallucinations. Users experience distorted senses of direction, distance, and time. Hallucinogens can produce unpredictable, erratic, and violent behavior. During a bad trip, terrifying thoughts and feelings, fear of insanity and death, injuries, and fatal accidents can occur. Physical effects include dilated pupils, higher body temperature, increased heart rate and blood pressure, sweating, loss of appetite, sleeplessness, dry mouth, and tremors.
