A bad trip is a negative experience that can occur after taking a psychoactive or hallucinogenic drug. During a bad trip, the intensity of the high can become extremely frightening or overwhelming, and the person may experience hallucinations, paranoia, and intense anxiety. Symptoms of a bad trip are highly individualized and may include elevated heart rate, nausea, tremors, intense feelings of anxiety and depression, hallucinations, and altered perceptions. Bad trips can be exacerbated by the inexperience or irresponsibility of the user or the lack of proper preparation and environment for the trip. Some of the things that can increase the probability of a bad trip include the setting, the amount of the drug taken, and the users psychological state. While it may not always be possible to stop a bad trip, there are things that can be done to help someone who is having a bad trip, such as moving them to a safe space, providing a positive and supportive environment, and seeking emergency intervention if necessary. It is important to note that bad trips are not always negative experiences and can sometimes lead to deep existential and life-altering insights.
