Hallucinogens are psychoactive substances that produce changes in perception, mood and cognitive processes. They affect all of the senses, altering a person’s thinking, sense of time and emotions. They can also cause a person to hallucinate—seeing or hearing things that do not exist or are distorted in nature.
