Definition - What does Hallucinogen mean?

A hallucinogen is a classification of illegal drugs that cause the user to experience an altered sense of reality which can include hallucinations. A hallucinogen interferes with the brain's chemical balance and creates an alternate state of mind affecting thoughts, emotions, and perception of time. These drugs are usually either inhaled, ingested, or absorbed and their effects can last for up to 12 hours. They can be addictive. Hallucinogens are also known as psychedelics.

SureHire explains Hallucinogen

Many illicit drugs are hallucinogens. Examples of this type of drug include D-lysergic acid diethylamide (LSD), ketamine, ecstasy, and phencyclidine (PCP). A user might experience side effects such as nausea, tremors, high blood pressure, elevated body temperature, and heart rate. The drug alters mood, hunger and muscle control, and sometimes the experience elicits an unpleasant psychological reaction which is referred to as a bad trip. Severe effects of the drug include cardiac arrest, coma, and seizures. The possibility also exists that the drug effects persist beyond the drugs lifespan in the body, resulting in hallucinogen persisting perception disorder (HPPD).
