A psychedelic experience (known colloquially as a trip) is a temporary altered state of consciousness induced by the consumption of a psychedelic substance (most commonly LSD, mescaline, psilocybin mushrooms, or DMT).

In the context of travel and daily language, a "trip" is also known by several synonyms depending on the nature and duration of the journey. Common terms include "journey," which implies a longer, perhaps more significant movement from one place to another; "voyage," which typically refers to a long journey by sea or in space; and "excursion," which usually denotes a short, organized trip for pleasure or education. In a more professional or business setting, it might be called an "itinerary" (referring to the plan) or a "commute" (referring to a regular, repetitive trip). In informal or "slang" contexts, a trip can be called a "jaunt" or a "getaway." Interestingly, in a psychological or pharmacological context, a "trip" is also known as an "altered state of consciousness" or an "experience," specifically referring to the effects of certain substances. In mechanics and engineering, a "trip" can also refer to a "mechanical release" or a "triggering event" that activates a switch or safety mechanism. Ultimately, while "trip" is the most versatile and common term, its alternative names vary based on whether you are describing a vacation, a physical movement, or a mental state.
