The phrase "mind-expanding drug" is often used to describe substances that alter perception, cognition, and consciousness. However, there are many other phrases that can be used to describe these types of drugs. "Psychedelic substance" is a common alternative, as is "hallucinogen," "entheogen," or "visionary plant medicine." Other phrases might be more specific to particular substances or traditions, such as "ayahuasca" or "iboga." Ultimately, the choice of phrase will depend on the context in which the drug is being discussed, as well as the speaker or writer's particular views on drug use and their cultural and personal background.
