Candy flipping is a colloquial term, or drug slang, which refers to the psychoactive experience of combining LSD and MDMA. These two chemicals have been used separately in past psychoanalytical and psychotherapeutic experiments and even treatment. Together, these substances are alleged to allow the user to reach a psychological state in which they feel able to freely and critically analyze their emotions, personal belief systems, relationships (especially with any others who may be present) et cetera. However, candy flipping often tends to be a purely recreational event.
