Some ppl prefer to combine E with LSD (known as candy-flip in the USA) or with psilocybin mushrooms, thus combining hallucinogenic qualities to the warmth of Ecstasy. This also extends the experience at low cost, as LSD lasts for about twice as long as MDMA. Home users often use this combination, particularly in natural surroundings.
Home users refer to MDMA as a psychedelic amplifier or catalyst, enhancing the effect of psychedelics without changing their quality, although others experience that LSD loses its usual effect and simply amplifies the effect of the Ecstasy. Another use for Ecstasy is to avoid bad trips: once a positive mood is established by Ecstasy, the course is set for the LSD trip.
