Slang term for the simultaneous use of
LSD ("acid") and
MDMA ("Ecstasy").
It is generally preferable to have experience with both of these drugs on their own before trying them together, lest the experience be too overwhelming. Given that, candyflippers often feel they are getting "the best of both worlds" by combining the pleasure and confidence of rolling with the intellectual and visual stimulation of tripping.
There have been no formal studies conducted which demonstrate any special negative reaction between these two chemicals. However, the risks inherent for each of them remain, and any potential candyflipper would do well to keep this in mind.
