For all these reasons, one must be cautious in interpreting these initial results... The movie used for the survey as well as a results summary can be found online at Solving the mystery of the origins of the trailing effect might reveal something deep about the mechanisms underlying

Mentions: Ask any LSD user: they know the drug is taking effect when the “goodtrails” kick in. Trailing is a visual perceptual effect commonly experiencedduring LSD consumption and as a long-lasting side effect of the drug (hallucinogenpersisting perception disorder) [1]–[4]. LSD users perceive a series of discrete positiveafterimages in the wake of moving objects, a percept that has been likened to amultiple-exposure stroboscopic photograph, somewhat akin to Etienne-JulesMarey's chronophotographs [5] from 1880, or to more recent digital art produced in a fewclicks (Figure 1).
