Scenery slicing + Efavirenz
Efavirenz is known to produce scenery slicing, a visual effect. The visual field fractures into distinct, cleanly cut sections that slowly drift apart from their original positions before resetting, as if reality has been sliced by an invisible blade into geometric pieces that briefly separate and rearrange.
About Scenery slicing
Scenery slicing is a visual distortion in which a person's visual field appears to split into separate, cleanly cut sections, as if the entire scene has been divided by invisible blades into distinct pieces. These individual slices then proceed to drift slowly away from their original positions — sliding, rotating, or separating along their cut lines — before eventually disappearing and resetting to normalcy. The effect is remarkably crisp and precise, with the divisions appearing as sharp, well-defined edges rather than blurry or gradual transitions.
This effect typically occurs spontaneously and rarely sustains itself for more than several seconds before the visual field reassembles and returns to its normal, continuous appearance. However, it frequently recurs throughout the experience, with each episode potentially displaying a different pattern of cuts and movements. The momentary nature of the effect gives it a startling quality, as the visual world seems to briefly shatter and reform like a living puzzle.
The organization and complexity of the slices can vary enormously. At their simplest, they may consist of just two or three large sections — a horizontal or diagonal cut dividing the visual field into halves or thirds. At their most complex, the slices can form elaborate geometric arrangements involving dozens of interlocking pieces arranged in spiraling, tiling, or radially symmetrical configurations. Some users report seeing their visual field divided into moving interlocking spirals, rotating pie-slice segments, venetian-blind-like horizontal strips, or an infinite variety of other potential geometric formations.
Scenery slicing is most commonly induced under the influence of moderate to heavy dosages of dissociative compounds such as ketamine, PCP, DXM, and methoxetamine. With dissociatives, the effect tends to be more pronounced and features cleaner, more angular cuts that align with the blocky, fragmented quality of dissociative visual effects in general. However, scenery slicing can also occur under the influence of psychedelics such as LSD, psilocybin, and mescaline, where it tends to appear in more fluid, organically curving forms.
Subjective reports frequently compare this effect to a scene from a film that has been literally cut apart with scissors and rearranged, or to a reflection in a shattered mirror where each shard shows a slightly displaced version of the same image. Users often note the uncanny precision of the cuts, describing them as impossibly clean and geometric in a way that feels more digital than organic. The effect can produce feelings of fascination, mild disorientation, or amusement depending on its intensity.
Scenery slicing is often accompanied by other coinciding visual effects such as environmental cubism, visual disconnection, and depth perception distortions. When multiple visual distortions co-occur, the fragmented, sliced quality of this effect can combine with drifting, recursion, or geometric patterns to produce extraordinarily complex visual scenes in which the environment seems to be simultaneously fracturing and reforming in kaleidoscopic fashion.
