LSZ Effects

Bodily control enhancement is the subjective feeling of improved physical precision, coordination, and dexterity — a sense of heightened mastery over one's own body that can make movements feel fluid, deliberate, and effortless.

An uncomfortable sensation of queasiness and stomach discomfort that may or may not lead to vomiting, often occurring during the onset phase of many substances.

A visible enlargement of the pupil diameter (mydriasis) that can range from subtle widening to dramatic saucer-like expansion where the dark pupil dominates the iris. This effect is one of the most recognizable signs of psychedelic and stimulant intoxication and directly contributes to light sensitivity, enhanced color perception, and the characteristic "wide-eyed" appearance.

Uncontrolled brain electrical activity causing convulsions and loss of consciousness -- a life-threatening medical emergency requiring immediate help.

A state of heightened physical and mental energy characterized by increased wakefulness, elevated motivation, and a subjective sense of vigor that pervades both body and mind. Users often report feeling electrically alive, with a buzzing readiness to move, talk, and engage that can range from a pleasant caffeine-like lift to an overwhelming, jittery compulsion to act.

The sense of touch becomes dramatically heightened, making physical contact feel intensely pleasurable and detailed. Textures and skin contact produce amplified richness.

An intensification of the brightness, vividness, and saturation of colors in the external environment, making the world appear dramatically more colorful. Reds seem redder, greens seem greener, and all hues appear richer and more distinct than during ordinary perception.

The visual experience of colors on objects and surfaces cycling through continuous, fluid transformations, shifting from one hue to another in smooth, seamless loops. A green surface might flow through blue, purple, red, and back to green in a mesmerizing animated sequence.

Alterations in how the distance of objects within the visual field is perceived, causing layers of scenery to appear exaggerated, rearranged, flattened, or warped in spatial depth.

The visual experience of perceiving stationary objects, textures, and surfaces as appearing to flow, breathe, melt, or shift in position. Drifting is one of the most fundamental and commonly reported visual distortions under the influence of psychedelic substances, serving as the perceptual foundation upon which many other visual effects are built. It manifests as a fluid, organic sense of motion embedded in otherwise static visual fields.

The experience of perceiving complex, ever-shifting geometric patterns superimposed over the visual field or visible behind closed eyelids. Geometry is widely considered the hallmark visual effect of psychedelic substances, ranging from simple lattice patterns and honeycombs at low doses to infinitely complex, self-transforming fractal structures at high doses that can feel profoundly meaningful and awe-inspiring.

Vivid, detailed visual experiences perceived within an imagined mental landscape that can only be seen with closed eyes, ranging from fleeting imagery and abstract scenes to fully immersive, dream-like environments with autonomous narratives and entities.

An increased ability and tendency to perceive meaningful patterns, faces, and images within ambiguous or random visual stimuli such as textures, clouds, and surfaces.

Distortion of perceived depth, distance, and size of real objects, making things appear closer, further, larger, or smaller than they actually are.

A hallucinatory phenomenon in which the observer's visual perspective shifts from the normal first-person viewpoint to alternative vantage points — including third-person (seeing oneself from outside), bird's-eye, or omniscient perspectives — during both internal and external hallucinations.

The perceived environment in which hallucinatory experiences take place, ranging from recognizable locations drawn from memory to entirely novel alien landscapes, ancient civilizations, cosmic vistas, and impossible architectural spaces.

Textures appear to mirror and tessellate across surfaces in intricate, self-similar symmetrical patterns that maintain detail at every scale. Most prominent in peripheral vision on rough surfaces.

Moving objects leave visible trails of varying length and opacity behind them, similar to long-exposure photography. Trails may match the object color or appear in other hues.

Objects and scenery undergo perceived visual metamorphosis, smoothly shapeshifting into other recognizable forms over seconds. Patterns morph into faces, animals, and imagery.

Vision becomes sharper and more defined than normal, as though a slightly blurry lens has been brought into perfect focus. Edges appear crisp and fine details become vivid.

A perceived improvement in one's ability to logically deconstruct concepts, recognize patterns, and reach novel conclusions, often accompanied by deep states of contemplation and an abundance of insightful ideas.

Intense feelings of apprehension, worry, and dread that can range from a subtle background unease to overwhelming panic attacks with a sense of impending doom, often amplified by the substance's intensification of one's existing mental state.

A shift in the nature of thought from verbal, linear sentence structures to intuitive, non-linguistic concepts that are felt and understood rather than spoken by an internal narrator.

An increase in the ability to imagine new ideas, overcome creative blocks, think about existing concepts in novel ways, and produce artistic or intellectual work with greater fluency and inspiration.

A delusion is a fixed, false belief that is held with unshakeable certainty and is impervious to contradicting evidence or rational argument — often involving grandiose, persecutory, or bizarre themes that are clearly at odds with observable reality.

A heightened capacity to become fully absorbed and engrossed in external media such as music, films, video games, and art, with an amplified suspension of disbelief and a deepened emotional connection to the content being experienced.

An enhanced state of self-reflective awareness in which one feels drawn to examine their own thoughts, emotions, behaviors, and life patterns with unusual depth, clarity, and emotional honesty, often yielding insights that feel therapeutically significant.

Abnormally elevated mood, energy, and activity with impulsive behavior and grandiosity, associated with stimulant use and certain drug interactions.

A dose-dependent inhibition of one's ability to access and utilize short-term and long-term memory, ranging from mild forgetfulness to a profound inability to recall personal identity, biographical information, or the context of the current experience.

Mindfulness in the substance context refers to a state of heightened present-moment awareness in which attention is fully directed toward immediate experience — thoughts, sensations, emotions — with an attitude of non-judgmental observation, while the usual stream of planning, worrying, and self-referential thinking quiets substantially.

A feeling of increased fascination, awe, and childlike wonder attributed to everyday concepts, objects, and experiences, as if perceiving the world for the first time.

A panic attack is a discrete episode of acute, overwhelming fear or terror that arises suddenly and peaks within minutes, accompanied by distressing physical symptoms including rapid heartbeat, shortness of breath, chest tightness, trembling, dizziness, and a profound sense that one is dying, going insane, or losing control.

Irrational suspicion and belief that others are watching, plotting against, or intending harm toward oneself, ranging from mild unease to overwhelming terror.

A decrease in the personal, cultural, and cognitive biases through which one normally filters their perception, enabling more objective self-examination and worldview analysis.

Psychosis is a serious psychiatric state involving a fundamental break from consensus reality — characterized by firmly held false beliefs (delusions), perception of things that are not there (hallucinations), disorganized thought and speech, and a loss of the ability to distinguish internal mental events from external reality.

The experience of thoughts occurring at a dramatically increased rate, as if the mind has been shifted into a higher gear. Ideas, associations, and internal dialogue cascade rapidly, often outpacing the ability to articulate or fully process each one, producing a subjective sense of heightened mental velocity.

Thought disorganization is a cognitive impairment in which the normal capacity for structured, sequential, and logical thinking becomes significantly disrupted, causing thoughts to become scattered, tangential, and difficult to follow to completion.

Becoming trapped in a repeating cycle of thoughts, actions, and emotions that loops every few seconds to minutes. Short-term memory lapses cause the sequence to restart.

Subjective perception of time becomes dramatically altered — minutes may feel like hours, or hours pass in moments. Can manifest as either dilation or compression.

An increased ability to stay awake and alert without the desire to sleep. Distinct from stimulation in that it does not elevate energy above a naturally rested baseline.

Scenarios and plots are the narrative structures that emerge within hallucinatory states — coherent or surreal storylines involving autonomous characters, unfolding events, and immersive settings that can feel as real and consequential as waking life.

A profound dissolution of the sense of self in which personal identity, memories, and the boundary between self and world completely vanish, leaving only pure undifferentiated awareness.

A profound intensification of spiritual feelings, mystical awareness, and a sense of sacred connection to something greater than oneself. This can range from a subtle sense of cosmic significance to full-blown mystical experiences indistinguishable from those described in religious traditions.

A profound sense that identity extends beyond the self to encompass other people, nature, or all of existence. Boundaries between self and other dissolve into felt oneness.
