Subjective Effects

Physical

Spontaneous tactile sensations: The 'body high' of 4-HO-MiPT can be described as a pleasurable, warm, soft and all-encompassing tingling sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
Sedation: In terms of its effects on the physical energy levels of the tripper, 4-HO-MiPT is considered by most to be relaxing, stoning and mildly sedating. This sense of sedation is often accompanied by compulsive yawning.
Runny nose
Watery eyes

Cognitive

The cognitive effects of 4-HO-MiPT are described by many as extremely relaxing, profound and stoning in style when compared to other commonly used psychedelics such as LSD or 2C-B which tend to be energetic and stimulating.

Enhancement of current mind state
Connectivity of thought
Feelings of fascination, importance and awe
Time distortion
Outrospection
Déjà vu
Removal of cultural filter
Feelings of predeterminism
Conceptual thinking
Direct communication with the subconscious
Ego suppression, loss and death
Feelings of interdependent opposites
Delusions
States of unity and interconnectedness
Enhancement and suppression cycles: This can be described as constant waves of extremely stimulated and profound thinking which are spontaneously surpassed in a cyclic fashion by waves of general thought suppression and mental intoxication. These two states seem to switch between each other in a consistent loop once every 20 - 60 minutes.

Visual · Distortions

Visual drifting: (Melting, Flowing, Breathing and morphing) - In comparison to other psychedelics, this effect can be described as highly detailed, realistic, slow and smooth in motion and static in appearance.

Texture repetition
Colour shifting
Scenery slicing

Visual · Enhancements

Increased visual acuity
Enhancement of colour
Enhanced pattern recognition

Visual · Hallucinatory States

4-HO-MiPT and its various other forms produce a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics.

Transformations
Internal hallucinations: (Autonomous entities, Settings, sceneries, and landscapes, Alterations in perspective and Scenarios and plots) - This effect is very consistent in dark environments at appropriately high dosages. They can be comprehensively described through their variations as lucid in believability, interactive in style, new experiences in content, autonomous in controllability, geometry-based in style and almost exclusively of a religious, spiritual, mystical, science fiction or transcendental nature in their overall theme.

Toxicity

PsychonautWiki

The toxicity and long-term health effects of recreational 4-HO-MiPT use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 4-HO-MiPT is a research chemical with very little history of human usage. Anecdotal evidence from those have tried 4-HO-MiPT suggests that there are no negative health effects attributed to simply trying the drug by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption. It is strongly recommended that one use harm reduction practices when using this substance.
