- Stimulation – This compound produces stimulating effects at lower doses which are less intense than that of diphenidine or methoxphenidine.
- Tactile disconnection
- Spatial disorientation
- Pain relief
- Cough suppression
- Appetite suppression
- Nausea – This effect is inconsistently produced even within similar dosage ranges.
- Changes in felt gravity
- Spontaneous physical sensations – The ephenidine “body high” is a soft and pleasurable tingling sensation which is motionless and all-encompassing with no specific location.
- Tactile suppression – This partially to entirely suppresses one’s sense of touch, creating feelings of numbness within the extremities. It is responsible for the anaesthetic properties of this substance.
- Motor control loss – A loss of gross and fine motor control alongside of balance and coordination is prevalent within the ephenidine experience and becomes especially strong at higher doses. This means that one should be sitting down before the onset (unless one is experienced) in case of falling over and injuring oneself.
- Perception of bodily lightness – This creates the sensation that the body is floating and has become entirely weightless. This effect is strangely stimulating and encourages physical activities at low to moderate doses by making the body feel light and effortless to move.
- Gait alteration – Ephenidine typically causes movement such as walking to be perceived as automated and robotic.
- Physical autonomy
- Increased heart rate
- Orgasm suppression
- The general head space of ephenidine is often described as particularly euphoric and clear-headed in comparison to that of DXM and ketamine. The specific cognitive effects can be broken down into several separate subcomponents which are listed and described below:
- Thought acceleration and deceleration
- Dream potentiation
- Consciousness disconnection
- Memory suppression
- Ego death – This occurs at high dosage.
- Ego inflation – This occurs at low dosage and in a fashion that is less intense to that of mephedrone, methamphetamine or cocaine.
- Motivation enhancement – This occurs at low dosage.
- Analysis suppression
- Time distortion – This creates the illusion of time passing much more slowly than it would while sober. For example, a user could perceive that an hour or several hours have passed, over the course of only a few minutes.
- Cognitive euphoria
- Novelty enhancement
- Creativity enhancement
- Déjà vu
- Conceptual thinking
- Compulsive redosing
- Anxiety suppression
- Increased music appreciation
- Personal meaning enhancement
- Decreased libido
- Visual disconnection – This eventually results in the ephenidine equivalent of the famous “k-hole” or, more specifically, holes, spaces and voids alongside of structures. However, it is worth noting that particularly heavy doses must be consumed to reach the deepest state of this component in comparison to other more classical dissociatives such as ketamine or methoxetamine.
- Visual acuity suppression
- Double vision – This component is prevalent at moderate to heavy dosages and makes reading impossible unless one closes an eye.
- Pattern recognition suppression – This effect generally occurs at higher dosages and makes one unable to recognize and interpret perceivable visual data.
- Frame rate suppression
- Drifting (melting, flowing, breathing and morphing) – In comparison to other dissociatives, this effect is more prominent than ketamine, MXE, diphenidine and methoxphenidine. The visual drifting is simplistic, slow and smooth in motion, static in appearance and unrealistic/cartoon-like in style.
- Perspective distortions
- Environmental orbism
- Environmental cubism
- Scenery slicing
- Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) – In comparison to other dissociatives, this effect can occur at heavy dosages, but is considerably less common than the same effect found within psychedelics and deliriants. It can be comprehensively described through its variations as delirious in believability, fixed in style, equal in new experiences and memory replays in content, autonomous in controllability and solid in style.
