Physical enhancements can be defined as any effect which intensifies or enhances a facet of one's physical body.

This page lists and describes the various physical enhancements which can occur under the influence of certain psychoactive compounds such as psychedelics.

Appetite enhancement

Main article: Appetite enhancement

Appetite enhancement can be described as the simple experience of increased hunger, appetite and an enhancement of one's own sense of taste. This effect occurs on certain substances such as mirtazapine and cannabis and is often referred to colloquially as "the munchies."

Bodily control enhancement

Bodily control enhancement can be described as an effect which induces a dramatic increase in a person's control over their physical body. This results in the ability to accurately control a greater variety of muscles across one's body with the tiniest of precise mental triggers.

It is often interpreted by people as a profound and primal feeling of being put back in touch with the animal body.

Perception of bodily heaviness

Perception of bodily heaviness can be described as feelings of the body becoming extremely heavy. This can result in one's body feeling as if it is difficult, uncomfortable, or sometimes impossible to move, resulting in feelings of slowness and sluggishness. This effect indirectly encourages feelings of sedation by making it uncomfortable or difficult to move.


Main article: Stimulation

Stimulation can be defined as any changes in a person's energy levels which are interpreted as encouraging when it comes to movement and physical activities such as running, walking, cleaning, socializing, dancing, and climbing.


Physical stimulation can be broken into two basic forms:

  • Forced stimulation - This can be described as the effects of increased energy becoming so pronounced that (at higher dosages) the user will experience uncontrollable physical shaking, jaw clenching and tremors should they choose to ignore the stimulation and remain still.
  • Encouraged stimulation - This can be described as feeling extremely energetic but in a purely controllable fashion that does not overwhelm the user with involuntary movements should they choose to stop expending large amounts of energy.

Tactile enhancement

Main article: Tactile enhancement

Tactile enhancement can be described as an overall increase in both the intensity of a person's sense of touch and their awareness of the physical sensations across their body. At its highest level, this becomes extreme enough that the exact location and current sensation of every single nerve ending across one's skin can be felt and comprehended all at once. In contrast, throughout normal sober living, most people can only maintain awareness of the tactile sensations which are relevant to their current situation.

This effect can result in tactile sensations such as touching, hugging, kissing, and sex becoming greatly enhanced in terms of the pleasure they induce. However, it can also result in an over-sensitivity of the skin which causes the same sensations to become uncomfortable and overwhelming.

Tactile enhancement is often accompanied by other coinciding effects such as spontaneous tactile sensations and physical euphoria. It is most commonly induced under the influence of moderate dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline. However, it can also occur under the influence of stimulants, cannabinoids, and certain dissociatives.

Stamina enhancement

Main article: Stamina enhancement

Stamina enhancement can be described as an increase in one's ability to engage in physically and mentally taxing activities without the development of fatigue. Although this effect is commonly mistaken for stimulation, it differs as it is not a direct increase in one's energy levels. Instead, it is an increase in one's resilience in performing an activity and a mitigation of general fatigue.

Psychoactive substances that directly increase one's endurance without stimulation are known as actoprotectors. These are are defined as "substances that enhance body stability against physical or mental loads without increasing oxygen consumption or heat production."[1]
