• Gustatory enhancement

  Gustatory enhancement is the experience of tastes becoming significantly richer, stronger, and more noticeable than that of everyday sobriety. 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 cannabinoids and stimulants

• Gustatory hallucination

  A gustatory hallucination is any hallucination that involves one's sense of taste. A common example of this is a strong, unpleasant metallic taste in one's mouth. They are most commonly induced under the influence of moderate dosages of hallucinogenic compounds, such as psychedelics, dissociatives, and deliriants.

• Gustatory suppression

  Gustatory suppression is the experience of tastes becoming significantly vaguer, weaker, and less noticeable than they would be during everyday sobriety. At higher levels, this can result in food becoming completely tasteless and significantly less appealing. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as ketamine, PCP, and DXM.

• Olfactory enhancement

  Olfactory enhancement (also known as hyperosmia) is the experience of smells becoming significantly richer, stronger, and more noticeable than they would be during everyday sobriety. This experience can either be positive or negative depending on the smell and the person's prior opinion of them. For example, while certain smells such as food or flowers may become a true delight during this experience, other smells such as pollution or body odour may become overpoweringly uncomfortable, which can potentially trigger nausea and vomiting.

• Olfactory hallucination

  An olfactory hallucination (also known as phantosmia) is the detection or perception of a convincing imaginary smell that is not actually present in the person's environment. They are most commonly induced under the influence of heavy dosages of hallucinogenic compounds, such as deliriants and psychedelics.

• Olfactory suppression

  Olfactory suppression (also known as anosmia) is the experience of smells becoming significantly vaguer, weaker, and less noticeable than they would be during everyday sobriety. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as ketamine, PCP, and DXM.
