Gustatory depression

Gustatory depression is the experience of tastes becoming significantly vaguer, weaker, and less noticeable than that of everyday sobriety. At higher levels, this can result in food becoming completely tasteless and significantly less appealing.

Gustatory depression is often accompanied by other coinciding effects such as tactile suppression and pain relief. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as ketamine, PCP, and DXM. However, it can also occur under the influence of depressants such as opioids and antipsychotics.
