Synaesthesia (also spelled synesthesia or synæsthesia) is the experience of a blending, merging, or mixing of the senses. [1] For example, a person experiencing synaesthesia may begin seeing music, tasting colors, hearing smells, or any other potential combination of the senses. [2] At its highest level, synaesthesia becomes so all-encompassing that each of the senses become completely intertwined with the rest of one's senses. This is a complete blending of human perception and is usually interpreted as extremely profound when experienced. It is worth noting that a significant percentage of the population experience synaesthesia to varying extents during everyday life without the use of drugs. [3] [4]

Synaesthesia is commonly induced under the influence of heavy dosages of psychedelic compounds, [5] such as LSD, psilocybin, and mescaline. However, it is seemingly most commonly experienced under the influence of stimulating psychedelics such as the 2C-x, DOx, and Nbome series.
