All psychedelics are chemically unique and but can be catergorised into four main main types (see figure 2). There are three main families of chemical compounds: [[tryptamines]], phenethylamines, or lysergamides and many tend to act via serotonin 2A receptor agonism which plays a key role in regulation of cortical function. | All psychedelics are chemically unique and but can be catergorised into four main main types (see figure 2).

Serotonin antagonism has been proposed as the mechanism for the subjective and biological effects of classical psychedelics as these effects are blocked after administering 5HT2AR antagonists such as ketanserin<ref>Preller KH, Herdener M, Pokorny T, Planzer A, Kraehenmann R, Stämpfli P, et al.
