Disregard Everything I Say

These charts were found here and draw data from hundreds of studies on how hallucinogens like psilocybin and ketamine affect the brains of healthy people - as well as people suffering from depression and other disorders to produce various subjective experiences.  

This was done to show that the classical psychedelics such as Psilocybin (0.015–0.027 g per kg, by mouth) and dissociatives such as Ketamine (6–12 μg per kg per min, intravenously) produce a set of overlapping psychological experiences that can be measured.

In my opinion this is an excellent visual comparison of Psychedelics and Dissociatives. It was measured by using what is known as the “5DASC rating scale” which is described in detail here.
The scales indicate the percentage scored of the maximum score.
