Dose Response for Psilocybin

I took some of the data from the paper "Psilocybin occasioned mystical-type experiences: immediate and persisting dose-related effects" and put it into a spreadsheet to get some graphs.  A lot of the effects were surprisingly linear.  I normalized the data so that the 5mg amount for all effects was 1.0.  Overall I find the second graph more interesting in terms of effects measured and the fact that there was an acceleration from 10mg to 20mg, perhaps similar to going from 1.7 to 3.3 grams of dried mushrooms.
