English: VERY IMPORTANT TO NOTE WHEN VIEWING THIS GRAPH:

Ki Values are reported in such a way that the lower the number is, the higher affinity the structure has for the receptor. This means that the LOW values on the graph are the relevant information NOT the taller bars.

I created this file from public source data (http://pdsp.cwru.edu/pdsp.php). The black horizontal line represents the plasma level of LSD in humans during recreational use (Aghajanian & Bing, (1964) Clin. Pharmacol. Ther. 5, 611-614) and hence receptors which LSD has an affinity for above the line are unlikely to be affected by recreational LSD doses.
