<p dir="ltr">I just don't understand particularly why you would believe that besides cultural bias. Do you know what receptors psychedelics act on? Do you have evidence that the insights would be poorer than "sobriety"? Sobriety a diverse collection of mental states, and drugs add another state. What makes whatever mental state you were in, not on drugs, when you gained some insight, valid? Isn't the state of your brain right now a fairly stochastic phenomenon which may or may not produce valid insights? Sobriety is full of illusion too. I honestly suggest you go try some.</p>
<p dir="ltr">Another effect of psychoactive you CANNOT have without them is: being able to look at receptor affinities and compare effects. If one takes two drugs with different affinities for the 5HT1 or GABAB or CB2 receptor, then one can compare effects and gain insight on what it feels like to have sets of those particular receptors active. It is very valuable in neuroscience. And there's a long history of enthusiastic scientists using themselves as subjects.</p>
<p dir="ltr">I ought to stop self incriminating though. So, this is all theoretical. Or a joke. Or both.</p>
