“I used to believe such things 30 years ago.
Cary Mullis, who invented the polymerase chain reaction and deseverdly won the Nobel Prize for it, said the idea came to him under the influence of LSD.”
Why did you ‘used to’ believe if you are aware of numerous real examples?
Because the ideas would come anyhow and probably with more regularity and clarity.
And for the sake of argument accepting some examples, they are rare and not representative by a long shot of the actual short term and long term effects.
