A lot of people believe they found *the* objective truth while high, and because of that they turn arrogant afterward toward experiences/thoughts of others.
I've had friends who started acting like that, I once did myself, believing that they had found the one truth other people hadn't found, but since my friend group is generally honest and real with each other, we've helped them down from their arrogance.
However, I think it can be hard for people like CEOs, surrounded by sycophantic bootlickers, to realize that. They'll quickly be convinced by their own hubris.
"drugs" are an extension of "food" and "breathing" .. what ? everyone agrees that you have to eat, and people do.. yet the details of eating, and what you eat, are massively varied.. too varied to make meaningful generalizations on a text forum. Similarly, when you ingest "stuff" there are complicated interactions that happen without consciously knowing it.. the edge of those interactions are what you are calling "drugs"
Lastly, some of the old herbal drugs were awful, and we are evolving past those.. but, some of the new synthesized drugs are more awful.. some of them are being used by millions right now.
