> I am wondering why anyone would think they are in an adequate position to write anything about a topic, even though they neither did proper research whatsoever on the topic nor have their own experiences in the matter.

I think everyone is in a position to write a post about why they themselves don't do something. It's his blog - he's a fairly well-known person who a lot of people are interested in, I'm sure he's been asked before about this topic, and he chose to answer it, on his personal blog. Who would be better positioned than him to say why he chooses to do (or not do) something?

He's not saying using psychedelics is wrong or that other people should or shouldn't use them, he's saying why he chooses not to use them.

Literally the first line is:

"I am not sure how many people should use psychedelics, and I do not wish anything in this post to be construed as advice."
