But do you believe it because of the science or because you really really want to believe it? That's a serious question. I don't expect a ready answer.
I started with really wanting to believe it, and personal experiences have made it more mixed. I keep believing because of science, but the antiscientific attitude of some of the psychedelic community makes me wary about the future.
Your forgot to mention one more possible case: it is not science because of some political reasons.
Research was made impossible for 30 years but now there’s a thriving literature.
How much time and how many countries are there in your definition of "now"?
And how on Earth the Pihkal has been published exactly 30 years ago if the research was "impossible"?
