Nice strawman you got there. Meth is a man made synthetic compound. Fungi cover this earth and are one of the few natural drugs that cause brain elasticity and can cause personality change.

The theory is real and, of course, controversial[0]. The formation of consciousness is still a mystery and I’m simply discussing a theory. If you have another theory you deem right, let’s argue on merit, not personal attacks.

A theory can be "real" in the sense that people believe it, and also controversial because it has little consistent evidence behind it.

Nowhere in my comment did I attack you personally. I made an analogous argument; reductio ad absurdum. LSD is also a man-made synthetic compound, and promotes neuroplacticity. And if you've ever known a meth addict, you'll know that the substance can cause significant and enduring personality change.

You're advancing a pseudoscientific theory, and I'm ripping it on its utter lack of merit. Please don't take that personally.
