The human experience of the world (thoughts, vision, audition, pleasure, fear,...) is triggered by the nervous system (including the brain) that reacts on bio-chemistry.
Changing the bio-chemistry changes the human experience but gives no super powers. Most likely your thoughts on drugs are less smart but appear smart to you. Similar to other drug intoxications that disturb the normal brain activity and the sober judgement of your thoughts and experience of reality.
Granted, some people have been able to solve some of their problems with psychedelics because they are strong destabilizers.

I am in favor of using psychedelics as last resort medicine under supervision of a medical expert.
But I am against the promotions of psychedelics by people who are either lucky (no bad life changing effects for months or years because of drug induced trauma with PTSD or bad neuroplasticity) or suffer already from psychosis.
