Welcome to the DMT-Nexus mescalissa from Alaska,

Psychedelics don't kill brain cells. If anything they've been shown to do the complete opposite of that.

Thanks for writing up your introduction essay. Have you tried DMT yet? If not there's lots of good info in the FAQ, Wiki [listed above] and the Visual DMT diagram [listed below]

Looking forward to hearing more from you. Peace + Hyperpsace.
