EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
Well, for starters, than you for answering the prompt.
But, I mean, the barebones definition of Disease is when the organism’s functions behave outside of their evolutionary purpose. I don’t think people evolved their brain’s Sigma Receptors and Dopaminergic Systems just to be triggered by Meth, much less to form a habit based on the results of that interaction, so by definition I think that fits the terminology.
And I disagree with that. Which is what you asked about.
