Depends on your referential. Within humanity, addiction takes very different form. Compared to mosquitos, our addictions are probably still very similar, yes.
I think I fail to see your point though.
Are you saying people tend to exaggerate how different addictions are, for example to better sell some new addiction overcoming books or courses?
They're likely just disagreeing to be pedantic. I struggle with this addiction just like coldtea does...although my experience with it is pretty unique ;)
