I dont think your loosing your mind. I think they must have changed this blend at some point in time. The initial reviews from when it first released didnt mention anything about a topping/flavoring, Only the more recent ones did and my tin was from 12/22I've considered opening one of my older tins of Red Hunt to see if I'm losing my mind.
Something about having two open tins of the same blend just irks the hell out of me though.
Maybe they had an F up at the plant and stuck something else in the tin? Who knows but this smell is unmistakable and overwhelming
