Thankfully I haven’t come across anything totally repulsive yet, but some of my lows are:
W.E. Garrett Sweet: Just smelled like a ground up cigar, and was so fine that it always shot straight to the back of my throat. Not my thing.
Many of the Toque snuffs: I like some of their berry scents, but most of the others I couldn’t discern anything beyond this smell of a dusty old shoe. The Toque USA Citrus did have a pleasant Citrus scent that I liked, but it was hidden behind this strong smell of wet dog, so it smelled like you were putting citrus shampoo on your dog for a bath lol
