I am pretty new to snuff, been using a couple months now but I would say Nicotine: Rustica homemade snuff. Great nicotine but makes my nose run bad. Difficulty: Dalohkia White (I can barely smell it out of the can without burn) I find this one has more burn than Rooster, although I only tried Rooster once. I did not like the BBQ smell. Stench: NTSU (also pretty high in nicotine, but did not really burn) This is just out of the ones I have tried, there are many out there I have not yet tried.
