Lucky Strike, because it’s toasted 
I was reading on that today. At its peak they were selling something like forty-billion of those a year and it dominated as number one brand in the 1930s. One thing with grinding, I’m not really sure on the sizing for coarse grind. Here’s a link to a pic.click for image
This is just a thought. I love turkish coffee. They sell hand crank brass machines. The bean has got to be a powder. Why not use it for snuff? they look like a cylinder with a hand crank.
^ good call! Turkish Coffee is fantastic but I’m not sure if the grinders will cut it right since turkish coffee grounds seem to be more dense than snuff.
I think the only problem will be the leaf ribs. They’re almost impossible to grind finely by hand unless they completely dry and chopped small.
I’m surprised no one’s mentioned menthol crystals yet. They can be purchased very cheap and REMEMBER THIS: extremely small amounts are needed! Read up on menthol crystals before you use them!!! I cannot put enough exclamations for that warning!! I know a shop around here sells them (they have a huge herb collection, try stores like that) and they’re easily found online.
