When I got my tin of fire and ice, I didn't even know about how to use it. A senior member from snuffhouse.com (basement shaman) kindly advised me, and now this is my current favorite in loose snus. I don't have a pris maker, so I hand-bake it. It is strongly flavored and helps me keep alert while on the job (and when I cannot use nasal snuff). I think I have quite a tolerance to nicotine, but I think anyone with lesser tolerance will find this strong. Definitely stronger then the begum chaap snuff. I would keep this in my kit always.
