Personally, I find that some menthols stop me up and some don’t. McC I can use all day no problem though. For clear sinsuses though, toasts are more effective for me. McC O&G was in my first snuff order and I have bought more tins of this than any other snuff. Moisture and grind suit me as an all day snuff. I find that it has enough complexity to keep me interested. Does anyone else get a hint of bergamot in there sometimes mingling with the camphor notes?
I doubt I will ever tire of O&G. One of my first snuffs, and the one I have bought the most of so far.
