S.M. Blue is one of my favorite medicated snuffs. It's great for clearing my sinuses and has a lovely, refreshing cooling sensation that I just can't get enough of. I find it to be very easy to sniff. I typically use it in a bullet and I've never oversnuffed it.
This is a wonderful snuff. The only reason it gets a 4 instead of a 5 from me is because it isn't a snuff that I can use all day. Rather, it's the kind of thing I turn to in times where my nose is stuffy or I just want to experience its relaxing cooling sensation. S.M. Blue is one I'll always keep around. Great snuff, highly recommended to anybody who enjoys medicated snuffs.
