Many of you probably know this little trick, so I'm posting it for those that don't. There are times when you are snuff-taking where your nose gets a little dry. This could be due to not being properly hydrated (hydrate!), or it could just be that a sufficient amount of dry snuff has gone into your nose to sort of dry things up. If the inside of your nose gets particularly dry, then any additional snuff you take will have a tendency to go too deep into your sinuses, and if you like a good back-drip, having a dry nose doesn't help get that brewing at all.
When I find myself in this situation I simply moisten my fingertips with some water, put them up to my nose, and lightly inhale some water droplets into my nostrils. Instant moisture.
Personally, I don't limit myself to just water. If I'm drinking some coffee in the morning, I'll inhale some droplets of coffee off my fingertips. Diet Mountain Dew in the afternoon...sure, why not? Enjoying a mug of root beer...yep, that'll work. I look at this method of moistening the nose as just a simple and effective way of manipulating the environment in your sinuses, to maximize your enjoyment of snuff.
