Nasal snuff, like any other nicotine delivery system, may take some time to get accustomed to. When many folks vape for the first time, they cough from the new type of mist they are inhaling. The same goes with snuff. There is a slight to moderate burn when first starting. Sneezing is very common and nose blowing is almost mandatory.
You can use snuff to provide nicotine dosing just as you would
vaping or smoking an analog. That said, just because snuff was a habit of aristocrats of long ago is no reason to start using the stuff. Snuff is an interesting way to provide nicotine in a discreet, yet pleasurable way, when smoking or vaping is not possible. Snuff is not for everyone so tread lightly at first if this form of nicotine dosing is of interest to you.
I recently began using snuff and my eyes watered several times from the intense feeling in my nose. After several doses, that 'burning' goes away. The nicotine rush that some users describe is really mellow in my experience, but it does exist. If you are interested in starting, feel free to PM me for more information. While I am not anywhere near an expert; a newbie helping a newbie works for me.
