I have always wondered why snuff, at least in my experience, behaves differently than other forms of tobacco and routes of administration when it comes to delivery and effects from nicotine. When I first started taking snuff I had extensive experience with cigarettes, pipe tobacco, and all forms of chew/dip. All of those forms of tobacco seemed to work relatively the same way in that the more of it and the stronger it is the more I would experience a stimulant effect. This being anywhere on the spectrum from mildly alert to heart pounding sweaty hands knocking on deaths door lol. Snuff however, many of my first times taking it I found no effect from nicotine whatsoever. I tried stronger snuffs and I tried changing my snuffing technique. I tried first thing in the morning making sure I had no other forms of tobacco first. Nothing. It was not until I dropped other forms of tobacco completely and just kept snuffing that, all of a sudden, the nicotine began to work, REALLY work. Now, snuff is my exclusive means of using tobacco and obtaining nicotine and it works perfectly. I can fine tune the snuff to my current nicotine desires, snuffs for bringing me up to desired alertness, sniffs for maintaining that without over doing the accumulative nicotine dose, and ones that are purely for enjoying aromas without any significant effect from nicotine. What's even stranger is that there are many times where even a strong snuff, depending on my mood, will have a sedative effect rather than acting as a stimulant. And times where a snuff I knew to be mild to moderate on the nicotine scale achieves a full on rousing effect. I have dabbled in to the science of this and understand a bit about how nicotine addiction can be such that nicotine will act as both a depressant and stimulant depending on ones mood, but does anyone have any knowledge or a similar experience with how snuff seems to behave as such a nicotine chameleon if you will?
