I just jumped on the snuff bandwagon within the last 48 hours, and in typical junkie fashion, have been jumping in whole hog. Please note that all of my comments are from a snuff uber-noob, who is very much in the learning curve.
Snuffs that I have tried:
Dhokalia Swiss Chocolate: a nice, moist, dark brown powder with a fabulous rich, sweet chocolate flavor. Great for beginners. I could snuff this all day long.
Swisher Honey Bee: I love it. It's sweet, it's honey, it's got that great American snuff nicotine kick. I had a honey bee buzz going my entire first snuff-day at work (switching up with the swiss chocolate).
Toque Absinthe in a bullet: Stong and pungent. Painful on my first few tries; I'll have to check out that one more later. Beginners beware of trying new flavors from a bullet the first time. Without experience, it is difficult to judge how much you are getting and how strong the snuff will hit you.
Toque Honey Whiskey: I received a sample of this with my first nicotinerush order, and I really like it. It has a mesquite/barbecue kind of flavor, unusual at first snuff, but tasty.
Dean Swift Inchkenneth: Thank you TropicBob for the recommendation! It's a perfumey snuff and luscious. If it came in a perfume oil form, I'd be wearing it. It's safely in my acrylic bullet now, and it's not injured me yet from the bullet.
Dhokalia Sparrow Cool: Received this in a Dhokalia sampler pack. Again, learn from my experience here: beginners should test new snuffs with a pinch, not a bullet. I naively filled up an empty bullet with the sparrow cool, took a hearty snort, and very nearly blew my own head off!

Snorting, stomping, shaking head, tears running down...thank God I had the kitchen to myself. Sparrow cool is mentholated and a very dry, fine powder. Veterans (see snuffhouse.org forum) love the stuff, but in the hands of a beginner (in a bullet no less!) it can be a deadly weapon. I am setting that one aside for now.
My snuffing methods:
I am all over the map here, and I believe it'll take quite some time before I settle down. To complicate things further, I can bet that different snuffs will fare differently with different methods. Inchkenneth is doing well in the bullet, and I plan on keeping it there. I've done sweet snuffs (honey bee and swiss chocolate) with (1) straight pinches to the nostril, and (2) wrapping my index finger around the tip of my thumb and tapping powder onto the "snuffbox" formed at the tip of my thumbnail. I can appreciate the classic nature and simplicity of simply pinching. Bullets seem nice and convenient for out and about, and appearing as "medical devices".
Overall initial impressions:
I could get hooked on this stuff (whoops, too late!). With a good-sized pinch, a nicotine "rush" is possible, but not always predictable, especially if I've already been vaping. I think I'll be spending most of my time dabbling in the American sweet and scotch snuffs, and with some classic British snuffs like Wilson's of Sharrow and Fribourg & Treyer. Heavily mentholated snuffs don't seem to be my cup of tea at the moment.
The snuffhouse.org forum is quite large and valuable, although it's not as organized and easy-to-read as the vaping forum here on ECF.
I have ordered from nicotinerush.com and mrsnuff.com, whom both seem to be reputable and good quality online snuff merchants. Snuffing appears to be quite a bit cheaper and simpler than vaping, although the aesthetics of snuffling brown powder up one's nostrils can be potentially off-putting. My husband is a plain old cigarette and premium cigar smoker. I haven't inhaled burning tobacco into my lungs (Wahoo!) since I received my first PV. DH is a little intrigued by the vaping, but is unsure it could entirely replace smoking for him. He dips skoal in the house, and thinks it's cute that I've brought some snus home. YET, for some reason, I am hesitant to show him the snuff, for fear that he'll think I'm a complete and total nicotine nutball. Interesting...perhaps I should discuss this with my therapist...or perhaps not!
Count me in!
