2Kool2, you will find many threads on snus, dissolvables, etc., in the Alternatives section of the forum. The snus I use are little teabag-like pouches that sit between cheek and jaw in the mouth. Dissolvables go the same place, but dissolve in place. Stonewall is 4mg per piece; Ariva is 1.5mg per piece. I use Java Stonewall.
With snus, begin with low nicotine varieties.
Most snusers order from Sweden, where production meets food standards and has more than a 100-year history of safety and efficacy. I order from The Northerner. In their menu, you can also see nasal snuffs. For sheer convenience, you can't beat the Zuka Zee or Zuka Black nasal snuff that comes in a bullet (which delivers an exactly measured amount). New users have problems with pinching or measuring snuff, which is extremely finely ground tobacco.
Zuka should not make you sneeze, but if you move up to stronger snuff, you might really react by sneezing!
Read around that alternatives section and PM with any private questions. I use EVERYTHING I can legally buy!
