I rarely use snus, but at times they seem appropriate. I am only familiar with General, though I did try a can of Thunder a while back. I know salt is an essential ingredient, but are any that don't taste so salty? How do I keep portions from hardening once I open a can? Can I just humidify them like other tobacco to keep them soft? Obviously a can isn't meant to last weeks after opening. I just don't use them often.
