I don't use snus often, but whenever I have used Copenhagen just to add a little variety I have always been able to take it without issue.
THIS however, was a ride and I had to get off! It is a spicy cold/hot sensation in the gums and a nicotine howitzer. I was overwhelmed by it and had to take it out. I look forward to trying again though!
The menthol is strong, but it can't hide the quality of tobacco there. These are real deal snus.
