Don't rate Irish flake as high on nicotine I bought some as an alternative to E A Carey's black twist sliced, because of reviews on line, it's nice enough but not a nicotine hit.
Look on this forum some say Carey's black twist is mad by one of the big tobacco companies. Surcharge for oldmansmoking and pick up the black twist trend.
Let me know what you buy and your view of the tobacco.
