Alaskan Natives use this with their chewing tobacco. The Punk Ash changes the alkalinity of the tobacco allowing the nicotine to readily be absorbed into the bloodstream, dramatically increasing the nicotine hit or buzz usually enjoyed.
It is often compared to the first time you ever chewed or smoked, that intense rush you felt, only with the punk ash you get that feeling everytime you dip.
It is called by many names up here, Eskimo Cocaine, Punk Ash, Iq'mik or Iqmik, Blackbull and Araq.
It will definitely knock your socks off and tie them in a knot at the same time!
The native believe it has mystical properties much like other plants possess.
The Punk Ash come from a conk or "Punk" that grows on the Paper Birch trees in Alaska, it is found on the same tree as chaga.
