One of my buddies started this company just a couple years ago. The portions contain coffee grinds and a mix of stuff that you'd find in RedBull (i think Taurine and B-vitamins). I definitely get a caffeine buzz, but I don't know if they will ever serve as a nicotine replacement. I got to try their yet-to-be-released Cinnamon Roll flavor, and as a fan of all things cinnamon (mainly churros) I was a big fan. That said all the flavors are rather sweet-tasting. They're using a snus manufacturer in Denmark for the pouches and cans -- not sure who. The cans have a catch lid (not apparent from the images on the site). If anyone has seen or tried these let me know what you think.
