i want to introduce you with marasotu. Rustica leaves are mixed with (oak) ash 1/1 ratio and the moisture is 50%. It is used like snus but gives a tingling sensation. It is sold in 25g loose packs so you need thin cigarette papers to make your portion. As far as i know from the press it is also sold in UK at some turkish markets.
History: it is told that in WW I french soldiers came to maras and some other cities with this type of tobacco and the local people learnt how to make it.
