"Blunts" have been invented by black Jazz musicians in the roaring twenties, when cigars of the brand Phillip Blunt have been cut open to be refilled with Marihuana. On one hand it was said that the enjoyment increased, on the other hand the smell of tobacco covered the odor of the Cannabis. Today you even call cigarettes without tobacco "blunt", but mainly the tobacco made papers to roll your own with, for blunts have to be in the same conditions as tobacco leaves are: fragrant and soft. These blunts are gently pre-treated to make them keep their odor, their freshness and their pliancy, which is very important for blunts to roll cigarettes with.
In the course of this treatment most of the blunts become valued up by adding flavour. But also blunts with original tobacco-flavour become more and more popular. Get yourself something really tasteful!
