technically, all tobacco is washed, unless they're bugs in them. Nicotine content varies though. tangiers, al waha, nakhla, layalina, pharaohs, and others have .5% nic content. Starbuzz, al amir, al fakher, and the new batches of fusion come with .05% nic content.
some of the .5% brands don't give buzz though, but most do.
