BANG (Middle and New Persian; in Book Pahlavi also mang, Arabicized banj), a kind of narcotic plant. In older Arabic and Persian sources banj is applied to three different plants: hemp (Cannabis sativa or indica), henbane (Hyoseyamus niger, etc.), and jimsonweed (Datura stramonium). The effects of these three narcotic plants vary, something which may explain the widely differing descriptions of bang in the Middle Persian texts. In modern Persian bang is hashish.
