A blunt is a cigar which wider than a cigarillo but not quite as wide as a traditional cigar. They consist typically of two parts: the inner leaf, which is similar to a cigarette rolling paper and a thicker outer leaf which is rolled around the inner leaf in a spiral. In most commercially available blunts, the "leaves" are not actual tobacco leaves but rather paper made from tobacco pulp.

Blunt also can refer to a marijuana cigarette where the wrapping is a tobacco product. The cigar shell is emptied of tobacco and the resulting shell is then filled with marijuana and then rolled.
