The History of Blunt Wraps, Flat Wraps, and Cigar Wrappers
A Blunt, or Flat Wrap, is a cigar wrapper, which is wider than a cigarillo and not quite as wide as full size cigar. These cigar wraps typically consist of two main parts; the inner leaf, which is similar to tobacco rolling paper and a thicker outer leaf which is rolled around the inner leaf. In most commercially available blunts, the "leaves" are not actual tobacco leaves but rather paper made from tobacco pulp.
Flat / Blunts Wraps originally got their name from their 'broad or rounded tip', and received the name around the1800s to differentiate them from other cigars.
Individually packaged Blunt Wraps leaves have been available for many years. These are tobacco leaves that, because of their nature and appearance, are used to roll a cigar in one continuous sheet (thus the name Blunt is used).
The United States Tobacco Taxation Board has classified all individual cigar wrappers as "Blunts" and taxes them as roll-your-own tobacco. Many US States classify Blunt Wraps as tobacco and a license is required to sell them and collect tax. The use of these single continuous sheets is closer to the original Blunts of the 1800s since it is not a spiral wrap.
A "blunt" may also refer to a marijuana cigar where the wrapping is a tobacco product. The spiral wrapped cigar is cut open and emptied of tobacco and the resulting shell is then filled with marijuana and resealed.
