states, a pack of little cigars cost less than half as much as a pack of cigarettes. It is illegal for minors to purchase cigars and other tobacco products in the US, but laws are unevenly enforced: a 2000 study found that three-quarters of web cigar sites allowed minors to purchase them. In 2009, the US Family Smoking Prevention and Tobacco Control Act provided the Food and Drug Administration regulatory authority over the manufacturing, distribution, and marketing of cigarettes, roll-your-own tobacco and smokeless tobacco. In 2016, a deeming rule extended the FDA's authority to additional tobacco products including cigars, e-cigarettes and hookah. The objective of the law is to reduce the impact of tobacco on public health by preventing Americans from starting to use tobacco products, encourage current users to quit, and decrease the harms of tobacco product use. In the US, inexpensive cigars are sold in convenience stores, gas stations, grocery stores, and pharmacies. Premium cigars are sold in tobacconists, cigar bars, and other specialized establishments.

Non-traditional outlets for cigars include hotel shops, restaurants, vending machines and the Internet. Composition Cigars are composed of three types of tobacco leaves, whose variations determine smoking and flavor characteristics: Wrapper A cigar's outermost layer, or wrapper (Spanish: ), is the most expensive component of a cigar. The wrapper determines much of the cigar's character and flavor, and as such its color is often used to describe the cigar as a whole. Wrappers are frequently grown underneath huge canopies made of gauze so as to diffuse direct sunlight and are fermented separately from other rougher cigar components, with a view to the production of a thinly-veined, smooth, supple leaf. Wrapper tobacco produced without the gauze canopies under which "shade grown" leaf is grown, generally more coarse in texture and stronger in flavor, is commonly known as "sun grown". A number of different countries are used for the production of wrapper tobacco, including Cuba, Ecuador, Indonesia, Honduras, Nicaragua, Costa Rica, Brazil, Mexico, Cameroon, and the United States. While dozens of minor wrapper shades have been touted by manufacturers, the seven most common classifications are as follows, ranging from lightest to darkest: Some manufacturers use an alternate
