Cigarettes can function as a medium of exchange, as they are commonly used as a form of currency or barter in certain environments such as prisons. However, cigarettes do not possess the characteristics of durability, divisibility, portability, or stability of value that typically apply to traditional forms of money. For example, cigarettes can easily become damaged or expire, they cannot be easily divided into smaller units for transactions, and their value is subject to fluctuations based on supply and demand.
