An exploding cigar is a variety of cigar that explodes shortly after being lit. Such cigars are normally packed with a minute chemical explosive charge near the lighting end or with a non-chemical device that ruptures the cigar when exposed to heat. Also known as "loaded cigars," the customary intended purpose of exploding cigars is as a practical joke, rather than to cause lasting physical harm to the smoker of the cigar. Nevertheless, the high risk of unintended injuries from their use caused a decline in their manufacture and sale.
Although far rarer than their prank cousins, the use of exploding cigars as a means to kill or attempt to kill targets in real life has been claimed, and is well represented as a fictional plot device. The most famous case concerning the intentionally deadly variety was an alleged plot by the CIA in the 1960s to assassinate Cuban leader Fidel Castro. Notable real-life incidents involving the non-lethal variety include an exploding cigar purportedly given by Ulysses S. Grant to an acquaintance and a dust-up between Turkish military officers and Ernest Hemingway after he pranked one of them with an exploding cigar.
