Cloves used to be, and probably still are, used as a
primitive sort of
breath mint. When burned, they give off a strong smelling, dense smoke. This makes cloves the perfect
additive for
cigarettes.
Clove cigarettes were called
Krektels by their inventors, since they crackle as the ground cloves in them explode as they are burned.
Sampoerna makes some fine clove cigarettes that are widely loved by
goths.
