I've read conflicting reports and have heard that one clove cigarette is equivalent to smoking an entire pack of regular cigarettes. Please give me your advice.
Clove cigarettes are just tobacco with clove flavor.
That may mean tobacco mixed with cloves, but often it means tobacco mixed with artificial clove flavoring and fragrance. Clove cigarettes often are unfiltered, so you may get three times as much tar from them as from a regular Marlboro. Still, I can't believe that smoking one clove cigarette is equivalent to smoking an entire pack of regular cigarettes. That makes no sense. But clove smoke can be more irritating than that of regular cigarettes, depending on individual sensitivity.
