Marlboro has produced several varieties of cigarettes with capsules in the filter, which allow smokers to customize the flavor of their smoking experience. These cigarettes are often marketed as "flavor burst" or "dual flavor" cigarettes.
The capsules are typically located in the filter of the cigarette and can be crushed or popped to release a flavor or menthol burst. Some varieties of Marlboro cigarettes with capsules include Marlboro Ice Blast, Marlboro Double Fusion, and Marlboro Double Mix.
It's important to note that smoking any type of cigarette, including those with capsules, can be harmful to your health. The addition of flavor capsules does not make the smoke any less harmful or addictive. Smoking remains a leading cause of preventable death and disease worldwide.
