Сигаретный табак и бумага а также табачный дым - источник ртути. И ртуть не задерживается особо никакими фильтрами. Вообще в дыму содержится КУЧА химикатов, включая высокотоксичные и прочие вещества, вызывающие рак. Формальдегид, бензол, мышьяк и прочие. Эти вещества взаимодействуют с тканями организма, когда контактируют с ними. Когда дым достигает легких, он осаждается в виде смол.
Да что там, может вас КОЛИЧЕСТВЕННО убедит? Читаем внимательно:
