According to Fieser, the charcoal for the Lark filter was specially developed to screen out gases known to depress the action of cilia in the respiratory tract. While Larks are currently the only cigarette to use this special charcoal, there is no reason why other cigarette manufacturers could not add the substance to their filters and thereby achieve the same probable level of safety as Larks...
...cause of lung cancer is still unknown, but there is clinical evidence linking cancer with foreign matter in the respiratory system. Cilia are thin hairs that prevent such particles from lodging in the tract. The charcoal granules in the compartmentalised Lark filter adsorb such gases as hydrogen, cyanide, formaldehyde, acrolein, and ammonia, which interfere with this process...
Wanting in Elegance. Nobody knows the root cause of ulcers in the digestive tract, but what happens after the process gets started is fairly clear.

The result is a gastric ulcer. More often, the corrosive juices...

Ever since, it has been kept intact, used, where it was used at all, mainly as agricultural land and citrus groves. In recent years, its disposal has been the subject of considerable squabbling among the heirs. They finally agreed to have it planned as a regional...
