RICHMOND, Va. (AP) — Cigarette maker Reynolds American Inc. is taking its Zonnic brand nicotine gum nationwide, challenging the pharmaceutical industry’s hold and pricing power of the market for products to help people stop smoking.

The nation’s second-largest tobacco company announced the expansion plans Thursday following test markets in Iowa and Nebraska over the last two years following its 2009 purchase of Swedish company Niconovum AB, which makes nicotine gum, pouches and spray products. The move by the maker of Camel and Pall Mall cigarettes and Grizzly smokeless tobacco comes as tax increases, health concerns, smoking bans and social stigma cut into demand for cigarettes and more smokers try to quit.
