Time's up.Why is ammonia there?
RJR opted to put ammonia into Winstons and Salems in an effort to catch up to Philip Morris's Marlboro and Kool after those products surged ahead in market share. It seems ammonia increases the alkalinity of the tobacco smoke.
And so, you ask (at least, you do if you are reading the cue cards)? Higher alkalinity increases the percentage of the nicotine that is immediately available to the body. "Free" nicotine, they call it. The result is that the smoker gets a much higher immediate gratification from the same amount of nicotine.
