Yeah, it just means a stronger, better-tasting cigarette.
The thing is that they have to bleach out the tobacco. Remember that scandal about cigarette companies "spiking" tobacco with extra nicotine? As I understand it, that's what happens after bleaching; otherwise, crappy cigarettes like the front-tier cigarettes (Marlboro, Camel, &c.) would be inconsistent.
Of course, here's the fun thing: in cigarette smoke, there is both ammonia and bleach.
