Ammonia is not used in tobacco blends. The blend is as it says a blend of different components but paper and filter also add to the whole design.
And for your information, the smoking machines used in the industry measure exactly the content of nicotine after a few more analytical methods used on the 'catched' nicotine. The machine does not just simply sucks a cigarette but it mimics the habit of a usual smoker (sucking, resting, sucking, resting) and catches the smoke on a filter. Bit more complicated then you explained.
The anhydrous ammonia is used on ALL tobacco cigarette products in the USA, China, etc... That includes blended types, which in any case are nothing more than an oxymoron to the industry at large. The DR does NOT process the primer mix with petroleum based anhydrous ammonia sourced from the LA market or the Methane derivative from the US sourced market for the local lines! That's true 100%!!!
All others aimed at exports are treated 100% to the process!
As far as the "smoking" machines and what not, I simply made the example of a person carrying out the tests by simple means at home with easy to get stuff. The filters will be more than enough to provide evidence of the two by visual inspection alone...
Paper is nothing much of a vessel for the product, the filters are nothing out of this world and very, very simple as well...
Nicotine presence is easy to identify by the caramel coloring (tones, saturation) left behind on the tar captured by the filter. The more intense the amber to crimson, the more intense the nicotine presence in the tar left behind. Nicotine oxidizes the tar present on exposure to the oxygen in the air and the tone/saturation helps in visually telling how much concentration was present during the combustion during smoking. That effect is there due to how the nicotine own's miscibility allows the concentration to be increased on the primer mix of tobacco cigarettes when using the anhydrous ammonia as catalyst.
On Dominican cigarettes a lot of the nicotine is vaporized and burned during the combustion as smokers take a sucking, the rest goes to the filter and some of that into the lungs. In US aimed cigarettes/exports, the nicotine level on the tobacco used for the filler is greatly concentrated and the vapors will reach combustion point only at higher temperatures than normal with a non-anhydrous ammonia treated tobacco mixture. A DR cigarette will not only have less strength than a US one, but also last less in being fully burned as the combustion point is lower than the anhydrous ammonia treated tobacco primer mix.
I know a lot of Dominicans that smoke and when they travel to the US, they must pick the light or ultra light version of the regular cigarette brands they use in DR there. For a US smoker taking a puff from a regular box of DR cigarettes of their label brand in the US, feels exactly like smoking the light or ultra light versions of those here.
The chambers where they use the anhydrous ammonia for the primer mix looks like a overblown lab... The only thing they don't show you when you take a tour of the premises... I got to see it plenty of times as my uncle worked there for more than 25 years...
The treated tobacco smell is intense and overwhelming!
Thanks God they feel it's not worth the expense to treat the stock for local sales, on the basis of savings...
