All Nicotine is NOT the Same

Tobacco companies discovered long ago that adding ammonia to cigarette tobacco created a form of nicotine that was more addictive to the smoker.

According to studies, ammonia supercharges the nicotine as it hits the brain, by changing the chemistry of the nicotine the smoker absorbs. 

That's the reason it is difficult to compare the nicotine content of a cigarette to an equivalent amount of nicotine in an eCigarette or a nicotine patch. The nicotine in e-cigarettes and nicotine replacement therapy products isn’t as addictive as cigarettes.
