HIGHER BIOAVAILABILITY OF MODERN NICOTINE. "Tobacco companies are using chemicals to strip salts off of the nicotine molecule (de-protonate it), allowing nicotine to more quickly and easily penetrate tissues and membranes, and making it more "bioavailable" to the lungs and brain. This rapid penetration form of nicotine is known as "free-base." https://lnkd.in/d9E4Jw4 View in LinkedIn

FREE BASE NICOTINE. Ammonia was introduced into cigarettes to convert nicotine into freebase, which is more readily absorbed and gives a stronger rush, just as was found with freebase cocaine, or crack.

THE ROOT OF THE ISSUE. "No one has ever become a cigarette smoker by smoking cigarettes without nicotine." (WL Dunn, Phillip Morris 1972).
