Ammonia enhances cigarettes' nicotine.
Now, researchers at the Oregon Graduate Institute in Portland have confirmed that suspicion. Their experiments show that ammonia helps turn the nicotine in smoke into gas, rendering the drug more available to the lungs.
Much of a cigarette's nicotine starts out in a fairly nonvolatile, acid form, notes environmental chemist James F. Pankow, who led the study. This acid also possesses an electric charge, which keeps the nicotine from moving easily through tissue and into blood. Ammonia converts the acid form of nicotine into a free base--an uncharged alkaline form that moves more freely into the air and tissue. Pankow likens this to treating cocaine with alkaline materials to create the more lipid-soluble, potent freebase cocaine known as crack.
In the August Environmental Science & Technology, Pankow's team shows that ammonia can increase nicotine's availability as a gas by 100 times.
