How and why chemicals from tobacco smoke can induce a rise in blood pressure

Figure 1 Chemical formula of nicotine. One can see that the molecule is formed by a closed chain with a binding to an open chain. The latter has an N reactive atom. Open chain is responsible for major chemical reactions of the molecule.

Figure 2 Chemical formula of thiocyanate. There is evidence that the toxin has a free binding able to react chemically with other molecules to reinforce adverse cardiovascular effects. SCN: Seattle community network.

Figure 3 Benzene ring completed by an amine group, like in aniline. The group NH₂ may be changed by different nitrogen groups to form different classes of aromatic amines.
