What are your opinions & what should i know about nicotine vapor inhalers? better than cigarettes, i'd think, but i want a professional opinion?

E-cigs: It is definitely better than cigarette as the tar is removed which is the more carcinogenic part. It should be used in decremental manner to get off smoking . It is still addicting as it has the nicotine. It causes vasoconstriction and increase in blood pressure, it causes deposition of cholesterol in blood vessels, and despite not known to be carcinogenic it may trigger cancer cells to multiply.
