[Deleterious effects of tobacco-contained nickel].

In the study, an attempt was made to demonstrate whether cigarettes-contained nickel may exert deleterious effects in anybody or only in defined groups of individuals and what is the theoretical ground of the nickel unfavourable action. Do those negative results stem from augmented level of nickel in the environment and its transfer to human vicinity or do they reflect personal traits of affected people, who share certain predisposition which may lead to morbid sings/symptoms when such persons smoke or are exposed to environment of smokers.
