[Families of drug addicts]

Altogether 47 families of patients suffering from narcomania were examined. It was discovered that the incidence of endogenous psychoses among the relatives of different degrees of kinship did not go beyond the populational norm. The data on alcohol abuse in the families considerably exceeded the highest parameters of normal. A tendency was noted towards increase of alcoholism proneness from the third degree of kinship to the first one in the musculine line. The genealogical analysis provided evidence on the increased rate of the hedonist and excitable traits of character in the musculine lines and of hysterical disorders in the feminine line.
