The theme of my thesis is The National Tobacconists’ effect on the consumer behaviour in Hungary. I have been following with attention the news and changes which are in connection with the smoking, purchasing habits and tobacconist’s since June of 2013 as an owner of The National Tobacconist’s. I have chosen this theme not only because of its actuality, but I have chosen it in order to support the advancement of my business enterprise thereby I can get acquainted with the smoking habit of the customers. Consequently, the main target of my thesis is the analysis of the effects on the consumer attitude of the opening of The National Tobacconist’s.In the literature review the short history of the dicovery and the spread of the tobacco, the economic effect, the structure of the Hungarian tobacco economic units, the smokers customs have been introduced on the score of surveys. Henceforward I have observed the regulations which led to the opening of the National Tobacconist’s, the domestic turnover of the black market and with the opening of the tobacconist’s what kind of changes have been made on the tobacco market.
