The key object of this study was to govern whether chewing and cigarette brands used in Pakistan, have prominent levels of heavy metal or not. Two metals Zinc (Zn) and Cadmium (Cd) were determined in twenty one brands (chewing and cigarettes) used in Pakistan by Atomic absorption spectrophotometry. The analytical results showed that the average concentration of Cadmium in Karachi, Pakistani brands of cigarettes analyzed was 0.099 ppm ranging from 0.174 ppm to 0.077 ppm. The average content of Cd in chewing brands of tobacco was observed to be 0.101 ppm, while the Extreme and lowest concentrations of Cd were found to be 0.115 ppm and 0.081 ppm respectively. The average concentration of Zinc in brads of cigarettes analyzed was found to be 0.247 ppm within the range of 0.422 to 0.140 ppm. The mean strength of Zinc in different chewing brands analyzed was found to be 0.196 ppm within the range of 0.269 to 0.114 ppm. In over all brands, both highest and lowest concentration of Cd recorded in brands of cigarette was 0.174 ppm and 0.037 ppm respectively. Maximum and minimum concentration of Zn recorded in over all
brands was 0.422 ppm in chewing tobacco and 0.123 ppm in cigarettes tobacco respectively.
