This research aims to analyze the awareness of Medan State University and Medan Area University (UMA) students as citizens in understanding social rights and responsibilities regarding the use of dangerous chemicals in cigarettes. The background to this research is based on the increasing consumption of cigarettes among students and its impact on health and the environment. The method used in this research is a qualitative approach with data collection techniques through interviews and observation. Interviews were conducted with students from various departments at both universities to explore their knowledge and attitudes regarding chemicals in cigarettes.
