Negative marketing aims to discourage demand for unsafe products like tobacco. This study examines the relationship between negative marketing and tobacco utilization. It aims to determine if increased negative marketing decreases tobacco use. The study will collect data from 384 people ages 25-35 in Karachi through a questionnaire. It will assess tobacco use and perceptions of negative marketing before and after a negative marketing campaign to test the hypothesis that there is an inverse relationship between negative marketing and tobacco utilization. Limitations include only collecting data from Karachi and not inducing non-users. The study could provide insights into how negative marketing impacts tobacco consumption.
