   To estimate the effect of cigarette taxation on its consumption, data from cigarette sales were collected and analyzed across 39 states in the United States from the years 1970 to 2000. Proposition 99, a Tobacco Tax and Health Protection Act passed in California in 1988, imposed a 25-cent per pack state excise tax on tobacco cigarettes and implemented additional restrictions, including the ban on cigarette vending machines in public areas accessible by juveniles and a ban on the individual sale of single cigarettes. Revenue generated was allocated for environmental and health care programs along with anti-tobacco advertising. We aim to determine if the imposition of this tax and the subsequent regulations led to a reduction in cigarette sales. The data is in the CSV file smoking2.csv.
