We examine the optimal design of public policies directed at controlling the consumption of tobacco. The public authority uses two types of instruments: (i) an excise tax, that hinders consumption by increasing the price of cigarettes, and (ii) prevention and control programs, that reduce smoking by increasing consumers\u2019 awareness about future health harm.
