2. Assume that the production and sale of marijuana are lawful under both federal and Kentuckiana state law.  However, Kentuckiana has restricted the commercial sale and use of marijuana to citizens 21 years and older.  In the interest of protecting those under the age of 21, Kentuckiana has banned marijuana advertising within 1,000 feet of schools, playgrounds, recreation centers, parks, and libraries unless the location is restricted to people aged 21 or older.  The state also banned outdoor advertising at stadiums, shopping malls, fairs, and arcades unless the locations are restricted to people 21 or older. Using the Central Hudson test, please provide your analysis as to whether advertising restriction such as this violate the Kentuckiana or United States Constitution.
