The ordinance is a few pages long- but essentially it will limit the sale of tobacco including electronic cigarettes to only people over 21. It'll require retailers that sell tobacco and e-cigs to get a license (the city will do compliance checks).
Fines for retailers who violate the ordinance will begin with a $500 fine. A 2nd violation within 36 days will be a $750 fine (and a loss of the ability to sell tobacco products for a week). A 3rd violation within 36 days increases the punishment to $1,000 and 30 days of no-sell. A 4th violation is a $1,000 and the retailer won't be able to sell tobacco products for 3 years.
Perhaps next legislative session a bill will move forward that establishes a statewide Tobacco 21 law.
