Jimmy carter's father made him promise not to smoke until he was 21 years old. Jimmy never smoked again, but his mother and three siblings all died of pancreatic cancer. Over 34 million americans are still hopelessly addicted to tobacco. With vaping and the legalization of pot, over five million youths around the united states use e cigarettes, and over three million used mariuana. Lung cancers connected to smoking kill nearly 500 thousand people a year, obaly seven million. It's naive to just hope that your kids won't smoke - you have to make them promise too. You have to lead from example also, because the cost of not doing it could cost you everything.
