A new report from the Surgeon General's Office shows fewer Americans are smoking now than 50 years ago, but suggests there's still work to be done.
The report says only about 18 percent of American adults still light up, compared with
42 percent in 1964, when the first report linking smoking to cancer was released.
But the new report says the government might not reach its goal of driving down the number of smokers to 12 percent by 2020.
The surgeon general is asking for extra measures to fight smoking like hiking prices and expanding bans on indoor smoking.
The report also links smoking to more diseases and disorders including Type 2 diabetes, rheumatoid arthritis and erectile dysfunction.
