The report said that quitting smoking is beneficial at any age, and can add as much as 10 years to life expectancy. It noted that the Food and Drug Administration has approved numerous medications for smoking cessation, including the nicotine patch, and other nicotine replacement therapy, and that these can be most successful when used in combination, especially with behavioral counseling.

It also said that e-cigarettes, which are a diverse and constantly changing group of products, haven’t yet been proven to be effective for quitting. In a news conference on Thursday, Dr. Adams said more research was needed on the effects of e-cigarettes.

The report was released as e-cigarettes, which deliver nicotine without the toxins of burning tobacco, remain a thorny issue for both the public health community and the Trump administration.

Millions of high school students now use e-cigarettes and many of them are struggling with nicotine addiction. At the same time, however, some longtime smokers have found the products helpful in quitting traditional cigarettes.

Even as Dr. Adams cautioned that there is no scientific evidence of the effectiveness of e-cigarettes as smoking cessation tools, he said: “We’ve heard powerful accounts from adults out there who tell us that they’ve used e-cigarettes to successfully transition from combustible cigarettes.”

In the fall, President Trump agreed to ban most flavored e-cigarettes to keep them away from minors. But after opposition from the vaping and tobacco industries and from voters who vaped, he wavered, and the administration eventually announced a new policy that bans most flavored e-cigarette cartridges but exempts menthol products as well as flavored liquid nicotine sold in open tank systems at vape shops. It also doesn’t cover disposable e-cigarettes, which are becoming more widely available and are sold in a wide range of flavors.

Erika Sward, a spokeswoman for the American Lung Association, said the new report underscored how important it is to quit smoking at any stage of life.
