Banning smoking in the workplace and increasing taxes on cigarettes have discouraged teens and young adults from taking up smoking, according to a study by researchers at UC San Francisco and UC Merced.
The study, published today (Sept. 8, 2015) in JAMA Pediatrics, used data on the smoking habits of a group of 12- to 18-year-olds living throughout the country in 1997. They were tracked for 11 years as they transitioned to young adults.
The researchers found that a 100 percent smoke-free environment reduced the odds of taking up smoking by one third and that the number of new smokers plummeted over time. These effects impacted nonsmokers by protecting them from the toxins of secondhand smoke.
