Should e­cigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid of the habit? Reactions from Americans are mixed.More than half of the people questioned in a survey think e­cigarettes should be controlled by the US Food and Drug Administration，but 47 percent believe the e­cigarettes should be available to the smokers who want to quit.

　　“In the hunt for a safer cigarette，e­cigarettes are becoming a popular choice among those either trying to quit or looking to replace standard tobacco smoke with an alternative that manufacturers claim to be safer，” Zogby International，which conducted the survey，said in a statement.

　　About half of the 4,611 adults who took part in the survey had heard about e­cigarettes，which are battery­powered，or rechargeable cigarettes that vaporize a liquid nicotine solution.They do not produce smoke but a water vapor without smell.Sold mostly on the Internet，e­cigarettes were first made in China.

　　Last year the World Health Organization (WHO) warned against using e­cigarettes，saying there was no evidence to prove they were safe or helped smokers break the habit.The WHO said people who smoke e­cigarettes breathe in a fine fog of nicotine into the lungs.

　　Nearly a third of people questioned in the survey think that e­cigarettes should be allowed in places where smoking is forbidden，because they don’t produce smoke，but 46 percent disagree.Men who were aware of the availability of e­cigarettes were more likely than women to say they should be a choice available to smokers who want to quit.Young people，aged 18-29，and singles were the groups most open to trying e­cigarettes.Smoking is the single largest cause of preventable death worldwide，according to the WHO.
