Position of medical organizations
As of 2014[update] electronic cigarettes have not been approved for helping people quit smoking by any government.[1] In July 2014, a report produced by the World Health Organization (WHO) for the Conference of the Parties to the WHO Framework Convention on Tobacco Control, found there was not enough evidence to determine if electronic cigarettes can help people quit smoking. It suggested that smokers should be encouraged to use approved methods for help with quitting.[1] But the same report also mentioned expert opinions in scientific papers that suggested e-cigarettes may have a role helping people quit who have failed using other methods.[1] A previous WHO statement from July 2013 stated that e-cigarettes have not been shown to be effective helping people quit smoking.[2] It also recommended that "consumers should be strongly advised not to use" e-cigarettes unless a reputable national regulatory body has found them safe and effective.[2] The World Lung Foundation applauded the 2014 WHO report's recommendation for tighter regulation of e-cigarettes due to concerns about the safety of e-cigarettes and the possible increased nicotine or tobacco addiction among youth.[3]
The UK National Health Service has concluded, "While e-cigarettes may be safer than conventional cigarettes, we don't yet know the long-term effects of vaping on the body. There are clinical trials in progress to test the quality, safety and effectiveness of e-cigarettes, but until these are complete, the government can't give any advice on them or recommend their use."[4]
In 2014, the US Food and Drug Administration (FDA) concluded, "E-cigarettes have not been fully studied, so consumers currently don't know: the potential risks of e-cigarettes when used as intended, how much nicotine or other potentially harmful chemicals are being inhaled during use, or whether there are any benefits associated with using these products. Additionally, it is not known whether e-cigarettes may lead young people to try other tobacco products, including conventional cigarettes, which are known to cause disease and lead to premature death."[5]
Smoking cessation
As of 2014[update], research on the safety and efficacy of e-cigarette use for
Two 2014 reviews found no evidence that e-cigarettes are more effective than existing nicotine replacement treatments for smoking cessation.[11][15] Studies have not shown that e-cigarettes are superior to regulated medications for smoking cessation.[8] A 2014 review found four experimental studies and six cohort studies that indicated that electronic cigarettes reduced the desire to smoke and withdrawal symptoms.[16] This review also noted that two cohort studies found that electronic cigarettes led to a reduction in the number of cigarettes smoked per day.[16] Nicotine-containing e-cigarettes were associated with greater effectiveness for quitting smoking than e-cigarettes without nicotine.[12] A 2014 review concluded that the adverse public health effects resulting from the widespread use of e-cigarettes could be significant, in part due to the possibility that they could undermine smoking cessation.[17] This review therefore called for their use to be limited to smokers who are unwilling or unable to quit.[17] A 2014 review found that the research suggested that personal e-cigarette use may reduce overall health risk in comparison to traditional cigarettes.[18] However, e-cigarettes could have a broad adverse effect for a population by expanding initiation and lowering cessation of smoking.[18] A 2014 review found that the evidence suggests that "e-cigarettes are not associated with successful quitting in general population-based samples of smokers."[19]
Safety
The risks of electronic cigarette use are uncertain,
One review found they appear to be similar in
Tobacco harm reduction has been a controversial area of tobacco control.[29] The health community have been reluctant to support harm reduction efforts, in part in response to tobacco industry deception.[29] A 2014 review found no long-term evidence on the efficacy of e-cigarettes in reducing harm from tobacco related disease or improving the health of the population as a whole and concluded promotion of e-cigarettes as a harm reduction product was premature.[15] A different review found e-cigarettes would likely be less harmful than tobacco cigarettes to users and bystanders, if at all.[30] The authors warned against the potential harm of excessive regulation and advised that health professionals may consider advising smokers who are reluctant to quit by other methods to switch to e-cigarettes as a safer alternative to smoking.[30] A 2014 review argued that regulations for electronic cigarettes should be similar to those for dietary supplements or cosmetic products to not limit their potential for harm reduction.[24] A 2012 review found electronic systems appear to generally deliver less nicotine than smoking, raising the question of whether they can effectively substitute for tobacco smoking over a long-term period.[22] A 2012 review found e-cigarettes could considerably reduce traditional cigarettes use and they likely could be used as a lower risk replacement for traditional cigarettes, but there is not enough data on the safety and efficacy to draw definite conclusions.[31] E-cigarette use for risk reduction in high-risk groups such as people with mental disorders is unavailable.[32]
Smoke from traditional tobacco products has 40 known carcinogens among the 10,000 chemicals it contains, none of which has been found in more than trace quantities in the cartridges or aerosol of e-cigarettes.[29] A 2011 review stated that while e-cigarettes can not be considered "safe" because there is no safe level for carcinogens, they are doubtless safer compared to tobacco cigarettes.[29] Any residual risk of e-cigarette use should be weighed relative to the risk of continuing or returning to smoking, taking account of the low success rate of currently-approved smoking cessation medications.[26] Adults most frequently use electronic cigarettes as a replacement for tobacco, but not always to quit.[33] Although some people have a desire to quit smoking by using e-cigarettes, another common explanation for the use of these products is to cut back on traditional cigarettes.[19]
In 2014 a report commissioned by Public Health England concluded that there is large potential for health benefits when switching from tobacco use to other nicotine delivery devices such as electronic cigarettes, but realizing their full potential requires regulation and monitoring to minimize possible risks.[34] They found that the evidence suggests that a considerable number of smokers want to reduce harm from smoking by using these products.[34] The British Medical Association encourages health professionals to recommend conventional nicotine replacement therapies, but for patients unwilling to use or continue using such methods, health professionals may present e-cigarettes as a lower-risk option than tobacco smoking.[35] The American Association of Public Health Physicians (AAPHP) suggests those who are unwilling to quit tobacco smoking or unable to quit with medical advice and pharmaceutical methods should consider other nicotine containing products such as electronic cigarettes and smokeless tobacco for long term use instead of smoking.[36] In an interview, the director of the Office on Smoking and Health for the U.S. federal agency Centers for Disease Control and Prevention (CDC) believes that there is enough evidence to say that using e-cigarettes is likely less harmful than smoking a pack of conventional cigarettes. However, due to the lack of regulation of the contents of the numerous different brands of electronic cigarettes and the presence of nicotine, which is not a benign substance, the CDC has issued warnings.[37] A 2014 WHO report concluded that some smokers will switch completely to e-cigarettes from traditional tobacco but a "sizeable" number will use both tobacco cigarettes and electronic cigarettes. This report found that such "dual use" of e-cigarettes and tobacco "will have much smaller beneficial effects on overall survival compared with quitting smoking completely."[1]
Addiction
A number of organizations have concerns that e-cigarettes might increase addiction to and use of nicotine and tobacco products in the young.[38][39][40] These include the Centers for Disease Control and Prevention, the International Union Against Tuberculosis and Lung Disease, the American Academy of Pediatrics and the Food and Drug Administration.[37][41][42][43] The World Health Organization raised concern of addiction for nonsmokers from their use in July 2013.[2] The National Institute on Drug Abuse stated that there is a possibility that they could promote continuation of addiction to nicotine in those who are attempting to quit.[39]
