<unk>  varies across countries and states, ranging from no<unk>  to banning them entirely. For instance, e-cigarettes were illegal in Japan, which forced the market to use heat-not-burn tobacco products for cigarette alternatives. Others have introduced strict restrictions and some have licensed devices as medicines such as in the UK. However, , there is no e-cigarette device that has been given a medical license that is commercially sold or available by prescription in the UK. , around two thirds of major nations have regulated e-cigarettes in some way. Because of the potential relationship with tobacco laws and medical drug policies, e-cigarette legislation is being debated in many countries. The companies that make e-cigarettes have been pushing for laws that support their interests. In 2016 the US Department of Transportation banned the use of e-cigarettes on commercial flights. This<unk>  applies to all flights to and from the US. In 2018, the Royal College of Physicians asked that a balance is found in<unk> s over e-cigarettes that ensure product safety while encouraging smokers to use them instead of tobacco, as well as keep an eye on any effects contrary to the control agencies for tobacco. The legal status of e-cigarettes is currently pending in many countries. Many countries such as Brazil, Singapore, Uruguay, and India have banned e-cigarettes. Canada-wide in 2014, they were technically illegal to sell, as no nicotine-containing e-cigarettes are not regulated by Health Canada, but this is generally unenforced and they are commonly available for sale Canada-wide. In 2016, Health Canada announced plans to regulate vaping products. In the US and the UK, the use and sale to adults of e-cigarettes are legal. The revised EU Tobacco Products Directive came into effect May 2016, providing stricter<unk> s for e-cigarettes. It limits e-cigarette advertising in print, on television and radio, along with reducing the level of nicotine in liquids and reducing the flavors used. It does not ban vaping in public places. It requires the purchaser for e-cigarettes to be at least 18 and does not permit buying them for anyone less than 18 years of age. The updated Tobacco Products Directive has been disputed by tobacco lobbyists whose businesses could be impacted by these revisions. As of August 8, 2016, the FDA extended its regulatory power to include e-cigarettes, e-liquid and all related products. Under this ruling the FDA will evaluate certain issues, including ingredients, product features and health risks, as well their appeal to minors and non-users. The FDA rule also bans access to minors. A photo ID is now required to buy e-cigarettes, and their sale in all-ages vending machines is not permitted in the US. As of August 2017, regulatory compliance deadlines relating to premarket review requirements for most e-cigarette and e-liquid products have been extended from November 2017 to August 8, 2022, which attracted a lawsuit filed by the American Heart Association, American Academy of Pediatrics, the Campaign for Tobacco-Free Kids, and other plaintiffs. In May 2016 the FDA used its authority under the Family Smoking Prevention and Tobacco Control Act to deem e-cigarette devices and e-liquids to be tobacco products, which meant it intended to regulate the marketing, labelling, and manufacture of devices and liquids; vape shops that mix e-liquids or make or modify devices were considered manufacturing sites that needed to register with FDA and comply with good manufacturing practice<unk> . E-cigarette and tobacco companies have recruited lobbyists in an effort to prevent the FDA from evaluating e-cigarette products or banning existing products already on the market. In February 2014 the European Parliament passed<unk> s requiring standardization and quality control for liquids and vaporizers, disclosure of ingredients in liquids, and child-proofing and tamper-proofing for liquid packaging. In April 2014 the FDA published proposed<unk> s for e-cigarettes. In the US some states tax e-cigarettes as tobacco products, and some state and regional governments have broadened their indoor smoking bans to include e-cigarettes. , 12 US states and 615 localities had prohibited the use of e-cigarettes in venues in which traditional cigarette smoking was prohibited. In 2015, at least 48 states and 2 territories had banned e-cigarette sales to minors. E-cigarettes containing nicotine have been listed as drug delivery devices in a number of countries, and the marketing of such products has been restricted or put on hold until safety and efficacy clinical trials are conclusive. Since they do not contain tobacco, television advertising in the US is not restricted. Some countries have regulated e-cigarettes as a medical product even though they have not approved them as a smoking cessation aid. A 2014 review stated the emerging phenomenon of e-cigarettes has raised concerns in the health community, governments, and the general public and recommended that e-cigarettes should be regulated to protect consumers. It added, "heavy<unk>  by restricting access to e-cigarettes would just encourage continuing use of much unhealthier tobacco smoking." A 2014 review said<unk>  of the e-cigarette should be considered on the basis of reported adverse health effects.
