VAPING is helping smokers to become healthier as well as saving money.
However, try to vaping while abroad on holiday could end in having e-cigarettes confiscated - or even be put in jail.
Some countries ban the sale of e-cigarettes, but not possessing them, whereas some others ban liquids containing nicotine.
The main reason for most of these countries putting restrictions in place is a 2008 report by the World Health Organisation (WHO), which highlighted their concerns about e-cigarette use.
This was followed by a study in 2016 by WHO which recommended e-cigarettes should be banned in indoor areas or where smoking is prohibited.
The WHO said that there was insufficient evidence to suggest that e-cigarettes help smokers give up, and that they encourage younger users to experiment with different flavours.
It added that while the products are less toxic than real cigarettes, they still pose a health risk.
Vapers traveling to Thailand should leave their e-cigarettes behind or risk ending up in prison, as the country has some of the strictest laws. In South America, Argentinian and Venezuelan officials frown on personal vaporisers.
According to the UK Foreign Office, any e-cigarettes found by Thai officials are likely to be confiscated, and the owner could fined or sent to prison for up to ten years.
Brazil banned the manufacture and sale of e-cigarettes in 2014 and officials have been known to hand out fines.
Uruguay put a total ban electronic cigarettes in 2009, when health minister claimed that it is a toxic gas and the lack of proof that e-cigs were effective to quit smoking.
in Jordan, Oman and Qatar any type of cigarettes are still legal.
Taiwan classed it as a regulated drug, meaning their import and sale can lead to prison sentences and fines.
In Australia and Japan using vape pens is legal but liquid nicotine isn't. Campaign groups still fight to allow nicotine use.
Various states of India have banned it, but not in some parts of the country..
The sun reports that Hong Kong banned sales as from last month, even though vaping is actually still legal (for the moment).
Meanwhile in Europe it is totally ok as long as not in public building.
Dan Marchant, Director of Vape Club told Sun Online: "As the popularity and awareness of vaping increases around the world, the laws surrounding it are also constantly changing, so it is vital that Brits seek up to date advice before travelling.
"One other important thing to remember is to keep vape batteries in your hand luggage as they are required to be kept in a pressure controlled environment."
The Seycelles and the UAE are to legalise them later this year.
