WHERE CAN YOU VAPE UPDATED: FEBRUARY 2017
Whilst in the majority of outdoor public places it is still OK to vape, many companies and methods of transport have banned vaping on their premises so we have compiled a list of exactly where to avoid vaping so you can enjoy your e-cigarette without getting into trouble!
WHERE CAN I VAPE?
TRAINS
Vaping is prohibited on all train networks, including the London Underground. Using e-cigarettes and vaping at train stations is also prohibited.
AIRPORTS AND PLANES
As with regular cigarettes, using e-cigarettes is banned on flights and can also set off alarms in the toilets so dont risk it or you could get in serious trouble!
Every airport in the UK has also banned the use of e-cigarettes except for within their designated outdoor smoking areas. London Heathrow used to allow vaping in a designated lounge but we asked them if that was still the case and got the reply we do not allow the use of e-cigarettes in our premises, so it looks like Heathrows vaping lounge is no more.
With laws relating to e-cigarettes varying from country to country, it is always best to stay on the safe side and check whether it is legal to vape in the country youre heading to before you even get to the airport as some people have had their e-cigarettes taken off them when going through security at their destination. Weve compiled a list of some of the countries where we know that vaping and/or carrying e-cigarettes is restricted scroll to the bottom of the page to find out more.
BUSES AND COACHES
We couldnt find any bus or coach companies that allow vaping on board their vehicles. We wouldnt be tempted to risk it either, you dont want to be responsible for a situation like this E-Cig on Megabus causes police search and M6 closure
TAXIS
This is entirely down to the taxi driver and/or their company policies, so always ask first and respect their wishes/policies if they ask you not to.
SPORTS STADIUMS & MUSIC VENUES
Most sports stadiums have banned vaping in their stands/grounds. Its best to assume that if you cant smoke, you cant vape. Wembley stadium does not permit the use of e-cigarettes anywhere in the grounds and you can expect the same to be said for other major UK stadiums and concert venues. The NEC in Birmingham also says that vaping is not permitted inside their buildings, although they do permit it twice a year when the fantastic Vaper Expo UK is held there.
You may find that smaller music venues or local sports clubs have a more relaxed attitude to vaping so theres no harm in asking the venue owner or a member of staff if you can use your e-cigarette inside.
HOSPITALS
Depending on where in the UK you are, the policy on vaping in hospitals can vary enormously. Hospitals in Scotland for instance have banned e-cigarettes across hospital grounds, not just in the hospitals themselves, with the exception of the NHS Lothian Trust. Though strictly speaking, there is no blanket ban on vaping in England and Wales, many hospitals do enforce a vaping ban.
RESTAURANTS
Currently, unlike with smoking, there is no blanket ban on vaping in pubs and restaurants. Many pubs will probably let you use an e-cigarette, though it is always best to check first. A number of chain restaurants and cafes, however, ban vaping across all their branches including KFC, Starbucks and Caffe Nero.
HOTELS
The vaping policy in hotels does tend to vary. Some are strict about prohibiting it and others may allow you to vape in your room. We would always recommend checking however as some hotels have very sensitive smoke alarms and no one wants to be the person who has every guest in the hotel stood outside in their pyjamas at 2am because you decided to have a late night vape (not that were speaking from experience
)
CRUISE SHIPS/FERRIES
The general consensus is that you can only vape in designated smoking areas. A lot of cruise companies have banned smoking on cabin balconies and it is likely that vaping may also be prohibited, so check with your cruise provider before you do. With regards to using them in your cabins, the same would apply as with hotels so its probably best not to vape when inside.
So the gist of it is, you cant really vape in any public indoor buildings these days, so always assume that you cant and ask any relevant authorities before doing so.
