At the moment t is illegal to import, advertise and sell vaping products in this country. (This country produces a large quantity of tobacco, which may have something to do with it. There is a suggestion that it may be legalised this year, but don't hold your breath.) It is not illegal to vape, however, or to have vaping equipment and liquids in one's possession. Tourists may bring their own equipment and liquids in with them - I don't think there is even a question about this on the customs form.
Like many things in this country there is a 'parallel market' in vaping products. You don't have to look far to find one on-line. Mostly these places will take your order on-line and deliver by moto - you pay cash on delivery.
Good luck
