No, at least not in the UK. They do not contain tobacco and you do not need a lighter or match. The smoke in them is actually legal free vapor which is not banned in public places, So you can buy them under 18 and you can smoke them in smoking places because they don't contain any restricted or illegal parts such as tobacco.
