Cigarettes are heavily taxed ranging to over £7 for 20 cigarettes. 50-gram pouches of rolling tobacco are around £12. Imported brands such as Marlboro, Camel or Lucky Strike are generally the most expensive as are well-known UK brands such as Benson & Hedges and Embassy. Popular and less pricey local brands include Lambert & butler and Silk Cut (a light cigarette similar to Marlboro Light), while the cheapest brands (Mayfair, Richmond, Superking, Windsor Blue) are cheap and cheerful. Low-tar cigarettes cannot be called 'light' so terms such as 'gold' and 'smooth' are used. Most cigarettes come in low-tar and menthol varients, and many brands also sell 'Superking' (100mm length) varients too. The cheapest prices will be found in the supermarkets at the customer service counter. Almost all newsagents, supermarkets and petrol stations sell tobacco, and most will also sell some brands of pipe tobacco and cigars. For a more extensive selection of tobacco products, most towns and cities will have at least one specialist tobacconist.
The minimum age to purchase tobacco is 18 however, smoking is legal at 16. Customers who appear younger than 18 (and, in some places, 21 or 25) may be asked to produce a passport or other identification.
In some places there is a black market in considerably cheaper, imported cigarettes and you may be offered such in some pubs by certain individuals (rarely the publican or bar staff!). The health warning on these is likey to be in a language other than English. This is best avoided as this is indeed an illegal trade, and counterfeits are common.
Smoking is illegal all enclosed public places with the exception of some hotel rooms (enquire when booking). For the purposes of the anti-smoking law, 'enclosed' is defined as having a minimum of three walls and a roof, so this can include things such as 'open' bus shelters. It is also illegal to smoke at railway stations. Penalties can include a £50 'on-the-spot' fine. Most pubs and nightclubs have smoking areas which fully comply with the relevant legislation.
