Homeless people are to be given free e-cigarette starter packs as part of a trial designed to help them quit smoking. The study will be conducted in 32 centres for the homeless across five regions in the UK – Scotland, Wales, London, the South East and the East of England. E-cigarette starter kits, which usually cost around £25, will be given for free to people at half of the participating centres. The full £1.7 million research trial will include 480 participants, with 240 in each group and 15 from each centre.
