Big-four cigarette maker Japan Tobacco International (JTI) has launched its first tank e-cigarette nationwide.
JTI's New Logic PRO tank e-cigarettes have been available at Sainsbury's stores since January, but were launched nationwide this month and will be boosted with a TV and outdoor media campaign from 1 May.
Tanks are the cartridges that hold the e-cigarette's vaping liquid and can be replaced when empty.
The launch comes a year after JTI bought one of US' leading independent e-cigarette makers, Logic, last April.
Founded in 2010, Logic specialised in rechargeable, ready-to-use and disposable e-cigarettes, including the Logic Pro tank system.
Around 85 per cent of vapers use tank e-cigarettes, equating to around two million regular users in the UK.
A study by Public Health England released last year concluded that vaping is 95 per cent less harmful than tobacco.
