The popular craze of vapour tobacco products, including e-liquid and e-cigarettes has seen sales of the products double to $6 billion since 2013.
According to figures from Euromonitor sales increased by 59% to £3.9 billion, with the US seeing the biggest increase to £1.7 billion.
In a comparison, other nicotine replacement products such as patches and gum decreased by 3% to £137 million whilst e-cigarettes increased 75% to £459 million as British consumers strive for a healthier lifestyle.
Senior tobacco analyst at Euromonitor, Shane MacGuill said he was “hesitant” to conclude from the global data that consumers trying to kick the habit are increasingly choosing e-cigarettes over more traditional therapies, but said that the trend in bigger markets such as the UK “does look a lot like correlation and perhaps even causation”.
