A nicotine replacement drink is on sale at Los Angeles International Airport to help reduce smokers' withdrawal anxieties as they await their flights.

Called NIC Lite, the beverage comes in 8oz bottles containing 4mg - about two cigarettes' worth - of purified nicotine infused with water and lemon flavourings.

Customers are also being encouraged to purchase the drink for in-flight consumption.

The company NIC Time has plans to roll out the drink, which has spent the last seven years in development, in more than 50 airports across the US and other locations where smoking is banned.

NIC Lite has been classified as a dietary supplement by the FDA.
