E-Cigarettes That Alert You When Other Smokers are Nearby

 In a much-needed development, a new ELECTRONIC CIGARETTE has been made for the social networking generation with sensors that alert smokers when someone else is lighting up nearby. 

Packs of Blu e-cigarettes, which release a nicotine-laden vapour instead of smoke, vibrate and flash a blue light when they are within 50 feet of another pack.Smokers can meet up with their fellow e-cigarette users and exchange contact details - all of which is stored electronically inside the packs of cigarettes.
The reusable packs, which also serve as a charger for the cigarettes, will go on sale next month for 80 dollars for five e-cigarettes.
The cigarette cartridges last for an average of approximately 250 puffs before they need to be replaced.
