BlackBerry smartphone has turned into a huge addictive device that is threatening to ruin relationships of users that own it.
This high-tech gadget nicknamed 'CrackBerry' is causing irrational and damaging behaviour among owners who can't say no.
Academics and researchers said that they are increasingly seeing people who show addictive traits when away from the gadget.
Users have become so addicted that obsessively check their emails, like hiding in the toilet to read them, and putting them under their pillow in bed so they can answer them during the night.
The growing concern is that users are suffering withdrawal symptoms more linked to drugs and alcohol when forced to disconnect from the gadget.
Dr Anthony Grant, director of the Coaching Psychology Unit at Sydney University, said that he was aware of clients who are hooked on to BlackBerry-checking.
"It's a growing practice in many financial institutions where BlackBerries are confiscated in meetings and put into a box, and people get very anxious about this. It's quite painful when it's taken away," News.com.au quoted him, as saying.
"This incessant exchange of information - a bombardment of information - has become a major factor increasing stress in the contemporary workplace," he added.
Dr Kristine Dery, Sydney University researcher, examined BlackBerry use and has found that some workers quickly become addicted to using them, while others go to extremes to avoid the gadget.
