Seems that people who would normally light up might be using those fingers to text instead. With no cigarettes to hold it seems that text messages are what smokers might be doing more of in the U.K. following the smoking ban, which went into effect on July 1. Texting across the Orange network of 17 million mobile phone users shot up by 7.5 million texts!
The theory is that smokers need something to keep themselves occupied, and possibly as way of distraction. It has also been suggested that texting is being used as support for those trying to kick the habit!
