Emraan Hashmi bid adieu to smoking a long time back but little did the actor knew he would have to chew tobacco soon. To play a foul-mouthed reporter in Dibakar Banerjee's "Shanghai", he had to re-start the habit.

On the first day of the shoot, Emraan was asked to chew tobacco for a scene and it was not a pleasant experience. Tobacco left him with such a distaste that Emraan almost threw up and felt giddy.

The director insisted that since his role required him to do it, there was no other way out. After a lot of discussions, Banerjee and Emraan came to the conclusion that the actor should chew tobacco.
