Ayushmann Khurrana who is a non-smoker in real life had a hard time learning to smoke for his upcoming film 'Dum Laga Ke Haisha'.

The actor will be seen handling a cigarette quite a few times in his film. And this is the first time he will be shooting a scene while smoking or smoking in real life too.

When Ayushmann was described the scene, he requested the director to change the smoking part of it. But it was a very important requirement of the scene and hence, Ayushmann practiced smoking.

After a couple of initial glitches and coughs, he mastered the act and gave a natural and effortless shot.
