Deepika Padukone, who was forced to take up smoking for her role in Karthik Calling Karthik, was afraid that she might get addicted in the process. To prevent that from happening, she switched to smoking herbal cigarettes for her scenes.
The actress says, “After much insistence on the director’s part, I agreed to smoke in the first place. But the biggest challenge was to learn how to do it right, to lend authenticity to my character. I was also terrified that I’d get addicted, so I opted to smoke herbal cigarettes. But I hated the whole experience. It is one of the worst addictions.
