While it's been a year since he gave up smoking, Hrithik Roshan is trying to help his colleagues in the industry to kick the butt as well. The latest is that the actor presented a copy of 'The Easy Way To Stop Smoking' by Allen Carr to Sanjay Dutt, during the shoot of 'Agneepath' in the city, on Sunday.

The book proved to be handy for the star as it helped him banish the cancer stick for the sake of his kids, Hrehaan and Hridaan. A source reveals that the subject of smoking came up when the two actors were chatting in between shots during the previous schedule.

"Sanjay spoke about how he avoided lighting up in the presence of his twins, Shahraan and Iqra. That's when Hrithik recalled quitting the habit last August, after reading Allen Carr's book. And he promised to give the actor a copy when they met during the next schedule," recalls our source, adding, "When leaving from home for the shoot, Hrithik ensured that he had taken a copy for his co-actor."

Predictably, Sanjay was surprised when Hrithik handed him the book. "When Sanjay arrived at the location, Hrithik carried the book to give it to him immediately. Sanjay thanked Hrithik and hugged him as a gesture of appreciation and concern," says our source.

Reportedly, Hrithik had taken to smoking earlier as his character Ethan was required to light up in Sanjay Leela Bhansali's 'Guzaarish'. However, after the film ended, the actor continued to smoke off screen as well, though he was careful to avoid smoking at home to ensure that his sons didn't see him light up.

"It took him a while to quit. Eventually, it was Allan Carr's book that helped him kick the butt," our source recalls, adding, "Since August 5 of last year he hasn't lit up even once."

We wonder if Hrithik will soon be handing out a copy of this book to his good friend Shah Rukh Khan as well. The only time SRK kept his smoking in check was post his shoulder surgery in the US over seven years ago. And Sanjay in turn could hand out copies to his close chums Ajay Devgn and Salman Khan.
