Megastar Amitabh Bachchan has urged his fans to quit smoking.

Amitabh on Tuesday night tweeted: "World No Tobacco Day May 31, 2017, 'Tobacco – a threat to development.' I left smoking almost 35 years ago! Will you?"

The 74-year-old icon also wrote on his blog that smoking was injurious to health. 

"Quit the habit of smoking, it is injurious to health. Aarrggh… Sounding like those adverts that come before the screening of any film," he wrote. 

On the work front, Amitabh, last seen on screen as Subhash Nagre in filmmaker Ram Gopal Varma's "Sarkar 3", is prepping for his upcoming film Thugs Of Hindostan with superstar Aamir Khan and 102 Not Out with veteran actor Rishi Kapoor.
