They say smoking harms you and others around you - and that includes orangutans.
Meet Tori, who learnt how to smoke by copying visitors who came to see her, and her parents.
The 15-year-old ape clutches the cigarette between her palms, and is said to make a sign with two fingers when she's in need of a nicotine fix.
15-year-old Tori has been smoking for 10 years
Now zookeepers in Indonesia are moving her to help crack down on her 10 year habit - and keep her out of the way of visitors.
Workers at Taru Jurug zoo in Solo, with a little help from the Centre for Orangutan Protection (COP), are moving her to a different part of the complex to help her kick the habit.
