This article discusses vegetables that may aid in quitting smoking.

A study published in the journal Nicotine and Tobacco Research found that people who ate more fruits and vegetables were less likely to stay smoke-free for at least 30 days than those who ate less. Nicotine is naturally present in these foods, which contain little amounts that are easily absorbed by the body. Nicotine products, such as nicotine pads, contain large amounts that are absorbed into the bloodstream. To quit smoking, people can use alternative habits or products like chewing gum.
