Have you considered reading the FDA's ban press release?

One study suggests that banning menthol cigarettes in the U.S. would lead an additional 923,000 smokers to quit, including 230,000 African Americans in the first 13 to 17 months after a ban goes into effect. An earlier study projected that about 633,000 deaths would be averted, including about 237,000 deaths averted for African Americans.
