Alabama has become the latest US state to ban the sale of drinks that combine caffeine and alcohol, according to reports.

Attorney for the Alcoholic Beverage Control Board, Bob Martin, has said that the drinks are "dangerous" and pose "a serious health risk". He said the production process, called fusion, makes the caffeine stronger, CBS42 reported yesterday (25 February).

Alabama is the latest state to ban such drinks, following advice from the US Food & Drug Administration late last year.
