*In this update, 70 new studies were added to the synthesis, making a total of 123 studies included. All combustible tobacco products score between 40 and 100, with bidis and smokeless (rest of world) also in this range. All other products have a combined risk score of 10 or less, including U.S. chewing tobacco, U.S. dipping tobacco, snus, heat-not-burn tobacco, electronic cigarettes, non-tobacco pouches and nicotine replacement therapy. | |||
