The right answer is 20 and 30%.
According to a scientific study, it was discovered that alcohol or tobacco users were between 20 and 30% more likely to develop esophageal cancer. Simultaneous users of alcohol and tobacco are three times more likely to develop it.
The harmful effects of alcohol and tobacco do not add up, they multiply. At least 75% of cancers of the throat and head (oral cavity, pharynx, larynx) are attributable to a combination of tobacco and alcohol. Men who consume alcohol and tobacco are 38 times more likely to develop one of these cancers than a man who does not touch one or the other.
