Mouth and Throat

Immediate effects of alcohol use

Being drunk can have various effects on speech, such as making people more friendly, talkative, unreserved, relaxed or argumentative. Increasing amounts of alcohol can cause aggressive, antisocial, angry, slurred and confused speech.[4, 5]

Long-term effects of alcohol use

Alcohol is a carcinogen, meaning that it causes cancers in humans. Regular alcohol use increases the risk of cancers of the mouth, throat and voicebox.[9, 15, 16] Drinking around 50g of alcohol a day (five standard drinks) increases the risk of these cancers by two to three times compared with non-drinkers, but for people who smoke, this risk is increased much more.[10, 15] Drinking more increases the risk of cancers, and drinking less decreases the risk of cancers.
