Answer:
It depends. You must be 21 to drink, but if you drink too much you may get addicted. Similar to drugs or smoking.
Step-by-step explanation:
The younger a person starts drinking, the more likely the individual will abuse alcohol or become an alcoholic, researchers as the National Institutes of Health said Wednesday.
A new study by the National Institution on Alcohol Abuse and Alcoholism, a component of the NIH, found people who began drinking before they turned 15 were four times more likely to develop alcoholism than those who started drinking at the legal age of 21.
The study was based on information from the largest survey ever conducted on alcohol use.
Earlier research already has indicated that underage drinkers get into more accidents, run into more trouble at home and school and have a higher risk of becoming s*xually active.
