Like many drugs, alcohol changes your ability to think, speak, and see things as they really are. People who drink often feel very relaxed and end up making fools of themselves or doing dumb things. Alcohol also blocks the messages going to your brain. Some people lose their balance and can't walk properly. Others take unnecessary risks and may put themselves in unsafe situations.
Alcohol is really bad for kids.
At a time when your muscles and bones need to grow, alcohol stops this from happening properly. If you drink at an early age, you may be smaller than other kids. Alcohol also makes it harder for your body to fight off diseases so you'll probably get sick more often than your friends. Worst of all, alcohol affects people close to you. Your family will become worried and scared that drinking will hurt you.
