What is tolerance?

People who drink regularly become less affected by alcohol as their bodies get used to it. They then need to drink more for it to have the same effect. This is called developing a tolerance to alcohol. Although people who've developed high tolerance may not feel drunk, they still run a serious risk of damaging their health.
