When you hear the word
“caffeine,” the next word that

found in many other foods,
drinks, and medicines.

A drug is any chemical that changes the
way your body works. Drugs can do good
things—like medicines that cure diseases
or take away pain. Drugs can also do bad
things to your body—like heroin, cocaine,
and other street drugs. Sometimes a drug
that is harmless or
beneficial
in small
doses can be very dangerous in larger does.
