Khat

Khat is a plant that people in some countries like to chew on. It's kind of like how some people like to chew gum.

When people chew khat, it releases chemicals in their brain that make them feel more alert and awake. Just like when you have a lot of energy after eating something sweet.

However, khat can be harmful if people use it too much or for a long time. It can cause problems like not being able to sleep, feeling anxious or irritable, and even heart problems.

Because of this, some countries have made it illegal to use khat. It's important to always talk to a grown-up if you have questions about using any drugs or plants.
