Cocaine and amphetamine regulated transcript

Okay, kiddo, so there's this thing inside our bodies called "cocaine and amphetamine regulated transcript" or CART for short. It's like a messenger that tells our brains and bodies what to do.

When we eat, CART is released and it tells our brain that we've had enough and we should stop eating. It also helps us burn calories and keeps our body weight in a healthy range.

But there's something called drug addiction, where people take drugs that can harm their body and make them feel good temporarily. These drugs can mess up CART, so it doesn't work properly anymore. This can lead to overeating, weight gain, and addiction.

So, it's important to take care of ourselves and not do things that can hurt our brain chemistry and our health. And if we ever feel like we're struggling with addiction, we should ask for help from trusted adults or medical professionals.
