Cannabis, also known as marijuana, is a plant that some people smoke or eat to feel different. It can make people feel relaxed, happy, or giggly, but it can also make them sleepy or anxious.
Cannabis has a lot of different parts in it, but the part that people use to get high is called THC. THC is like a special key that fits into locks in your body called receptors. These locks and keys work together to change things in your body and brain, which is what makes you feel different when you use cannabis.
Some people also use cannabis for medical reasons, like to help with pain, nausea, or seizures. But it's important to know that cannabis can have different effects on different people, and using too much can be dangerous. It's always a good idea to talk to a grown-up you trust or a doctor before using cannabis or any other drug.
