Okay, kiddo, imagine your brain is like a big control center that helps you think, feel, and make decisions. Sometimes, when people use drugs or alcohol, it can mess with that control center and make them see or hear things that aren't really there, or believe things that aren't true. That's called a substance-induced psychosis.
It's kind of like when you watch a movie and it's so scary or intense that it makes you feel like you're part of the story. Your brain is tricked into believing something that isn't real.
But when someone is having a substance-induced psychosis, it's not just for a little while like when you watch a movie. It can last for days or even weeks, and it can be really scary for them and the people around them. They might act weird, talk to themselves, or do things that don't make sense.
The good news is that substance-induced psychosis usually goes away when the person stops using drugs or alcohol. But it's important to get help from a doctor or a therapist to make sure they're safe and get the right treatment. And remember, it's always best to stay away from drugs and alcohol until you're old enough and have talked to an adult you trust about them.
