Okay kiddo, have you ever taken medicine for a headache or a sore throat? Well, some medicines are called opioids and they can help us feel better when we have a lot of pain. But if we take too much of these opioids, they can cause problems.
The opioid excess theory is basically a way of saying that some people take too much of these medicines and it can cause them to become addicted or have other bad health problems.
Let's imagine that our bodies have little locks that only opioids can fit into. When we have pain and take an opioid medicine, the key fits into the lock and helps us feel better.
But if we take too much of these medicines, it's like putting too many keys in the lock. Our body can become overwhelmed and start to change the way it works. This can lead to things like addiction, which means we can't stop taking the medicine even if we want to, or it can make us very sick.
So it's important to always follow the instructions from a doctor or a grown-up when taking medicine, and to never take too much of it. This way, we can avoid the problems that come with the opioid excess theory.
