ELI5: Explain Like I'm 5

Rational addiction

Imagine you have a favorite toy that you really enjoy playing with. You might want to play with it every day or even multiple times a day. This is because playing with your toy is fun and gives you pleasure. The same thing can happen with certain things that adults enjoy like drinking alcohol or smoking cigarettes.

Sometimes people might use these things so much that it becomes a habit or addiction. This means that they feel like they need to do it even if it's not good for them. But, this doesn't mean that these people are weak or bad.

Rational addiction is the idea that people who become addicted to something like smoking or drinking, do it because they think it will make them feel better or happier. It's not just about the initial pleasure they get from the activity, but rather that they believe that the overall benefit they receive from continuing the behavior outweighs the costs.

For example, someone might smoke cigarettes because they think it helps them reduce stress or relax. They might know that smoking is bad for their health, but they still do it because the benefit of feeling relaxed is worth the risk of getting sick.

In this way, addiction can actually be thought of as a rational behavior, because the person is making a decision based on their own beliefs and weighing the pros and cons. However, over time the addiction can become stronger and it might become harder for the person to stop even if they want to.

So, remember just like how playing with your favorite toy can make you happy, some things can make adults happy too. But, sometimes people can want or need these things so much that they can't stop even if it's not good for them, and that's what we call a rational addiction.
