Sometimes, people think addiction is just about making bad choices or not having enough willpower. But actually, science tells us it’s more complicated than that. Addiction is a disease, like diabetes or heart disease. It changes the brain and makes it hard to stop using drugs or alcohol. Let’s learn more about understanding addiction how this works.
How the Brain Works: The Pleasure Pathway
First, let’s talk about how the brain typically works. It has a unique system called the “reward pathway.” This pathway is like a road inside your brain responsible for making us feel good when we do things we need to survive, like eating or hanging out with friends.
A critical chemical in this process is called dopamine. When the reward pathway is working right, dopamine makes us feel pleasure. It’s like a pat on the back from your brain saying, “Good job! Do that again.”
How Drugs and Alcohol Change the Brain
Drugs and alcohol can change the brain’s reward and dopamine pathways. When someone uses these substances, they cause a big rush of dopamine in the brain, much more than what naturally happens. This big rush makes people feel really good or “high,” and they want to feel that way again and again.
But using these substances over and over again makes the brain change in a few ways:
Tolerance: After a while, the brain gets used to the drug or alcohol and the big dopamine rush. It doesn’t respond as much as before. This is called “tolerance.” To feel the same high, the person needs to use more and more of the substance.
Dependence: If the person keeps using the substance, their brain needs it to feel normal. Without it, they feel horrible, almost like having a terrible flu. These are withdrawal symptoms.
Cravings: The person might start feeling a strong desire or craving to use the substance again. This can happen even if they haven’t used it for a while. Things they see or places they go can make these cravings stronger.
Trouble Making Good Decisions: Addiction can change the parts of the brain that help us make decisions and control our actions. This means that a person with an addiction might have a hard time making good choices or resisting the urge to use the substance again.
Getting Better: Recovery is Possible
Understanding addiction and how it changes the brain helps us see that it’s a disease, not a choice. It’s not about being weak or bad. And like other diseases, addiction can be treated. Doctors and therapists have many ways to help, like medications, talking therapies, and learning new skills to handle stress and avoid triggers.
Addiction is a complicated disease that changes the brain. But with the right help, recovery is possible. By understanding addiction and how the brain and addiction work, we can treat people with addiction with kindness and help them find the help they need. Remember, everyone deserves the chance to get better.
