The way addiction affects the brain can be puzzling. Some people can control their alcohol or drug use, while others can’t. This is because everyone’s genes, upbringing, and life experiences are unique.
There isn’t just one gene or bad experience that causes drug or alcohol addiction. It’s a mix of many things that build up and make someone more likely to have a problem. Not everyone with this likelihood will actually become addicted. Often, different things trigger substance abuse, and additional factors work together to make the addiction stronger.
Feeling Good and Rewarded
When drugs or alcohol are used, they flood the brain with chemicals that make you feel different. This can be overwhelming, especially if used too much. But for someone prone to addiction, it’s really enjoyable. Even people struggling with mental health issues might find relief in this.
If someone likes how it feels, their brain remembers and tells them to do it again. The brain doesn’t tell the difference between something good or something harmful. Addiction happens when someone keeps using too much to chase that good feeling.
Over time, they need more and more to get the same effect, and their life becomes mostly about using and recovering. When addiction is serious, a person’s focus narrows down to only thinking about drugs or alcohol. This is because the brain is so fixed on getting the reward from these substances that it forgets about other things that could make them happy.
