Effect on Your Brain
Your brain is wired to make you want to repeat experiences that make you feel good. So you’re motivated to do them again and again.
The drugs that may be addictive target your brain’s reward system. They flood your brain with a chemical called dopamine. This triggers a feeling of intense pleasure. You keep taking the drug to chase that high.
Over time, your brain gets used to the extra dopamine. So you might need to take more of the drug to get the same good feeling. And other things you enjoyed, like food and hanging out with family, may give you less pleasure.
When you use drugs for a long time, it can cause changes in other brain chemical systems and circuits as well. They can hurt your:
- Ability to learn
Together, these brain changes can drive you to seek out and take drugs in ways that are beyond your control.
Who’s Most Likely to Become Addicted?
Each person’s body and brain are different. People also react differently to drugs. Some love the feeling the first time they try it and want more. Others hate it and never try again.
Not everyone who uses drugs becomes addicted. But it can happen to anyone and at any age. Some things may raise your chances of addiction, including:
- Family history. Your genes are responsible for about half of your odds. If your parents or siblings have problems with alcohol or drugs, you’re more likely as well. Women and men are equally likely to become addicted.
- Early drug use. Children’s brains are still growing, and drug use can change that. So taking drugs at an early age may make you more likely to get addicted when you get older.
- Mental disorders. If you’re depressed, have trouble paying attention, or worry constantly, you have a higher chance of addiction. You may turn to drugs as a way to try to feel better. A history of trauma in your life also makes you more likely to have addiction.
- Troubled relationships If you grew up with family troubles and aren’t close to your parents or siblings, it may raise your chances of addiction.
