Addiction is a disease that affects your brain and behavior. When you’re addicted to drugs, you can’t resist the urge to use them, no matter how much harm the drugs may cause. The earlier you get treatment for drug addiction, the more likely you are to avoid some of the more dire consequences of the disease.
You can also get addicted to prescription or illegally obtained narcotic pain medications, or opioids. This problem is at epidemic levels in the United States. In 2018, opioids played a role in two-thirds of all drug overdose deaths.
