Drug detoxification is when someone stops using drugs and their body tries to get rid of all the bad stuff left in their system. Kind of like when you eat too much candy and your body tells you it's time to stop and maybe eat some vegetables instead!
When someone uses drugs, their body gets used to having them in their system. But when they stop using, their body gets upset and can make them feel really sick. Think of it like taking away a toy from a baby - they will cry and feel upset.
The goal of drug detoxification is to help someone get through this sick feeling and feel better. Sometimes people need to go to a special place to detox, where they can be watched over by doctors who can give them medicine to help with the sickness. Other times, people can detox at home with the help of their family and friends.
It's important to remember that detoxification is just the first step in recovering from drug use. After detoxing, people might need more help like therapy or support groups to stay on a healthy path. It's like getting a band aid when you get a boo-boo, but also needing to clean the wound and take care of it with more help.
