Heroin detox is essential because it helps to remove the physical dependence on the drug. Without detox, the body will continue to crave heroin, and it will be difficult to stop using it. It's essential to speak to a healthcare professional to determine if detox is necessary for the individual.

Detox is only the first step in treating heroin addiction. While it's an important step, it's not enough on its own. Once detox is complete, it's crucial to continue with addiction treatment. This can include therapy, support groups, and medication-assisted treatment.

The length of heroin detox can vary from person to person. Typically, it takes five to seven days for heroin to completely leave the body. However, the symptoms of withdrawal can last for several weeks.
