How Long Does a Drug Detox Program Last?

When you take substances, whether prescribed or for recreation, there is a goal effect; after taking the same dose for a certain period of time, your body gets used to it and does not produce the same goal effect. This is when more of the substance is needed, which usually leads to abusing whatever the substance is, resulting in dependence or addiction. Your body is now used to specific amounts of the drug to function, and if the body does not receive the routine amount, you will go into withdrawal.

Depending on the type, the way they were used, and how much they were used, different drugs can create various withdrawal symptoms and have different lengths of times they occur. Usually, going through withdrawal can be very uncomfortable and dangerous to your health, depending on the drug. This is when a detox program, most likely medical detox, is needed and should be the first step into getting out of your addiction.

According to the National Institute on Drug Abuse (NIH), medical detoxification safely manages the acute physical symptoms of withdrawal associated with stopping drug use. However, medical detoxification is only the first stage of addiction treatment and does little to change long-term drug use. Although detoxification alone is rarely sufficient to help addicts achieve long-term abstinence, it is a strongly indicated precursor to effective drug addiction treatment for some individuals.

Average Length of Drug Detox

When entering into a drug detox program, there is no definite answer to how long you will be there. Detoxing from all drugs and alcohol is clearing the body of the chemicals and managing the withdrawal symptoms that come with it. Like mentioned before, there are many factors to determine your length of stay:

  • Which drug was being used
  • If a mix of different drugs were being used
  • How often do you use the drugs
  • How much of the substance the user took
  • The presence of underlying co-occurring mental health conditions
  • The user’s medical history
  • The user’s age
  • The user’s gender

Detox programs are usually 3, 5, or 7 days long, but nothing is for sure. Here is a list of different substances, their withdrawal symptoms, and the length it takes to leave your body:


First 24 hours – 2 days -Withdrawal symptoms begin, such as anxiety, insomnia, and shaking.
