How Long Does it Take For Drugs To Be Cleared From the Body?

Prescription drugs, illegal drugs, and alcohol all remain in the system for a specific amount of time after they are consumed. But the amount of time each particular drug remains in the body will depend on several factors. 

In this article, you’ll learn which factors contribute to how long specific drugs stay in your body after use, as well as which treatment options are available to help you overcome addiction.

How Long Will Drugs Stay in My Body?

The exact amount of time drugs will stay in your body will depend on several factors. These factors include:

  • Age
  • Weight
  • Sex
  • Hydration levels
  • Frequency of use
  • Dosage amount
  • Physical health
  • Any medical conditions present
  • Whether or not any other drugs were taken
  • Drug tolerance
  • Metabolic rate
  • The drug’s half-life

What is the Half-Life of Drugs?

The half-life of a drug is the amount of time it takes for 50% of the drug to be metabolized by the body and removed from the system.

A drug’s half-life can depend on several things, including your metabolic rate. It can vary from just a few hours to several weeks. Drugs with a longer half-life will stay in the body longer and therefore, appear on a drug test for longer. Drugs with a shorter half-life leave the body more quickly and appear on a drug test for a short amount of time. 

Additionally, a drug’s half life plays a role in how quickly the withdrawal symptoms will be felt. Drugs with a shorter half-life will produce physical withdrawal symptoms more quickly than drugs with a longer half-life.

Can Drugs Be Detected in Urine?

Yes, drugs can be detected in urine. In fact, a urine drug test is one of the most common forms of drug testing. This is largely because it’s easy to collect urine and also because the concentration of drugs tends to be very high. 

Drug tests such as blood testing and hair testing can typically detect drugs over a longer time period, but they are not as commonly used.

Adderall is commonly prescribed to treat ADHD. It can stay in the body for several days.

How Can I Pass a Drug Test?

To pass a drug test, do not take drugs. There are no shortcuts to take in order to effectively pass a drug test other than abstaining from the drugs themselves. 

Detox for Drug Addiction

If you’re struggling with drug addiction, detox is the first step on your path to sobriety. Detox for drug use helps to clear the body of any drugs. The withdrawal symptoms typically last a week, but this will vary depending on your overall health, which drug you were using, length of use, and the amount you were taking. 

At Enlight Treatment Center, our addiction treatment specialists will make the process as comfortable and safe as possible for you.

After your detox, our Inpatient Rehab Program provides you with around-the-clock support and enables you to live on-site at our facility.

Do You Need Substance Abuse Treatment?

  • Experience physical and mental health issues from drug use
