How Long Do Drugs Stay In Your System?

How Long Do Drugs Stay In Your System?  Drug Detection Times indicate a point in time in which drug testing can reveal the presence of the drug metabolites in your urine, hair or saliva.  This includes the time from when the drug can first be detected to the point in time when you will test clean.

How Long Do Drugs Stay In Your System?  The Most Accurate Drug Detection Times.Your Drug Detection Times Can Vary Based Upon:

  1. The Drug Consumed.  Each system creates a different metabolite for each drug.  Metabolites are a product of your metabolism.  Some of these metabolites stay in your system a long time.  An example of this is the marijuana detection time which can be in excess of 60 days.  This is an extreme as most drug detection times are much less.  The marijuana detection time for s urine drug test  can be up to 60 days and for a hair drug test in excess of 90 days. The marijuana detection time is an extreme as most drug detection times are much less.
  2. The Type Of Drug Test.  Each drug test also has a differing drug detection time.  The hair drug test is always at least 90 days and could be longer in certain instances.  The blood test is usually the shortest with drug detection times of only several days.  The mouth swab drug test, sometimes called the saliva drug test, detection times are usually less than a seek.  Where as the urine drug detection times are usually less than a month.
  3. Your Usage Level.  Typically the more you use the longer the drug detection time for that drug.  The exception to this rule in the hair follicle drug test detection times.  They are always in excess of 90 days no matter your usage level.
  4. Your Personal Factors.  There are a number of your personal factors which can either shorten your drug detection time or lengthen your drug detection time.
    • Metabolic Rate
    • Body Mass
    • Physical Activity
    • Age
    • Overall Health.
    • Drug Tolerance
    • Metabolic Rate

We will discuss these in greater detail later in this article.

 

The Four Main Types Of Drug Tests Explained.

It is very important that you first identify which drug test you are facing and learn a bit about how to pass that drug test.

How Long Do Drugs Stay In Your System for A Urine Drug Test?

Know how long do drugs stay in your system for a urine drug test.  The urine drug test is the most common due to its simplicity to administer, accuracy and immediate results.  

The common urine drug test is also the easiest to beat.  There are more complex (expensive) urine drug tests that are harder to beat.  These are relatively rare and most often used to confirm a failed test when a contested, legal or financial ramification is possible.

How Long Do Drugs Stay In Your System for A Hair Drug Test?

Know how long do drugs stay in your system for a hair drug test.  The hair drug test can detect drug usage in any hair that was growing anywhere on your body at the time you used the drug.

Example:  If you used 12 months ago the hair growing at that time is still on your body, it can be detected.  

The hair drug test can also tell when and how much of a specific drug was used.  However, these specific hair drug tests are rare.

How Long Do Drugs Stay In Your System For A Mouth Swab Saliva Drug Test?

Know how long do drugs stay in your system for a saliva drug test. The saliva drug test ( also known as Mouth Swab Drug Test) can be given anytime, anywhere.  The results are accurate and immediate.

The saliva drug test is not affected by the standard “tricks” used to beat the urine drug test.  Because of these advantages, the saliva drug test is replacing the urine test.  The saliva drug detection times are generally shorter than the urine test.

How Long Do Drugs Stay In Your System For A Blood Drug Test?

Know how long do drugs stay in your blood for a blood drug test.  The blood drug test is very accurate, is the least used and must be administered by a heath care professional.  It is the gold standard of drug testing.  The blood drug test most often given by insurance companies or law enforcement.  

NOTE:  Expect a urine drug test with the blood test.  This combination provides both a short and long-term look at your drug exposure.


 

What Can Affect How Long Do Drugs Stay In Your System?

A drug test does not look for the actual drug in your system.  It looks for something called a metabolite.  When you ingest a substance your body changes (metabolizes) that substance into one or more metabolites.  It is these metabolites the drug tests looks to identify.  Any metabolites your body does not use are stored off in the fast growing cells such as hair, nails and to the greatest degree your fatty cells.  The more fat in your body the longer the drug detection times tend to be.

how long do drugs stay in your systemThe problem is that an exact timetable for how long drugs remain detectable is almost impossible to exactly determine due to the many factors that can affect how an individual’s body processes and stores metabolites of the drugs.  Most tests are also available with various cut off  levels which can increase or decrease your drug detection times.  As an example, the amphetamine drug test is available in cut off levels from 500 to 1,000 pg/mg with corresponding longer detection times as the cut off level gets higher.

To be safe, Always Test Clean publishes the maximum time a drug can be detected with the most sensitive tests.  Even though there are some standards for drug cut off levels, one rarely knows the sensitivity level of the test faced.  Betting on the lower (minimum) time can get one into real trouble.  Many other charts profess minor differences in drug detection times.  We believe in publishing clearly safe lengths of time.  These drug test detection times are your number one bet on being safe.

Drug Detection Times Can Vary Substantially Based Upon:

  • Amount and Frequency of Use:  Single or small doses of drugs are generally not as detectable for as long a period of time as chronic or long-term use.
  • Metabolic Rate: Individuals with slower body metabolism are prone to a longer detection times.
  • Body Mass: In general, human metabolism slows with increased body mass resulting in longer detection time.
  • Physical Activity: Physically inactive individuals with a high percentage of body fat in relation to total body mass are prone to a longer detection time due to the increased amount of excess metabolites stored in their fat cells.
  • Age:  In general, human metabolism slows with age.
  • Overall Health:  Human metabolism slows during periods of bad health which can result longer drug detection times.
  • Drug Tolerance:  Users typically metabolize a drug faster once a tolerance to the drug is established.  This can result in a shorter detection time.
  • Urine pH: Urine pH can impact drug detection.  A highly acidic urine results in a somewhat shorter detection time.

Note On The Drug Detection Time For The Hair Drug Test.

The hair sample can be taken from anywhere on your body.  Shaving your head won’t work.  The hair drug test sample is usually taken as close to the scalp as possible and is about 1.5 inches long giving a drug detection time of about 90 Days.  Should the tester take 2 inches of hair your drug detection time will be extended an additional 30 days.  Drug use can be detected for many months or even years in your hair is long enough.

Note On The Drug Detection Time For The Blood Drug Test.

A blood drug test looks for the presence of the actual drug in your blood.  The blood drug test is most often used to determine the presence of current health issues such as nicotine, diabetes, HIV/AIDS, cholesterol levels, hepatitis and other things of concerning overall health.  Most drugs have a detection period of less than 2 days.  The exceptions are THC and Nicotine, which chronic use can be detected for several weeks.  The blood drug test is often given along with a urine drug test, so be ready for both.

 

Drug Detection Times Chart

Do Not Base Your Outcome On Just Anyone’s Published Drug Detection Times.

As stated above, absolutely accurate drug detection times are a myth.  Drug test detection times do vary based upon some factors that are in your control and some factors that are out of your control.  But one has to have a base line to begin.  Judging your drug detection times is difficult at best.  If you really want the least risk to pass a drug test, you should either not do drugs or rely on the technology of detoxification for reliable results.

These Drug Detection Times Are Worse Case.

The drug detection times below are based upon a worst case scenario. This is why these times might be a bit longer than some published times.  As you can imagine,it would not be prudent to base your decision on the shortest time drug detection times published.  The drug detection times we publish are not only based upon worst case times published by across the major drug test manufacturers, but by real world experience over the past 20 years.

These Drug Detection Times Are Safe To Use.

We have included drug test detection times for most of the prescription and non-prescription drugs most will be facing.  We have included these times across all four of the major drug test mediums; urine, hair, saliva and blood.
