What Are Drug Detection Times?

Get your drug detection times for urine, hair, saliva and blood drug test.Drug Detection Times indicate a point in time after you last took a drug in which drug testing can reveal the presence of the resulting metabolites in your urine, hair or saliva.  The blood drug test looks for the actual drug in your blood.  

The drug detection time also reflects how long a drug can be detected in your system and that can range from hours to many months, depending on the drug test, on the drug involved  on the length of time you have been using and even on your personal factors.

Most drugs will generally appear in urine or saliva within 2 – 8 hours after use where blood drug tests are almost immediate.  Drugs can be detected in the hair on your head about 5 – 7 days after use.  Detection in your body hair take as bit longer to show up as body hair generally grows slower.

What Can Affect My Drug Detection Times?

The problem is that an exact timetable for how long drugs remain detectable in urine, blood and saliva tests is almost impossible to determine due to the many factors that can affect how an individual’s body processes or metabolizes drugs.  Also, the tests are 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 know the sensitivity level of the test you are facing.  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.

Please Note: Users may test positive longer than times shown below In a small percentage of cases.  This is most obvious in cases of long-term chronic abuse or individuals with significant body fat or individuals with health related issues resulting in abnormally slow body metabolism.


 

Drug Detection Times Vary Greatly Across The Internet.   Why?

Drug Detection Times For Drugs.

Many people providing data on drug detection times publish the times that best support their needs.  Most publish the minimum drug detection times to be safe from a legal and / or marketing standpoint. Often these times tend to be unrealistic and do not reflect the real world. There are too many factors that can affect the drug detection times such as your length and amount of usage, your body fat levels, your metabolism, your diet and many other factors.

At Always Test Clean we are concerned with you passing a drug test with the least amount of risk possible. We publish the maximum saliva drug test detection times. In most cases your drug detection time will be less than our published times. We feel that is the safe way to approach this issue with our users.

Note On The Drug Detection TIme For The Hair Drug Test:  The hair drug test detection time is usually About 90 Days.  A Hair Drug Test not only can detect specific drug usage, but also can provide information of quantity of drug consumed and even the historic pattern of drug use.  Drug use can be detected for many months or even years in the future under ideal circumstances.  An Example:  Head hair grows at about 1/2 inch per month.  If your follicles are over 12 inches long and you used drugs when the root end was growing, the Hair Drug Test would detect the usage that happened over 6 months ago.

Note On The Drug Detection TIme For The Blood Drug Test:  A blood drug test takes a look at your bodies contamination of the actual drug at the point in time of your test only.  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 up to one week.  The blood drug test is often given along with a urine drug test, so be ready for both.
