Adderall has a half-life of 9 to 14 hours, which means that 9 to 14 hours after dosage, only half of the drug re in your body. Adderall will usually completely clear your system within 72 hours (or 3 days). However, the length of time in which Adderall stays in your system can vary based on several factors, particularly the drug test methodology being used.

How Long Does Adderall Stay in Urine, Hair, Saliva or Blood Samples?

Different tests detect Adderall within different timeframes:

  • In a urine test, Adderall can be detected for up to 4 to 7 days.
  • When testing hair follicles, Adderall can be detected about a week after use for up to 90 days.
  • In a saliva test, Adderall can be detected 20 minutes after use and can be detected for up to 48 hours.
  • In a blood sample, Adderall can be detected 12 to 24 hours after dosage and can be detected for 24 hours.

Does Adderall Show Up on a Drug Test?

Adderall use can be detected in urine, hair, saliva and blood samples within the detection windows. Each drug test uses different biological testing methods, so the overall detectability of Adderall in your system will vary widely.

Adderall Detection Windows

  • Urine testingAs with most types of drug testing, Adderall use can show in a urinalysis. The urine is tested for metabolites that the drug produces, which remain in the system longer than the drug itself. While most Adderall levels in urine are eliminated within 36-70 hours of use, urine could test positive for up to 4 days.
  • Hair testingHair testing involves collecting a hair sample from an individual and testing the hair follicles for Adderall’s metabolites. Hair testing allows for the longest window of time to detect drug use, up to 3 months. However, it often takes at least 1 week after use for metabolites to be present in hair follicles.
  • Saliva testingThough not common, saliva testing is occasionally used to detect Adderall use. Once taken from an individual, saliva is taken to a laboratory and analyzed for metabolites. Saliva testing is thought to be the quickest method to detect drug abuse, as Adderall can show up in saliva as soon as 20 minutes after use. It may remain detectable for up to 48 hours after use.
  • Blood testingAnother uncommon method of testing for drug use is testing the blood. This is an invasive type of testing. It also only offers a short window to detect the drug, typically only within 24 hours of use.Testing for Adderall misuse may be administered in several situations.
    • If authorities suspect misuse among students in an academic setting, testing is a possibility.
    • Some employers also administer tests to screen for the drug randomly or if use is suspected.
    • People with a criminal history who are on probation may also be tested from time to time.

Since the time it takes for the body to be clear of Adderall, and the timeframe depends on many factors, there is no clear timetable for how long it may take. Because it has a high potential for abuse and addiction, it should be used with care. If you believe that you cannot stop using Adderall, or are abusing your prescription, seek medical help.

What Factors Influence How Long Adderall Stays in Your System?

Many factors influence how long Adderall stays in your system, from body composition and dosage amount to frequency of use.

  • Body CompositionAdderall metabolizes more quickly in people with higher body weight. When people with a higher weight take the same dosage as someone who weighs less, a smaller amount of the drug is available in their bloodstream.
  • Food in the SystemFood does not affect the metabolism of Adderall, and it can be taken with or without food. However, it may not absorb into the bloodstream as well in acidic environments, like when the stomach is full of food.
  • PH levelsThe PH levels in the urinary and gastrointestinal tracts may affect how long it stays in the system. The kidneys will take longer to remove Adderall through the urine if someone has a high pH level (more alkaline). Also, things like food and drink can influence the body’s pH.
  • Organ functionOrgans such as the liver and kidneys play an important role in ridding the body of many substances, including Adderall. This process can be slower when an organ does not function as it is supposed to. If kidney function is not normal, the drug may remain in the system longer than normal or even be recirculated. The same goes for liver function. The liver plays a role in metabolizing substances in the body, so the process will slow down if the liver is not functioning as it should be.
  • Dosage amountA medication’s dosage can also greatly affect how long it takes to clear the system. As with any prescription drug, the more someone has taken Adderall, the longer it will take for the body to remove it from the system.
  • Frequency of useThose who have been using Adderall regularly or daily will likely take longer to clear it from the system compared to someone who has only used the drug a few times. When the drug is taken daily or frequently, it can accumulate in the body, making it take longer to leave the body entirely.

What is Adderall Prescribed For?

Adderall is the brand name for amphetamine salts, and it is a central nervous system stimulant. It most often used to treat attention deficit hyperactivity disorder (ADHD), a condition in which people have difficulty focusing or paying attention to a single task and act impulsively.
