How Long Does Adderall Stay in Your System?

AUDIO

 
Wondering how long does Adderall stays in your system for a drug test? This question is sometimes made by users that are subject to tests for their job or probation.

It comes in both immediate release tablets or capsules and extended release form. There is a big difference in the time Adderall stays in your system and detectable in the urine.

The answer to this question varies for any specific individual, based primarily on body weight and how much Adderall was taken over time. Adderall detection in body fluids is primarily dependent on:

  • body weight
  • metabolization rate
  • amount ingested
  • how long taking it

There are general guidelines that will prove true most of the time. Whether this amphetamine can be detected by a drug test depends on the type of test.

How long does it take to get off Adderall?

Adderall is detectable in the bloodstream for a different amount of time than it is in urine. Immediate release Adderall can be detected in urine for about 48 to 72 hours. Extended release could remain in the blood for up to four days, or approximately 96 hours.

Amphetamines are detectable in the urine for at least 3 days to 4 days (72 to 96 hours) and sometimes longer. This can vary with dosage, weight, and diet, which means a good conservative rule of thumb is they are detectable for up to four days. For heavy Adderall users, increase the amount of time.

Half-Life Biometrics

Dextroamphetamine (Adderall) has a half life of approximately 10 hours. This means that after 10 hours, the amount of this drug in your body has been reduced by half.

Example

By doing the math, you can figure approximately when all of it should be out of the body. For example, if someone took 30 mg of Adderall at noon today;

– at 10 PM there would be 15 mg in the body.

Tomorrow
– 8:00 AM the next day, it would be down to roughly 7.5 mg

– 6:00 PM ~ 3.75 mg

2 days later

– 4:00 AM two days later there would be about 2.0 mg

– 2:00 PM about 1 mg

– 12:00 AM .5 mg

3 days later

– 10:00 AM .25 mg

– 8:00 PM ~.125 mg

4 days later

6:00 AM ~ 0.06 mg
4:00 PM ~ 0.031 mg

5 days later

2:00 AM 0.016 mg
12:00 PM 0.007 mg

8:00 PM -gone

In this example, it took 4/12 days to clear all the Adderall out of this person’s body.

Blood Tests

For occasional users, blood tests usually are unable to detect amphetamines after approximately one day. Heavy users systems need more time to metabolize all of it.

If you are a drug addict who simply slipped once, or took Adderall for a legitimate reason, there are ways to avoid testing positive. The best method is time. If you can schedule your drug test for a later day, you are more likely to come up clean. Also, as previously noted, if you have the option of a blood test or a urine test, the former is less likely to show amphetamine usage after a day.

Does drinking water help flush Adderall?

Amphetamines are water soluble, which means that you can literally sweat much of it out of your body. If you are concerned about a drug test, you can drink lots of water and engage in heavy physical activity. This won’t clear your system completely, but it will help speed the removal of amphetamines from your system.

Treatment

While it is important not to let a single drug test ruin your life, it is also important to be drug free. Even if you do manage to pass a drug test, if you have an Adderall addiction, you should seek assistance to end the addiction as quickly as possible.
