A common question that Adderall users ask is how long the drug will remain in their system after use. This question is usually made by users that are subject to drug tests for their job or users of Adderall who are also on probation. The answer to this question varies for any specific individual, based primarily on body weight and how much Adderall was taken. Thus, while it is impossible to provide a precise answer to the question, there are general guidelines that will prove true more often than not.
Average Length of Time Adderall Stays in Your System
Asking how long Adderall will stay in your system is a tad too unspecific, because there are two different answers that matter to that question. Adderall, or more specifically the dextroamphetamine that is found in Adderall, is detectable in the blood stream for a different amount of time than it is in urine.
Dextroamphetamine has a half life of approximately 10 hours. This means that after 10 hours, the amount of dextroamphetamine in your body is half what it previously was. Thus, if you took 30 mg of Adderall, 10 hours later 15 mg will be in your body. Ten hours after that it will be down to roughly 7.5 mg. And ten hours after that it will be down to roughly 3.75 mg.
Whether this amphetamine can be detected by a drug test depends highly on the type of test. A urine test is able to detect lower amounts of the substance in your body than a blood test can.
For a urine test, you will usually test positive for an amphetamine until approximately 5-6 half lives have passed, or roughly 2-3 days. This can vary with dosage, weight, and diet, which means a good conservative rule of thumb is that it is detectable for up to four days. If you are a frequent user, the time scale is roughly doubled.
Blood tests are not able to detect amphetamines as well as urine tests.
For occasional users, blood tests usually are unable to detect any trace levels of amphetamines after approximately one day. Again, for frequent users, the time scale is roughly doubled.
Avoiding a Positive Drug Test
The best way to avoid a positive drug test is simply not to take a proscribed drug in the first place. It is safer and a sure-fire way to always test negative. If you are a frequent user, you may avoid a positive result on a test or two, but no amount of subterfuge will avoid a positive test for any extended length of time.
However, if you are a past addict who simply slipped once, or took Adderall for a legitimate reason, forgetting that such use was proscribed by your job, there are ways to avoid testing positive. The simplest way 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.
Finally, amphetamines are water soluble, which means that you can literally sweat them 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.
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.
