Trying to determine exactly how long amphetamine is detectable in the body depends on many variables, including how frequently it has been taken, how much was taken, and the person's metabolism, body mass, age, and overall health. Prescription amphetamines come in different strengths as well as immediate and extended-release forms, which can impact how long it takes for your body to metabolize the drug.
For example, a 5mg dose of Adderall will have a shorter detection time than a 5mg dose of Adderall RX the extended-release form. Your liver and kidney function can play a role in how long it takes for your body to excrete amphetamine. People with decreased hepatic or renal function may eliminate amphetamine more slowly. People who use amphetamine very frequently or as prescribed by a doctor will have longer detection times than those who use the drug one time. People with high metabolisms process and excrete amphetamine more quickly than those with a slower metabolism.
Your metabolic rate can be affected by age, activity level, and overall health. The method by which you take amphetamine—swallowing, snorting, smoking, or injecting—also influences detection time. In general, the faster the drug is absorbed into the bloodstream, the shorter the detection window, so if you smoke or inject amphetamine, it will leave the body faster than if you snort or swallow it.
While many people try to sweat out or flush out amphetamines from their systems, the only proven way to clear your body of the drug is to discontinue use and to give your body the time it needs to metabolize and eliminate it. One reason that it is important to know how long amphetamine remains in your system is because of the risk of overdose.
If you or someone you love is prescribed a long-acting amphetamine, like Adderall RX, be sure to always swallow capsules whole; they should never be chewed or crushed, as this could release all the medication at once and increase your risk of overdose.
