How Long Does 30 mg Adderall Stay in Your System?

Are you wondering how long 30 mg Adderall stays in your system? Whether you’re taking it for medical purposes or recreational use, it’s essential to understand the duration of its effects and how long it remains detectable in your body.

The Half-Life of Adderall

Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine. It is commonly used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. The half-life of Adderall can vary depending on several factors, including your metabolism, age, liver function, and dosage.

The half-life of a drug refers to the time it takes for half of the substance to be eliminated from your body. For immediate-release Adderall, the average half-life is around 9 to 14 hours. This means that after taking a 30 mg dose, it may take approximately 9 to 14 hours for half of the drug to be eliminated.

Duration of Effects

The effects of Adderall typically last longer than its half-life. After taking a 30 mg dose, you can expect to experience the effects for approximately 4 to 6 hours. However, the duration may vary from person to person.

It’s important to note that the effects of Adderall can vary depending on the individual. Some people may experience a more prolonged duration of effects, while others may metabolize the drug more quickly, resulting in a shorter duration.

Drug Testing and Detection

If you’re concerned about drug testing, it’s crucial to understand how long Adderall can be detected in your system. Adderall can be detected in various types of drug tests, including urine, blood, saliva, and hair tests.

In urine tests, Adderall can typically be detected for up to 2 to 4 days after the last use. However, in some cases, it may be detectable for longer periods, especially with chronic use or higher doses.

In blood tests, Adderall can be detected for a shorter duration, usually up to 24 to 48 hours after the last use.

Saliva tests have a similar detection window as blood tests, with Adderall being detectable for approximately 24 to 48 hours.

When it comes to hair tests, Adderall can be detected for a more extended period. It can be detected in hair follicles for up to 90 days after the last use.

Factors Affecting Elimination

Several factors can influence how long Adderall stays in your system. These factors include:

  • Metabolism: Individuals with a faster metabolism may eliminate Adderall more quickly.
  • Dosage: Higher doses of Adderall may take longer to be eliminated.
  • Frequency of use: Chronic use of Adderall may result in a longer detection window.
  • Overall health: Liver and kidney function can affect the elimination of Adderall.


While the half-life of 30 mg Adderall is approximately 9 to 14 hours, its effects may last for 4 to 6 hours. The duration of detection in drug tests can vary depending on the type of test, with urine tests typically detecting Adderall for up to 2 to 4 days. However, it’s important to remember that individual factors, such as metabolism and overall health, can influence the elimination of the drug.

If you have any concerns about Adderall usage or its detection in drug tests, it’s always best to consult with a healthcare professional who can provide personalized advice based on your specific circumstances.
