Adderall Levels in Urine Calculator
Estimate an illustrative single-dose curve for free.
The calculator and chart are free. This illustrative model cannot predict individual urine concentrations or test outcomes.
How to use this tool
Enter a dose, the hours since it was taken and a body weight. Tap the chart or move the time slider to read the curve at any hour. Comparing scenarios, saving and exporting are Pro tools. A scenario is a separate illustration, not an additional dose.
Your scenarios
Pro compares up to 12 scenarios on one chart.
Edit scenario
These are model assumptions, not measurements of your metabolism.

Understand the model
This tool preserves a simplified single-dose exponential decay model: initial level = dose × 1000 ÷ (weight in kg × 0.15); level over time = initial level × exp(−ln(2) × hours ÷ half-life). The starting level is an illustrative assumption, not a measured urine concentration.
The model does not account for repeated doses, formulation, urine collection conditions or individual clinical factors. Do not use the curves to determine test outcomes, change a prescription or infer a dose from a laboratory report.

Here for a drug test?
Pages 21–22 cover screening and confirmation, reporting cutoffs, prescription review, and why a urine concentration cannot reliably tell you the dose taken.
Most of the book covers general urinalysis: protein and uACR, blood, UTI markers, glucose, ketones, units, and comparing results. It is not an Adderall-specific guide or a way to predict passing a drug test.
- Learn why a screening result and a confirmed result answer different questions.
- Keep test names, units, collection details, and cutoffs in context.
- Use the glossary and question prompts to prepare for a follow-up conversation.

FAQ
- What is a high level of Adderall in urine?
- Adderall is a 3:1 mixture of d- and l-enantiomers of amphetamine salts. Peak amphetamine concentrations in urine have been reported around 2,645–5,948 ng/mL after a single therapeutic dose. Samples at or above 500 ng/mL of amphetamine (a common GC-MS confirmatory cutoff) have been observed up to about 47 hours post dose. Results vary by dose, metabolism, hydration, and urine pH.
