How to use this tool?
This calculator estimates the concentration of amphetamine in urine based on dosage, time, pH, and body weight. Follow these steps:
- Enter Dosage (mg): Input the amount of Adderall taken (e.g., 20 mg). Must be a positive number.
- Enter Time Since Last Dose (hours): Provide the hours elapsed since the last dose (e.g., 12). Can be 0 or more.
- Enter Urine pH (4.5–8.0): Input the urine pH value (e.g., 6.5). Must be between 4.5 and 8.0.
- Enter Body Weight (kg, optional): Optionally provide weight in kilograms (e.g., 70). If omitted, a default of 70 kg is used.
- Click "Calculate": The estimated urine concentration (ng/mL) will appear, along with a step-by-step breakdown of the formula.
Note: All inputs must be in metric units (mg, hours, kg). The result is for educational purposes only and should not be used for medical decisions.

Frequently Asked Questions
This calculator provides an educational estimate of amphetamine concentration in urine based on pharmacokinetic principles. It should not be used for medical or legal decisions.
The estimate is based on simplified pharmacokinetic models and population averages. Actual levels can vary significantly due to individual metabolism, hydration, and other factors.
Amphetamine excretion is pH-dependent. Acidic urine (low pH) increases excretion, while alkaline urine (high pH) decreases excretion, leading to higher concentrations.
