If you've recently taken a urine drug test that targeted marijuana use, please complete the following form. If you plan on or are scheduled to take a drug test, please come back and let us know how it went. The information you submit will be used in order to increase the accuracy of our Marijuana Drug Test Calculator and be used when we periodically update our Data Analysis page.

Important:
When measuring the circumference of your waist, it is essential that you take the measurement at your belly button. The size of your pants is not a waist measurement and may skew the accuracy of our calculations. It's best to use a tape measure. However, a regular ruler, a piece of string, and some basic math skills will be adequate. If you lack a piece of string, be creative! This project can't happen without you.
