The existing drug testing methods such as through blood and urine pose problems on having errors in testing results due to contamination of samples. Also the existing methods has a time consuming process. A novel method of drug testing is devised through pupil's dilation. A sensor will measure the distance, which will vary the light. Light will constrict the pupil, while it is scan by camera. The image taken will be process by a single board computer. And the result will be shown on LCD. The device is a portable with an accuracy of 95 pcnt above and will determine the result with in less than 5 minutes
