Summary

This study will test a new visual scale designed to help people who use methamphetamine estimate how much they use each day. Researchers will compare the scale's results with hair samples and other methods to see if it is accurate and easy to use. About 100 people aged 20-40 who use methamphetamine will participate. The goal is to improve how we measure drug use in research and clinical settings.
