The present invention relates to an online mind-altering substance testing system. The system includes distributed mind-altering substance testing units for performing mind-altering substance tests. A server is provided for receiving results of the mind-altering substance tests. A database is provided for storing the results. A display is provided for displaying the stored results, preferably in a dashboard of graphs to facilitate rapid and intuitive evaluation of often large numbers of tests from various testing units. Advantageously, a reviewer may review live stored results from multiple testing units once the tests have been performed, which enables rapid risk assessment and corrective action to be undertaken. For example, the effect of failed tests may be more frequent at a certain site prompting a need for investigating a cause at that site.
