Summary

This study looks at how alcohol and cannabis, alone or together, affect driving ability and thinking. About 40 occasional cannabis users who also drink alcohol will use a driving simulator after taking controlled doses. The goal is to understand the risks of driving under the influence of these substances.

What this could lead to
