How cannabis and alcohol together affect impairment
The Impact of Cannabis Route of Administration and Co-Administration of Alcohol on Impairment
This study is looking at how using cannabis in different ways—like smoking, eating, or vaping—affects your ability to think and react when you also drink alcohol, so we can better understand the risks for people who drive or work while using these substances.

What this research studies
This research investigates how different methods of consuming cannabis, such as smoking, eating, or vaping, affect impairment when combined with alcohol. It aims to understand the acute effects of these substances on psychomotor skills, attention, and cognitive functioning, which are crucial for safe driving and workplace performance. The study will involve human participants in controlled laboratory settings, using rigorous methods to ensure reliable results. By comparing the effects of cannabis consumed in various forms alongside alcohol, the research seeks to provide insights into the risks associated with their concurrent use.
Who could benefit from this research
Good fit: Ideal candidates for this research are adults who use cannabis and alcohol, particularly those who may consume them together.
Not a fit: Patients who do not use cannabis or alcohol, or those with severe cognitive impairments that prevent them from participating in the study, may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to better guidelines and interventions to reduce accidents and improve safety for individuals who use cannabis and alcohol.
How similar studies have performed: Previous studies have shown significant impairment effects from cannabis and alcohol, but this research is novel in its focus on different cannabis consumption methods.
