Alcohol and cannabis use behind the wheel: A deadly double risk
March 10, 2023

Driving under the influence of alcohol or cannabis is incredibly dangerous and can result in devastating consequences. When combined, the risk is even greater.
Alcohol is a depressant that slows down the central nervous system, causing impaired judgment, reduced reaction time, and decreased coordination. These effects make it difficult for a driver to react quickly and accurately to changing road conditions, potentially leading to accidents.
Similarly, cannabis can impair judgment, coordination, and reaction time, making it risky to drive while under the influence. Studies have shown that cannabis use can impair driving ability, including lane positioning, reaction time, and attention span.
When alcohol and cannabis are used together, the effects can be even more dangerous. The combination can lead to extreme impairment and an increased likelihood of accidents. A study published in the journal Accident Analysis and Prevention found that drivers who used both alcohol and cannabis were more likely to engage in risky driving behaviors and were at a higher risk of being involved in a car crash than those who used only one of the substances.
In addition to the risks of accidents and injuries, driving under the influence of alcohol or cannabis can lead to legal consequences, including fines, license suspension, and even jail time. It’s essential to never drive under the influence of any substance, and if you plan to consume alcohol or cannabis, make sure to arrange for a safe and sober ride home.
Substance use and driver behavior
Substance use can significantly impact driver behavior, making it dangerous to operate a vehicle while under the influence. Here are some of the ways substance use can affect driver behavior:
- Impaired judgment: Alcohol and drugs can impair a driver’s judgment, making it difficult to make sound decisions while driving. This can result in risky driving behavior such as speeding, running red lights, or making sudden lane changes.
- Decreased coordination: Alcohol and drugs can also decrease a driver’s coordination and reaction time, making it challenging to control the vehicle and respond to unexpected situations on the road.
- Increased risk-taking: Substance use can lead to an increased sense of confidence and risk-taking behavior, which can be especially dangerous while driving. This can include driving at excessive speeds or attempting to perform dangerous maneuvers.
- Reduced awareness: Substance use can impair a driver’s ability to pay attention to their surroundings, making it difficult to notice other vehicles, pedestrians, or obstacles in the road.
Overall, substance use can significantly impair a driver’s ability to operate a vehicle safely and responsibly. It’s essential to never drive while under the influence of alcohol or drugs and to arrange for a safe and sober ride home if you plan to consume these substances.
Daily alcohol and cannabis use
Daily alcohol and cannabis use can have significant negative effects on a person’s health and well-being, as well as their ability to function in daily life.
Alcohol:
Daily alcohol use can lead to alcohol dependence, which is a chronic and progressive disease characterized by the inability to control drinking, despite negative consequences. Long-term alcohol use can also lead to liver disease, high blood pressure, heart disease, stroke, and other health problems.
Daily alcohol use can also impact a person’s mental health, increasing the risk of depression and anxiety, as well as impairing cognitive function and memory.
Cannabis:
Daily cannabis use can also have negative effects on a person’s mental health, including an increased risk of anxiety, depression, and psychotic symptoms.
Long-term cannabis use can also lead to respiratory problems, such as chronic bronchitis, and can impair memory and cognitive function.
Both alcohol and cannabis can also impact a person’s ability to function in daily life, including their performance at work or school and their ability to maintain healthy relationships. Daily use can also lead to addiction, which can make it challenging to stop using these substances, even if they are causing harm.
It’s important to remember that any substance use carries potential risks and to use these substances in moderation, if at all. If you are struggling with substance use, it’s essential to seek help from a medical or mental health professional.
