Can You Mix Alcohol and Cannabis?
- Fact-checked by Dr. Desiree Granados
Mixing alcohol with cannabis is a subject that requires a nuanced discussion. Despite their prevalence in social settings, the effects of combining these substances are often misunderstood. In this blog, we’ll delve into what the latest research tells us about mixing these substances and the risks involved with doing so.
Whether you’re a socialite, a curious bystander, or a health professional seeking to offer evidence-based advice, understanding the dynamics of combined alcohol and cannabis use is more important than ever in an era of shifting legal landscapes and cultural norms.
What Happens When You Mix Weed and Alcohol?
What Happens if You Drink Alcohol Before Using Marijuana?
Consuming alcohol before using marijuana can amplify the effects of the weed. Alcohol increases THC absorption in the bloodstream, heightening the psychoactive impacts of marijuana and potentially leading to more intense feelings of disorientation or paranoia.
Generally known as a “crossfade,” this drug combination can lead to increased impairment and a greater risk of experiencing side effects like dizziness, nausea, and vomiting.
What Happens if You Use Cannabis Before Drinking?
When cannabis is used before drinking alcohol, it can decelerate the escalation of your blood alcohol levels, which can reduce or delay the sensation of drunkenness. This can cause you to misjudge your level of intoxication, potentially leading to riskier decision-making.
Moreover, THC can amplify the sedative effects of alcohol, increasing feelings of drowsiness and impairing motor skills more significantly than when either substance is consumed alone.
What Are the Dangers of Mixing Alcohol and Marijuana?
Mixing alcohol and marijuana heightens the risks associated with each substance. The combination can lead to a greater level of impairment, resulting in poor judgment, coordination, and reaction times. This can be particularly dangerous when operating vehicles or machinery.
Additionally, the concurrent use of the substances has been shown to amplify the effects of marijuana, leading to increased odds of anxiety, paranoia, and nausea. Crossfading is also associated with overconsumption of alcohol, a greater risk of overdosing, and, when done frequently, an increased risk of developing a serious mental illness.
Can Combining Alcohol and Cannabis Lower Your Level of Impairment
Contrary to some misconceptions, combining alcohol and cannabis does not lower your level of impairment. In fact, it has the potential to significantly increase it. Alcohol is a depressant, which slows brain functioning and neural activity, while cannabis effects can include altered senses, mood changes, impaired body movement, and difficulty with thinking and problem-solving.
When taken together, these substances can interact in unpredictable ways and often exacerbate each other’s effects.
Does Alcohol Affect Edibles?
Alcohol can indeed affect the experience of consuming cannabis edibles. When alcohol is present in the bloodstream, it can increase the absorption rate of THC into the blood. This can intensify edibles’ effects, which may catch users by surprise.
Additionally, combining alcohol with cannabis edibles can increase the potential for adverse reactions such as nausea, dizziness, and impaired judgment. Caution should be exercised when mixing the two, and it’s generally recommended to consume them separately.
What Should You Do if You Have a Bad Reaction with Alcohol and Cannabis?
If you experience a bad reaction when using alcohol and cannabis together, it’s crucial to stop consuming both substances immediately, seek a safe, calm environment, and hydrate. If you experience symptoms of an alcohol overdose such as difficulty breathing, a slow heart rate, loss of consciousness, or seizures, you should seek medical attention straightaway.
Avoid being alone and inform someone you trust about your condition. Remember, mixing alcohol and cannabis can amplify the effects of both, so moderation and awareness of your personal limits are essential.
