Ask an MD: Can I Take Edibles and Alcohol Together?

Combining cannabis and alcohol is not uncommon. While this combination is common, that doesn’t mean it’s always safe. 

While cannabis is generally considered to be safe when appropriate doses are taken, it's not possible to make claims about safety when cannabis is mixed with other substances.

To help us best answer questions about edibles and alcohol, we turned to Dr. Brian Kessler, NuggMD's Chief Medical Officer and Medical Director of Spine and Sports Medicine in Manhattan.

If you have questions about your individual health, consider reaching out to a medical professional who can provide you with specific, individualized advice. The information presented is not meant to replace medical advice but to simply share the current research.

What Are the Common Effects of Mixing Weed and Alcohol?

Combining alcohol and cannabis should be taken seriously, as it can have a variety of negative effects, including dizziness, nausea, and decreased motor skills. Research has found that this combination can also lead to higher rates of psychiatric concerns, as well as increased symptoms.

“Cross faded” is the term that’s often used when someone is under the influence of both cannabis and alcohol. When someone uses alcohol and cannabis together, they are more likely to use higher amounts of both than if they had used only one of those substances.¹

It is never a good idea to drink and drive or use cannabis and drive. 

Overall, “crossfading can be dangerous for some if care is not taken when consuming both THC and alcohol,” says Dr. Kessler.

If you plan to consume both alcohol and cannabis, do so with caution. When in doubt, avoid this combination to avoid unwanted or unpleasant effects.

How Does the Body Process Alcohol?

Alcohol is metabolized by several pathways in the body.

The liver is the organ that’s primarily responsible for processing alcohol. This is the primary reason why people who drink heavily may experience liver damage. Keep this in mind when consuming alcohol since moderation is key.

Is Weed Bad For Your Liver?

Edibles are metabolized by your liver. Dr. Kessler notes, “So far, the research we have does not indicate that THC causes damage to the liver in the same way that alcohol does, nor does it negatively impact individuals with preexisting liver conditions.”

Whether or not weed impacts your liver most likely depends on the method of consumption that you use. It is possible that edibles may impact your liver more than smoking cannabis could.² Like alcohol, the body has enzymes that break down THC.

An inhaled option may be a better choice if there are worries about the effects of weed on the liver. With that being said, there’s not a serious cause for concern. In fact, current evidence doesn't link edible use to liver damage.

What Are the Risks of Using Edibles and Alcohol at the Same Time?

“Using cannabis edibles and alcohol at the same time can lead to increased effects like dizziness and disorientation,” says Dr. Kessler. Dealing with these symptoms can be alarming and difficult to cope with.

Research has found that when people use weed and alcohol at the same time, higher levels of cannabinoids are found in blood samples. This is important to note, as many people don’t consider how this combination could affect their body’s metabolism and its ability to process these substances.

The same research found that alcohol has the ability to prolong the effects of cannabis. And since edibles already have a longer duration of effects, this can be especially uncomfortable for someone experiencing cross faded symptoms.

It’s always best to be safe and avoid risky combinations - including avoiding driving and using heavy machinery when combining cannabis and alcohol. 

Are the Effects of Edibles and Alcohol Different From Smoking and Alcohol?

The consumption method of cannabis could impact the effects that you feel.

Dr. Kessler explains, “Because edibles take up to two hours to process through the body and take effect, combining them with alcohol can lead to more intense effects once you begin to feel the edibles if you don’t watch your dose.”

It's important not to increase the edible dosage if the desired effects aren’t felt yet. It is better to wait to consume another edible on another day rather than taking an additional dose.

A person’s tolerance is another important factor. The level of tolerance that an individual has to both alcohol and cannabis can significantly impact the effects that they experience. Regular use of these substances may lead to experiencing fewer effects than a new user would.³ Regardless, this combination should be taken seriously, no matter your experience.

How to Help Someone Who is Cross Faded?

If you’re currently with someone who’s taken both weed and alcohol and they’re having a bad experience, there are a few different options to turn the situation around.

Firstly, assess the situation. Consider asking your friend what symptoms they're experiencing and ask them how you can help ease them. Consider recommending some methods to sober up from weed. Drinking water, eating a healthy snack, and getting some exercise can all be great ways to help the body cycle out the cannabis.

The effects of edibles can typically last six to eight hours, but this could be extended if alcohol is also added to the situation.⁴ This is important to remember, as you can remain calm if your friend is still experiencing symptoms a few hours later.

When helping someone who’s cross-faded and having a bad experience, remain cautious and calm. If you have serious concerns about your friend's safety, you shouldn’t hesitate to seek medical advice.

Overall, it's a great idea to monitor your friend’s symptoms and encourage them to make healthy choices (such as drinking water and eating).

Is There a Safe Way to Combine Edibles and Alcohol?

Some people use weed and alcohol, but Dr. Kessler recommends, “If you choose to combine edibles and alcohol, it is recommended to start with low doses and stay hydrated.”

To avoid adverse effects, one of the most important things to consider is the dose. Higher doses of both these substances increase the likelihood of having adverse effects. When in doubt, err on the side of caution and use a lower dose.

If you’re new to using edibles, it's best to avoid combining them with alcohol. Using edibles and alcohol could lead to more noticeable effects, including some unpleasant ones.

Another option, if deciding to combine edibles and alcohol, is to be around people who have used this combination before. These friends can guide you through the experience and help you understand it, especially if there are adverse effects or symptoms. 

What About Beverages That Combine THC and Alcohol?

“Products combining THC and alcohol are not legal, making these products a risk for users as they are not regulated and tested for safety,” notes Dr. Kessler.

These unregulated products can contain unknown doses of THC, increasing the risk of consuming too strong a dose. Staying away from these products is a good idea, especially if you’re unfamiliar with the source from which you’re purchasing them.

If deciding to combine edibles and alcohol, then it’s important to make sure that you keep the substances at a low dose and pace yourself. Remember that THC can take up to two hours to take effect, so it’s important to stay on the right track and not to overwhelm yourself.
