Tetrahydrocannabinolis (THC) is just one of over 100 cannabinoids, or compounds found in the cannabis plant. And THC, along with cannabidiol (CBD), are the two natural compounds you’ll see most often when researching medical cannabis. Although THC and CBD have many similar medical benefits, they can have different effects. The main difference is that THC can produce a ‘high’, while CBD doesn’t. And remember, whilst there is evidence to give a general idea of how both THC and CBD may react with the body, they can affect every individual differently. 

Both compounds interact with your body’s endocannabinoid system (ECS), a messenger and receptor system that is integral to homeostasis (the management of balance) within the human body. One of the core components of the ECS are the cannabinoid receptors, which includes CB1 and CB2. THC is chemically similar to your body’s endocannabinoids which is why it can interact with these receptors. And it’s why cannabis works so positively on so many different conditions.

THC is available for medical use in several forms, including as an oil. And, we go into a bit more detail on how THC Oil specifically works in the body here. But, what happens when you combine THC oil and alcohol? We’ll be exploring that below. 

What Happens When You Combine THC Oil and Alcohol?

Some studies have found that alcohol can increase the amount of THC your body absorbs, resulting in a much more intense high (when used recreationally) and some pretty unpleasant effects: 

  • Sweating
  • Dizziness
  • Nausea
  • Vomiting

A medical cannabis prescription is supposed to help you work towards improving your health. But, consuming THC oil with alcohol could do the opposite. And that’s exactly why we’d recommend avoiding mixing the two. 

A lot more research is needed around THC oil and alcohol's interaction, as there's not enough evidence to say for sure how taking both together could affect you. There have been a small number of studies, some of which are outdated, and most of which simply didn’t provide us with enough data. 

Some claim THC slows down the absorption of alcohol, which has the potential to be very dangerous. It means you could feel more sober than you actually are. Other studies showed the opposite. And when there isn’t enough evidence to prove whether something is safe or not, it’s always best to avoid it. 

Short-Term Effects of Mixing THC Oil and Alcohol

Just like with any other medication, there can be side effects when taking THC oil. But consuming THC oil with alcohol can change these risks, and even make them more likely. And this is probably because, like we’ve said, alcohol can make cannabis effects more intense. Some short-term effects of mixing THC oil and alcohol include: 

  • Nausea and vomiting
  • Intensified effects on mood and anxiety
  • Increased risk of dehydration

Side effects can vary from person to person, and you may not experience any at all. The best thing you can do is take your medication as prescribed. And this likely means avoiding alcohol. Also try to remember to stay calm, and stay hydrated. Drinking lots of water can work wonders for the body, and these short-term effects should only last for a few hours.

Long-Term Risks of Combining THC Oil and Alcohol

If you regularly combine THC oil and alcohol, it can lead to much more serious risks. So, again, you might want to think twice before mixing the two. The same applies here - a lot more research is needed! But we think it’s worth mentioning a few things. 

A 2017 study found that people who use THC oil and alcohol together end up consuming more of both regularly, which increases the risk of dependence on the two substances. 

A 2011 study found that people who regularly consumed cannabis, and combined it with alcohol for the study, had decreased cognitive performance. This is when our ability to think, remember, learn, reason and pay attention is reduced. These findings could suggest that long-term use of the two together can be associated with a bigger decrease in cognitive function, and changes in brain structure. Which is obviously not a good thing. 

But again - the above study was small, so it’s hard to determine results. 

How to Safely Use THC Oil and Alcohol

It’s safest to avoid an alcohol and THC combination when you can. Your clinician will always advise against it, as do we. But although we don’t recommend it, if you do find yourself under the influence of alcohol and THC oil, there are a few things you can do to remain as safe as possible. 

Remember that, like with anything, moderation is key. If you plan on drinking alcohol after consuming your medication as prescribed, maybe drink a little less than you normally would. Also consider spacing out consumption, drinking slower and leaving a bit of time between each drink. Keep in mind that alcohol may intensify the effects of THC, so limiting your intake, and moderating what you’re consuming is so important. Maybe have a soft drink or glass of water instead.

You know your body, and therefore you know your limits. If you start feeling ill, or like you’re losing control, stop consuming. Ask a trusted, sensible friend to take you home, or to head home with you - in a taxi or by walking if it's not far of course. And avoid dangerous activities - this one’s pretty obvious and applies whether you’re drinking alcohol with THC oil or not. 

Summary 

Alcohol and cannabis effects can change depending on how much of each you’re consuming. But due to a lack of research, and some evidence to suggest that the two together can increase intoxicating effects, we’d always strongly recommend avoiding mixing THC oil and alcohol. 

When purchased from a licensed clinic like Alternaleaf, you’ll be advised on the best way to consume your medication. Ultimately it’s always a good idea to follow what your clinician says. If you ever experience any issues with the way you react to your medication, stop, and speak to them. And we’re always here to help with any questions you may have.
