What Happens When You Smoke Weed and Drink Coffee?

The process of making the perfect cup of coffee can be a relaxing and therapeutic experience – where even just the scent of a fresh brew can provide an energizing lift.1 


Some will argue that the same could be said about rolling the perfect joint and enjoying the sweet scent of some quality cannabis. Perhaps this is why both coffee and cannabis have become so deeply entrenched in the daily lives of so many around the world.

As a result, many might wonder if the mix of caffeine and THC makes sense for them. To help answer that, let’s begin by exploring some of the history of coffee and cannabis. 

It Seems We Have Goats to Thank for Coffee

According to legend, coffee’s ability to boost mental alertness was first brought to the attention of humans in the 9th century CE. That’s when a goat herder in Ethiopia noticed that his goats became energized and didn’t want to sleep after eating red berries from a certain tree.

He reported his findings to an abbot at the local monastery who made a drink with these berries. The abbot noticed the drink helped him stay alert during the hours of evening prayer so he shared his experience with the other monks, and word about these berries quickly spread.2

History suggests that the Sufis of Yemen were among the first to enjoy coffee outside Ethiopia. They were said to have used coffee as part of their religious and mystic rituals.3

The History of Cannabis Goes Back 10,000 Years 

Cannabis was first domesticated in Central Asia more than 10,000 years ago (8,000 BCE). Its use for medicinal purposes can be traced back to 2737 BC. That’s when Emperor Sheng Neng of China was said to prescribe marijuana tea for the treatment of over 100 ailments including gout, rheumatism, malaria, and poor memory.4


Caffeine and THC

The combination of caffeine and THC has been enjoyed since at least 1972. That’s when the first coffee shop, the Mellow Yellow, opened up in Amsterdam. Since then, countless people have enjoyed the calming yet stimulating mix of THC and caffeine – and have come up with creative names for the mix, like Hippie Speedball.

In addition to providing a relaxing yet stimulating buzz, caffeine and THC may offer health benefits. But before we get to that, let’s go over how each can interact with our bodies and minds. 

How Do Caffeine and THC Impact Our Health? 


Caffeine and delta-9-tetrahydrocannabinol (THC) are both psychotropic substances.

Psychotropic substances can impact our behavior, mood, thoughts, and overall state of mind. Other examples of psychotropic substances include alcohol, nicotine, and prescription drugs.

Psychotropic substances have been known to have potential health benefits like helping to treat anxiety, depression, sleep disorders, and schizophrenia.

Although psychotropics like caffeine and THC may provide potential health benefits, they can also present serious side effects depending on things like the strength of the cannabis and coffee, your overall health, and medications you may be taking. 

The Effects Will Be Different for All

It is important to keep in mind that caffeine and THC are both natural compounds that will impact everyone differently. That is why it is always a good idea to speak with your doctor before introducing psychotropics into your repertoire.

With that said, here are a few of the effects and benefits each may provide.

Caffeine’s Effects:

  • Reduced fatigue & improved energy
  • Sharpened mental focus
  • Feelings of euphoria

Some of Caffeine’s Potential Health Benefits: 

  • Treating headaches and migraines
  • Lowering  the risk of diabetes
  • Improving endurance and athletic performance 
  • Reducing depression

THC’s Effects 

Although everyone’s experience with cannabis will be different, the effects of THC generally include:

  • Relaxation
  • Euphoria
  • A sense of calm

THC is just one of more than 100 cannabinoids in cannabis. Cannabidiol (CBD) is another. Although more research is needed, current studies suggest that THC, CBD, and other cannabinoids may be helpful in the treatment of a wide range of medical issues.

Cannabinoids like THC and CBD have Shown Potential in the Treatment of:

  • Cancer 
  • Glaucoma 
  • Pain and inflammation
  • Anxiety, depression, and PTSD
  • Symptoms associated with HIV
  • Seizures, particularly in children 
  • Alzheimer disease and other degenerative conditions

So what is it about cannabinoids that makes them so effective, where traditional medicine has failed? It could be that our bodies are built to thrive on cannabinoids. Learn more about Cannabinoids here.

Is the Mix of Coffee and Weed Bad?

Since coffee and cannabis may offer so many health benefits on their own, you might think it’s safe to assume that enjoying a little bit of weed with your coffee would be okay. The reality is … it might be safe for most, but not for all.  Here’s why.

THC and coffee can boost the amount of dopamine in our systems. Although dopamine can promote feelings of happiness and euphoria, too much of it at once can trigger anxiety, agitation, and paranoia.

In addition, both caffeine and THC can both increase your blood pressure and heart rate. 

Coffee and THC Can Be Dangerous for Some

This is why many doctors advise that those with heart conditions and those at risk of heart arrhythmia or stroke, should not mix caffeine and THC. So, if you’re new to mixing coffee and cannabis, it’s important to consult your doctor to make sure it makes sense for you. If it does, begin with lower amounts of coffee and cannabis than you would normally consume on their own. Then if needed, you can increase your dosage slowly.

Possible Benefits of Mixing THC and Caffeine

It is believed that mixing THC and caffeine may result in an enhanced cannabis experience – with benefits including:

  • Mental alertness
  • Improved energy
  • Feelings of relaxation, happiness, and euphoria

In addition to providing a relaxing effect to go with that caffeine buzz, pairing cannabis with coffee has also been said to help people reach a flow state. 

Caffeine + THC + Exercise = Flow State

A flow state is defined as an “optimal state of consciousness when our brains begin to quiet down, allowing for an increased sense of wellbeing, an elevated sense of energy, and a spiked increase in concentration.”5

Flow states are said to inspire creativity and boost mental and physical performance. 

Here’s some good news for those whose pre-workout routine includes a bit of THC and caffeine. The mix of THC, caffeine, and exercise has been said to help facilitate this flow state.

Another example of a beneficial mixture is the right combination of cannabinoids and terpenes. It’s believed that when you dial in the right mix of the two, it can result in an enhanced cannabis experience – with potential health benefits. This is known as the Entourage Effect.

How Does Caffeine Impact the Potency of Your Weed?

Back in 2014, a study was conducted to measure the effects of mixing caffeine and cannabis on squirrel monkeys. The results of this study were published in the Journal of Neuroscience.

The monkeys were given the ability to self administer cannabis whenever they wanted. All they had to do was to pull on a lever. When the monkeys were given low doses of a substance similar to caffeine, they seemed less likely to reach for the THC. But, when they received high doses of caffeine, they seemed to reach for that lever more often.6

Then in 2018, a study led by Marilyn Cornelis at Northwestern University’s Feinberg School of Medicine seemed to back up these findings. This time, the study examined the effects of mixing cannabis and coffee on humans. It found that the more caffeine people consumed, the less cannabis their body was able to metabolize.6

So, although small amounts of caffeine can help your THC go a long way – too much caffeine can lessen its effects.

What to Look Out for When Mixing Cannabis and Coffee

As we said earlier, coffee and THC will impact everyone differently. Since both can increase your heart rate and blood pressure, it is important to begin with lower amounts of coffee and cannabis than you would normally consume on their own. Then, if needed, you can increase your dosage slowly.

A Few Things to Keep in Mind:

  • Low levels of caffeine can help to maximize the effects of THC, but too much caffeine can lessen the impact of your cannabis 
  • The right mix of coffee and cannabis can promote creativity, a sense of wellbeing, and improved concentration – especially when paired with exercise
  • Caffeine and THC can both increase dopamine levels, but too much at once can trigger anxiety, agitation, and paranoia

It All Comes Down to Finding the Mix That’s Right for You 

Everyone’s experience with medicinal cannabis will vary. Instead of focusing on which strain to medicate with, it’s important to find the right balance of cannabinoids and terpenes that work best with your endocannabinoid system.
