The Connection of Coffee and Cannabis


Have you been reading reviews of the highest rated grow lights so that you can cultivate cannabis at home? If it’s legal in your state, why not try gardening right? If you’re a fan of recreational marijuana, you’ve probably heard about its unclear relationship with coffee.

Questions like “Does coffee improve my high?” and “Will I crave for more weed if I drink coffee?” might’ve already crossed your mind. And this is where we come in to explain.

Caffeine + THC: A Perfect Combination or Not?


According to Dr. Scott Krakower, the assistant chief of psychiatry at Zucker Hillside Hospital in New Hyde Park, New York, the combination of THC (the main active ingredient in cannabis) and caffeine may deteriorate a person’s working memory. Dr. Krakower says there’s a problem with their merging because caffeine is a stimulant, while marijuana is a depressant. When combined, they might make you feel tired and wired simultaneously. He also clarifies that caffeine won’t cancel out the “high” caused by cannabis. It’s also wrong to thing that you could get high and then sober because of caffeine.

The Craving Issue

Apparently, a study conducted in 2014 by scientists found that the more caffeine you take, the more you’ll crave for cannabis. In the experiment, scientists used squirrel monkeys as test subjects and gave them 1mg of MSX-3, a form of caffeine. During the entire test, the monkeys were given unlimited access to THC. In the first portion of the test, the monkeys had low cravings for THC.


However, when the scientists started increasing the milligrams gradually (like 3mg of MSX-3), they found that the monkeys craved for more THC.

This doesn’t mean the case would be the same with humans because after all, we’re a lot different from the test subjects. However, the possibility exists. The experiment also reveals that THC and caffeine resemble in terms of addiction. Clearly, we need to conduct more experiments regarding this matter.

Improving the “High”


Contrary to what most people believe, drinking coffee while smoking weed doesn’t enhance the user’s state of “high.” Studies haven’t been enough to support this claim. What research suggests, however, is that caffeine can enable the user to consume less pot while keeping one’s “high.” This is possible because coffee is augmenting the chemical effects in the user’s brain, making the “high” last longer. Drinking coffee may not be able to improve one’s high, but it sure can help you save more cannabis by lengthening your high time.


The connection of coffee and cannabis requires further research. But with the increase of technology along with marijuana being a hot topic these days, it’s only a matter of time before we can get our hands on complete information.
