What Happens When You Mix Weed and Coffee?

To enhance a cannabis high, enthusiasts often mix weed with coffee. This combination—also known as a Seattle Speedball—blends the relaxing, psychoactive effects of THC with the stimulating properties of caffeine, providing an energizing and enjoyable start to the day. 

But have you ever wondered what happens when you mix cannabis and coffee? Is coffee and weed a good combo? In this article, we’ll explore how weed can interact with caffeine and the effects of mixing the two. Let’s get into it!

What happens when you mix weed and coffee?

Cannabis and caffeine both affect our bodies differently. Caffeine is a stimulant that increases alertness and boosts energy by blocking adenosine receptors in the brain. 

In addition, it also stimulates the release of dopamine, a feel-good hormone made in the brain that plays an important role in the brain’s reward system.

Cannabis also acts as a stimulant. Its effects can vary and largely depend on the cannabinoids like CBD and THC. CBD has non-intoxicating properties and is known for providing relaxation and pain relief. While THC is a psychoactive compound responsible for altering cognition, perception, and mood. Many enthusiasts prefer Cannabis Flowers, the purest form of Cannabis Flowers, to experience natural effects more clearly.

Anecdotal evidence shows that combining these two substances may boost energy and focus, and promote relaxation. Some research also found that consuming THC and caffeine together might make your high more pleasurable. 

Caffeine is believed to enhance the effects of the high or cancel out the effects of cannabis. However, it depends on the terpenes and cannabinoids found in cannabis, dosage, individual tolerance levels, and your body’s response to caffeine and cannabis.

What are the effects of mixing weed and coffee?

There is no evidence to support that cannabis and coffee counteract each other. Mixing coffee and weed can result in a range of effects. Some users report that mixing a small amount of THC with coffee enhances the effects of the high, while some might feel more anxious or jittery.

Other reported effects of combining these two include improved focus, a mellow high with enhanced alertness, a boost in energy without the jitters of caffeine, reduced grogginess from THC, and improved working memory.

    FAQs

    Are there risks to mixing caffeine and cannabis?

    There are no reported extreme risks when mixing coffee and cannabis, but the effects of combining the two can vary from one person to another. This is because the effect of cannabis coffee depends on the strain type, individual tolerance level, and body type. Adding a cannabis strain with a higher concentration of THC can lead to unwanted symptoms like paranoia and anxiety.

    Can you use a coffee grinder for weed​?

    Yes, you can use a coffee grinder for weed since they are essentially the same device as cannabis grinders. However, cannabis residue can affect the flavor of your coffee if the grinder is used without cleaning after use.

    What are the best strains that pair well with coffee?

    Gelato and Lady Bird Kush are the best choices if you are using slightly darker roast coffee and want to amp up the sweetness. The sweet, fruity notes of Runtz pair well with darker roast coffee, making your darker brew more flavorful. Super Lemon Haze has citrusy notes that complement the light roast coffee.
