Can coffee get you high? (+3 considerations)

In this brief guide, we will answer the question, can coffee get you high? We will discuss how and why coffee gets you caffeine-high. We will also discuss the positive and negative effects of drinking coffee as a stimulating drug.

Can coffee get you high?

Coffee can get you high, as it is a stimulating drug. Coffee gives your brain a boost because of caffeine compounds. Caffeine promotes adrenaline which gives the brain a rush. It also blocks the hormone called adenosine, making you perked up instead of sleepy. 

Coffee is a performance-enhancing drug, which improves physical and mental focus and delays fatigue. However, the chemical modification to the brain comes with the cost of caffeine crash, which causes tiredness, irritable and lethargy.

How does coffee get you high?

Coffee is known and consumed for its stimulating properties. Coffee has caffeine, chlorogenic acid, and tannins that promote mental function and increase productivity. If consumed in moderate amounts, coffee makes a person productive. Coffee has the highest amount of caffeine, among other sources such as soda, tea, and cocoa.

Coffee affects both the brain and the body and causes the associated physiological changes to the body. Habitual consumption of coffee makes the body attuned to the chemicals in the coffee; therefore, the effects become unnoticeable and negligible with time.

According to the FDA, the safe limit for coffee is 400 mg a day. You can drink 4 to 5 cups of coffee in a day. However, some people are more sensitive than others, owing to factors; such as genetic makeup, health, age, and nicotine habits. 

When you consume excess caffeine from coffee, soda, and energy drinks, a condition called caffeinism causes nausea, jitteriness, and light-headedness in individuals who are not accustomed to caffeine.

Getting high on caffeine is possible when you exceed your habitual dose. Exceeding your coffee dose by a cup or half can be helpful, considering you keep it under safe limits. However, still breaking your pattern of coffee consumption can have ill effects that your body is not accustomed to.

 A caffeine buzz could make you active and fight sleepiness but will not make you productive. A caffeine rush often causes scattered thoughts, inability to focus, and excessive talking. A caffeine high is not worth it as its downside can cause more loss than gain. In conclusion, the dosage of coffee to get you high is variable to a person’s tolerance. 

How can getting high on caffeine have a detrimental effect?

1.Mental Stress

The stimulating effect of caffeine lasts for a short while, after which it can cause some people to crash. A caffeine crash is identified by sudden fatigue and sleepiness.

Coffee can also cause anxiety. Caffeine blocks the chemical called adenosine that prevents fatigue. When you take caffeine in a high quantity, it causes fatigue and nausea.

According to the American Psychiatric Association, caffeine-induced anxiety disorder is one of the syndromes related to caffeine. Taking around 1000 mg of caffeine in a day can cause nervousness, jitteriness, and nausea.

Drinking multiple cups of coffee in a row can cause stress and rapid breathing. Even if you drink coffee habitually or occasionally, it affects the stress levels at the same level. As the neurons work at a faster pace, it also makes a person feel nervous, jittery, and dizzy.

2. Stomach Distress

High caffeine causes a lot of distress to the body and the brain alike. A boosted nervous system affects the colons and GI tract, causing a person to experience stomach discomfort. 

Coffee is an acidic beverage that is heavy on the stomach. Acidic foods can cause digestive problems like ulcers and heartburn. 

Coffee can trigger GERD symptoms in people who drink it regularly. Some people can experience painful gastrointestinal symptoms if they consume a large dose of caffeine. Some adverse effects of caffeine toxicity include diarrhea, nausea, acid reflux, and gas.


Drinking a higher amount of coffee can also cause insomnia. As coffee wards off your sleep, it will interfere with your sleep cycle, especially if you consume it later in the day. 

Every person’s sleep will respond differently to caffeine. Too much caffeine will take you long to fall asleep, regardless of the time of day you take it. 

On average, coffee takes five hours to wear off. In reiteration, an individual could take anywhere between a half-hour to nine hours. 

Drinking higher doses of coffee also cause frequent urination, muscle breakdown, and increased blood pressure. Therefore, sticking to your usual cup of coffee is a fine idea to prevent such effects.
