Mixing Cocaine And Caffeine: Side Effects And Risks

Medically Reviewed by Johnelle Smith, M.D. on July 31, 2023

Cocaine and caffeine are often taken together, as much of the cocaine found on the street today is cut with caffeine. Both substances are, however, highly addictive and can increase your risk of developing an addiction or dependence to one or both drugs.

Dangers Of Mixing Cocaine And Caffeine

It is not uncommon to find cocaine and caffeine used together because caffeine is a common filler in cocaine that is sold on the street.

Caffeine is legal and found all over the world in coffees, teas, and energy drinks. It is not usually dangerous unless taken excessively.

But when mixed with cocaine it can produce a risky and potentially dangerous combination.

Why Do People Mix Cocaine And Caffeine?

Sometimes, cocaine and caffeine are mixed together before they have even reached the consumer.

The dealer usually does this in order to save money, and the customer is generally never informed.

Cocaine that has been laced with caffeine can create an intense high and is even more addictive than cocaine by itself.

People may also intentionally consume caffeine with cocaine by drinking coffee when using the drug.

What Happens When You Mix Cocaine And Caffeine?

While cocaine poses a lot of risks every time you use it, caffeine on its own is extremely commonplace and rarely poses any danger because people rarely consume enough caffeine to cause an overdose.

When the two are mixed, however, whether intentionally or unintentionally, caffeine can elevate the effects of cocaine to a dangerous level.

Not only will the high be more intense, but it may also come on faster. The result is that cocaine becomes more addictive in nature.

People using it may even struggle to use cocaine on its own going forward because they have become used to the stronger high that they feel when caffeine is added.

Cocaine And Caffeine Abuse Can Lead To Addiction

Caffeine is a widely used and socially acceptable substance. It even affects the same parts of the brain but in different ways.

Caffeine is a much more mild substance on its own, but when used in combination with cocaine, it actually makes cocaine more addictive.

Someone using both of these substances together is more likely to develop a polysubstance use disorder, which may require professional attention.
