Cocaine is on the rise in New Zealand. We’ve been hearing more people saying they’ve had an unpleasant time - especially when using cocaine while they’re drinking alcohol 

When you take coke and drink alcohol together, they combine to make a drug called cocaethylene. These are the only two drugs known to make a new drug inside your body. 

Mixing any drugs together can be risky, but this combo is particularly common and it pays to know what to watch out for.  

What is cocaethylene 

Cocaethylene is a substance made when your liver breaks down alcohol and cocaine together. While the effects are similar to cocaine, cocaethylene lasts longer and can put more strain on your body, particularly your heart.  

How does cocaethylene affect you?  

  • Cocaethylene stays in your body almost twice as long as cocaine does. This means that if you take more cocaine after your first dose, you can end up with a large amount in your system. This seriously increases your risk of overdose.

  • Cocaethylene can put extra strain on your heart. Compared to cocaine alone, cocaethylene is more likely to cause damage to your heart, including heart attack. Regularly using cocaine and alcohol together can cause long term damage to your heart.  

  • You might experience more unpleasant effects. Cocaethylene has stronger effects than just cocaine alone, including the unpleasant aspects. You may be more likely to experience anxiety, agitation, jitters, nausea, dizziness and a racing heart. It also increases your risk of experiencing more serious side effects such as seizures, psychological distress and overheating.  

  • Cocaethylene is toxic to your liver. Research shows that cocaethylene is a liver toxin. Mixing cocaine and alcohol regularly or in very high doses carries the risk of liver damage. If you have a liver condition such as hepatitis or cirrhosis, we’d recommend avoiding the combo of cocaine and alcohol. You may not realize how intoxicated you are.

    Alcohol is a depressant drug which slows down your body and brain, and cocaine is a stimulant which speeds up your body and brain. They can ‘mask’ the effects of each other, even though they’re both still in your system. You may not realize how intoxicated you are and end up taking more. This can lead to overdoses and to worse comedowns or hangovers the following daybummer

How can I be safer with cocaine and alcohol? 

Ideally, it's safest not to combine alcohol and cocaine to reduce the risks from cocaethylene. However, if you are planning on drinking and using cocaine, here are a few things we recommend:

  • Space out your doses as much as possible.  To avoid cocaethylene forming in your body, you need to leave as much time as possible between drinking alcohol and using cocaine (or vice versa). A standard drink takes at least an hour to be processed by your body. So, if you have had 4 drinks, wait at least four hours before using cocaine. Be aware that these drugs will still be in your body, even after you no longer feel their effects - so you may need to wait longer than you think. 

  • Avoid taking more cocaine. Cocaethylene stays in your body more than twice as long as cocaine alone does. This means that if you redose (take more after your first dose) frequently, these doses will ‘stack up’ in your body and increase your risk of overdose and other harmful effects.  

  • Stick to lower doses. To reduce your risk of feeling unpleasant or harmful effects from cocaethylene, consider taking a lower dose of cocaine and drinking less alcohol, or swapping for lower alcohol drinks (such as light beer or low-alcohol wine).  

  • Avoid mixing with other drugs or medicines. Because cocaethylene stays in your body much longer than cocaine alone, it is extra important to avoid mixing with other drugs and medicines. This can increase the strain on your body 

What should I do if someone is experiencing an overdose from cocaethylene? 

If you or someone around you is mixing cocaine and alcohol, it’s important to know the signs of overdose 

Cocoethylene can cause your body’s functions to speed up dangerously - this is sometimes called ‘overamping’. Signs of overamping include:  

  • A very high temperature (may be sweating)

  • Difficulty breathing

  • Extreme agitation or paranoia

  • Chest pains

  • Seizures

  • Loss of consciousness 

If the person is experiencing any of these symptoms, call 111. Stay with the person and reassure them. If they are breathing and it is safe to do so, place them in the stable side position (recovery position). Help them cool off if they’re very hot
