Mixing cocaine with alcohol creates a dangerous compound known as cocaethylene, which significantly increases the risk of sudden death, according to a health expert.
Dr. Max Pemberton explained that while cocaine itself is harmful, its combination with alcohol triggers a unique reaction in the liver. Instead of metabolizing the substances separately, the liver fuses them into cocaethylene, a compound that is considerably more toxic than either parent drug.
Cocaethylene lingers in the body longer than cocaine, prolonging the strain on the heart. Research indicates that the presence of cocaethylene can elevate the risk of sudden death by 18 to 25 times compared to cocaine use alone. Cocaine is already known to put immense stress on the cardiovascular system, and cocaethylene intensifies this effect.
The expert noted that the danger is not confined to long-term drug users. Many ordinary young individuals who engage in heavy drinking and drug use during a single night have fallen victim to this combination.
The deceptive nature of cocaine in this scenario is that it masks the body's natural cues for stopping alcohol consumption. Users may feel they can continue drinking without experiencing the usual drowsiness or queasiness, leading them to consume alcohol to levels they would not reach otherwise, all while unaware of the toxic substance they are brewing.
Furthermore, the combination of cocaine and alcohol has been linked to increased aggression. This is particularly concerning in the context of public events like football matches, where domestic abuse incidents have been observed to rise. The heightened emotions, combined with alcohol and a stimulant that can shorten tempers, create a volatile situation.
Despite official surveys showing stable or even declining cocaine use among young people, death rates involving the drug have been climbing. In 2024, deaths involving cocaine reached 1,279, a 14% increase in a single year. This trend is attributed to changes in the street drug itself. Cocaine purity has more than doubled in the last decade, with average purity now routinely over 80%, compared to around a third in 2013. This means that a dose that once provided a mild effect can now deliver a significantly stronger and more unpredictable hit.
Dr. Pemberton emphasized that most cocaine-related deaths involve multiple substances, with alcohol frequently being a contributing factor. He recalled that many individuals who believed they had their drug use under control, often dismissing it as occasional weekend use or "just a bit of fun," were ultimately undone by it. Cocaine, he warned, has a potent ability to let people maintain this illusion until it is too late.
He advised individuals celebrating events like the World Cup to enjoy late nights and drinks responsibly, but to avoid stimulants that promise extended enjoyment at a far greater cost. The most severe outcomes of such nights, he cautioned, may not be related to the event itself but to the dangerous mixture of drugs and alcohol.
