Final answer:
Cocaethylene is produced when cocaine and alcohol are consumed together, leading to greatly increased heart rate, elevated blood pressure, prolonged euphoria, and a higher risk of immediate death. It enhances the cardiotoxic and neurotoxic effects of cocaine.
Step-by-step explanation:
The formation of cocaethylene occurs when cocaine and alcohol are consumed together, and it can result in a mix of heightened symptoms compared to those produced by cocaine alone. When discussing the toxicity of cocaethylene, its effects can include: A. greatly increased heart rate and elevated blood pressure B. prolonged and enhanced euphoria relative to taking cocaine alone C. an increased risk of immediate death. D. all of the above. Cocaethylene has been found to increase the cardiotoxicity and neurotoxicity associated with cocaine use. Moreover, it can potentiate the risk of sudden cardiac events and liver damage. Users of cocaine and alcohol together need to be aware of the significant increase in harmful effects, including a rise in the likelihood of immediate and potentially fatal outcomes.
