Cocaine, though, is frequently consumed alongside alcohol, which produces a new substance in the body called cocaethylene.

然而，可卡因常常与酒精同服，会在体内形成新的物质：古柯乙烯。

Cocaethylene has similar actions to cocaine, but its half-life is longer, and it has an greater-than-additive effect, enhancing the body's responses to both alcohol and cocaine.

古柯乙烯与可卡因作用相似，但半衰期更长，且具有比（酒精和可卡因）累加效应更强的影响，能增强身体对酒精和可卡因两者的反应。
