在一个著名的实验中，美国心理学家汉斯·布雷特对可卡因成瘾者进行了核磁共振成像。

He was a man of extraordinary energy and productivity, in part because he was a very serious cocaine addict, but also just in general.

他是一个精力充沛、生产力非凡的人，部分原因是他是一个非常严重的可卡因瘾君子，但也只是一般而言。

Then I realised that Holmes is a cocaine addict and Freud had been an early proponent of cocaine, starting as a use for anaesthetic during eye surgery, but he also was a user.

然后我意识到福尔摩斯有可卡因毒瘾，弗洛伊德早期拥护可卡因，将它作为眼部手术的麻醉剂，但是他也吸食。
