I work in the financial sector – very high pressure environment – and all of my colleagues do coke during work hours. I somehow got into it and now I’m scared to say that I don’t want to do it any more. I know they’d turn on me as it happened to another guy before and they made him leave the company. What can I do to maintain my health, job and dignity? G. from Frankfurt am Main

First of all let me tell you that you are living the glamorous life that we all dream of, so don’t feel so sad. You have a great job, your health is fine (we all die eventually) and what exactly is dignity?? My one concern is that you’re doing coke only during the work hours. That is the real problem!
