One thing I don't like is that you seem to repeatedly be asking if people felt "pressured" to take drugs to catch up with their colleagues or what their "fear" is. If you want to know why, you should ask "why", and not push your own narrative with leading questions. I think a lot of people, including myself, would actually tell you that they take performance enhancing drugs simply to make themselves the best version of themselves, not to compete with others. The fact that these people are highly competitive is simply because they are over-achievers.
Thanks for clarifying. I don't have conclusions yet, but I do have ideas and didn't think my questions were leading. So apologize if they seem so. If you don't feel "pressured"--overtly or subvertly--to take a substance but just do it because you think it would be fun, then that's the answer, right? And I'll learn from that.
