You have never heard of this because it isn't socially acceptable to admit that you take drugs to work harder. The fact that you haven't heard of it doesn't necessarily mean it doesn't exist. What this comment says to me is that you aren't someone who would consider engaging in this sort of behavior and as such do not know people who engage in this sort of behavior. Depending on your length of time in the work force I bet you have worked alongside someone who has but they just never told you.
