"Bad" is subjective. I drink caffeine to stay awake or to wake up; getting my work done is not "bad" for me. I drink alcohol and smoke cigarettes because smoking is relaxing and helps me concentrate and drinking... I won't get into that here. I exercise because it makes me feel good. I eat healthy because I think non-junk food just tastes better. In my mind, all of these things are not "bad" for me. Some may be bad for my physical health, but if physical health were humans' only consideration we would all live in plastic bubbles and eat synthesized protein mash or something. If somebody wants to take Provigil for 30 years and it effectively doubles their productivity and concentration while at the end of which turning their mind to mush, who are we to judge?
