"I believe that although Qin Xiang does have a few valid points, it is not necessarily true that every student has "access to caffeine" or any other drug. It is not true that every single person has access to these performance enhancing drugs. Sometimes these drugs are not available due to the lack of funds. Although something is available to the public, it is not something which every single person is able to obtain. For example, richer people may be able to obtain more drugs as well as a larger variety of drugs which may further enhance their cognitive ability, among other abilities, which in turn may also cost more. Thus I would like to point out that there is nothing which is absolutely available to everyone. If everyone has access to a drug which may be BOUGHT, then richer people would most obviously have access to more drugs than poorer people and thus it is not fair. In this case of caffeine, some students might be so poor that even water is a luxury, let alone coffee and tea. Thus, following QX's philosophy, caffeine here would be unethical."

"However, caffeine is probably as much a “drug” as chicken essence which, according to studies, also enhances cognitive ability [http://nutriweb.org.my/publications/mjn009_1/mj n9n1_art3.pdf]. Does that mean that chicken essence should be banned before activities such as examinations as well as competitions? In addition, as tuition also gives the student an unfair advantage over those who do not go for tuition, should tuition also be banned then? These are among the other objects and activities in daily life which gives people a so called unfair advantage over others. Many activities as well as food products affect one's ability to perform in various activities and it might be said that these give each person an unfair advantage. If caffeine should be banned then all these products and activities should also be banned. Even schools give unfair advantages, like some students going to IP rather than the Express streams which teach differently and thus the students in the IP receive an unfair advantage over that of the Express. Doesn't this constitute as being performance enhancing? Thus if caffeine is banned for its aiding in performance in various areas then shouldn’t these programmes be banned as well?"
