Any attempt to address the public health problem of drug abuse through the criminal law is inappropriate, ineffective, and leads to widespread violations of privacy and other civil liberties. Criminalizing the use, possession, manufacturing and distribution of drugs violates the principle that the criminal law may not be used to protect individuals from the consequences of their own autonomous choices or to impose upon those individuals a majority conception of morality and responsibility. If a drug user performs an action that does harm in any way legitimately cognizable by the state, that conduct may be criminalized directly. As far as protecting players from themselves, this is not a valid argument for drug testing. Drug use is a private matter.
College students are old enough to make informed decisions about their lives.
If they chose to use drugs, that is their decision. Bottom line, get off their backs and let them decide if drugs are the right or wrong thing to do. A level playing field is a great excuse to test for drugs. It sounds good, but it is still an invasion of privacy and a baby sitting technique to keep an eye on students private lives. The playing field has never been level.
