The case for testing employees, students and those applying for government benefits for drug use seems obvious.
Drug testing can deter people from using illegal drugs.
It can catch people who are breaking the law. Tens of millions of Americans now urinate into jars or pluck a few hairs so their employers or school authorities can determine whether they have consumed a detectable drug in the past few days or weeks. Many now do it without thinking twice. In some respects, drug testing is rapidly becoming as much a national tradition as Mom and apple pie. Some are retired drug warriors pursuing their old campaigns with new and more profitable tactics.
