This is only a minute fraction of the drugs that make it into the country every day. When Tinker started their random drug testing program some years ago I made the statement that I knew of no one in my organization who would be a drug user. A drinker perhaps, but not drugs. People I never dreamed would use anything stronger than Coors Light were failing their drug tests.
Most people have no problem with it.
This is what the majority of the people want. Good kids should not have to be around drugs or those who use them while in our schools or any where else.
