You know what else it means? It means it is a program that has to be put in place and kept up. It means that besides the costs of the drug test, you have the administrative costs of the people and infrastructure that track the program. It also means that people over the long haul get tested more than once. When you consider that most of the people will test negative, you have increased your cost with them for absolutely no reason at all. Now you are paying for both their unemployment, and their drug test, thus increasing cost and making the program more expensive. If you can't get that, maybe you ought to go back to second grade, and learn to add again.
Secondly, you can't random test people on unemployment. These people are not employees of companies, they are citizens. Citizens must all be treated equally under the law, which means if one person is tested, they all have to be tested.
Lastly, you make the assumption that people on drugs are not productive. That is not true. There are plenty of people who take drugs who have good jobs, and when they don't have a job, they look for work just like everybody else. Just because they do substances in their spare time does not make them any less responsible.
