For actual welfare recipients, it's probably a good idea, but I think that people collecting unemployment insurance should be not be required to participate in drug testing. Unemployment insurance is not the same thing as "welfare", as the recipients worked and got laid off usually through no fault of their own - and they paid into the system from their salaries, along with employers.

Plenty of Americans are now, and will soon be, getting their first taste of unemployment benefits. It would be totally unrealistic to test them all, even in Floriduh.
