A measure to require drug testing as a condition for receiving welfare has been signed by Tennessee Governor Bill Haslam.
The legislation - which passed the senate and the house - requires new welfare applicants to undergo a special screening process.
If suspicion is raised after the screening, then the applicant would be drug tested.
The proposal differs from an original version that would have required blanket testing.
Haslam told reporters Thursday that he's comfortable with the legislation because the Department of Human Services will develop the rules for the testing, and the State Attorney General must make sure the process is constitutional.
