The state of Tennessee has joined 10 other states in drug-screening welfare applicants.

People who refuse to participate are disqualified, according to The Tennessean.

Since the law went into effect July 1, more than 800 drug screenings have been completed.

Out of those screened, four refused to participate in any type of drug screening and just one person failed a drug test.

Those who test positive for drugs are referred to a treatment facility. They are still eligible for benefits as they complete their treatment and test negative for substances at a later date.

The Department of Human Services pays for the drug tests at $20-$35 a test.
