The Laurel County Detention center no longer allow letters to be sent in envelopes to inmates.
The jail changed its mail policy earlier this month, saying if someone wants to send a letter to an inmate they have to write it on a post card.
According to deputies, the policy was put in place to reduce the risk of illegal drugs being sent to inmates. Deputies said substances like Suboxone, an addictive drug that comes in strips, can be placed along the glue where envelopes are sealed.
Jamie Mosley, a Laurel County jailer, says this new policy should reduce drug abuse at the detention center.
"Really, the number one concern is the health of the inmates," Mosley said.
Legal mail is not included in the new policy. Inmates can still receive letters from government agencies as well as lawyers.
