PIERRE, S.D. (WNAX) – The battle against illegal drugs continues in South Dakota, but the sources are changing.

Attorney General Jason Ravnsborg says meth is still number one.

Ravnsborg says not much meth is being cooked up in local labs.

Ravnsborg says they are starting to see more fentanyl.

Ravnsborg says he will be working with legislative interim committees that will be studying illegal drug use.
