The charges are dismissed against a Janesville man accused of using his teenage daughter to deliver synthetic marijuana.
Quentin Allen Ellefson was charged in December of 2013 with using a child to distribute of deliver drugs following an incident involving his 13-year-old daughter.
The Rock County Attorney's Office says following Ellefson's arrest, the suspected synthetic marijuana was sent to the state crime lab, where it was determined that the specific compound used is not listed under Wisconsin's controlled substances act.
The criminal complaint indicates a Janesville mother broke the case when she found her son sick in bed after buying synthetic marijuana.
The complaint says she used her son's cell phone to text message the girl to buy more of the synthetic drug, and then waited for police to arrive.
The girl later told police Ellefson obtained the drug from a smoke shop in Elkhorn.
The County Attorney's Office says manufacturers of synthetic marijuana rapidly introduce new chemical compositions to circumvent the Controlled Substances Act.
