TOPEKA, Kan. (AP) — Kansas Attorney General Derek Schmidt is gathering data from local law enforcement agencies in an effort to measure the impact of Colorado-purchased marijuana on the state.

The Lawrence Journal-World reports that Schmidt has sent more than 500 survey forms requesting information to county and district attorneys, as well as police departments. He said he would make the survey results public when they are compiled later this year.

According to Schmidt, there are numerous accounts of marijuana being illegally brought into the state from Colorado. He says his goal is to get a clear picture of what’s happening in the state so “policymakers can make informed decisions.”

Kansas law still prohibits the possession or distribution of marijuana.
