WICHITA, Kan. (AP) — Responses from nearly 400 Kansas law enforcement agencies and prosecutors to a survey by the state’s attorney general suggest legal Colorado marijuana is having a big impact on Kansas — and not all of it negative.

The Wichita Eagle reports that the responses indicate less marijuana is flowing into the state, but what is coming in is more potent than pot smuggled in from Mexico.

The survey also shows the legal system has been affected by changing attitudes toward marijuana, with some jurisdictions no longer enforcing pot laws.

Kansas Attorney General Derek Schmidt says he’s concerned about the growing popularly of edibles, which are foods made with marijuana or marijuana oil.

Colorado is one of four states that have legalized marijuana. Five others will vote on legalization this fall.
