Ever since Colorado has loosened the grip on marijuana and made it legal to have small amounts, there has been an uptick of marijuana in Kansas. There is no hard evidence of this so Kansas law makers are deriving a plan on how to track this.Kansas Attorney General Derek Schmidt has launched a statewide project to collect information about how marijuana acquired in Colorado is entering and affecting Kansas.Since Colorado’s widely publicized decision more than three years ago to “legalize” acquisition and possession of small amounts of marijuana under its state law, Kansas law enforcement agencies have consistently reported encounters in Kansas involving marijuana acquired in Colorado. Existing criminal justice information systems are inadequate to track the phenomenon because they do not collect information about the origin of marijuana encountered by Kansas law enforcement, and they cannot readily be modified to do so.
