That half page of text is literally the whole article, quoting a single police referencing traffic stops like they imply legalized weed is causing more dangerous driving and traffic stops where they can't seize property anymore without linking the possession of medicine to an effect on their driving. There's no study that shows a link between legalizing cannabis and increased vehicle accidents or fatalities. The article reads like it was written as cop public relations with an alcohol trade group lobbyist looking over their shoulder.

They ignore the position that drug abuse is a medical issue not a legal issue, and all drugs should be legalized for both the safety of the users and the community because it reduces violent crime and dangerous, unregulated black markets.
