Driving

The states set up marijuana analogies to drunk-driving laws, setting driver blood limits for pot's psychoactive chemical, THC. The laws are new, and it's too soon to say whether legal pot has made highways more dangerous in Colorado and Washington. Both states report seeing more positive driving-high tests, but it's not clear whether that's because of increased driver use or increased testing.
