In what would be a precedent-setting case, the state's high court was asked Friday to decide, in essence, whether someone who smokes marijuana -- even legally -- can ever drive in this state.

Republicans should get out front for once and lead the movement to legalize marijuana. It makes sense any way you look at it.

Use spice and drive, and it may be more likely you’ll pay for the crime in Mesa.

The organization that funded Arizona's 2010 medical marijuana initiative says lawmakers who now want voters to scrap the program are missing the point of a study on teen use.

PHOENIX -- Saying voters have seen enough, a veteran lawmaker wants to give them a chance to repeal the state's 2-year-old medical marijuana program.

Drug paraphernalia, weapons, a lack of clothing and an alligator.

Prosecutors and police throughout the Valley are continuing to push back against the war on synthetic drugs.

Nicotine is a very addictive substance that is very deadly, yet we have almost no crime associated with it. Why? It’s legal.
