The world's view of marijuana, or pot, is changing. We see this with an ever-growing amount of states passing medical marijuana laws, and have also seen it with the 40% of California residents that voted to legalize pot outright in California. Despite these facts, Arizona's laws on the subject haven't changed. Arizona has incredibly strict DUI Drugs laws on its books, under which guilt is determined by the mere presence of a drug or its metabolite in your system. That means that if you smoked one marijuana cigarette or joint three or four weeks ago, then every time you drove during that time (until your urine was absolutely free of the marijuana metabolites), you were driving under the influence of drugs (also known as DUI Drugs).
