The statutes are difficult for a lot of people to understand so I will try to break it down. Marijuana is different from a DUI involving alcohol. Unlike alcohol, there is no "legal limit" when it comes to marijuana. Because marijuana is an illicit substance, having any amount in your system is considered illegal and subjects you to a DUI conviction. This means, the state does not have to prove you were impaired while driving, just that you had the illegal substance in you system while you were operating a motor vehicle. Clearly this is problematic since marijuana stays in your system long after the intoxicating effects have worn off. This means, if your daughter causes an accident and the police determine they should draw her blood and they find marijuana - she could face serious charges including aggravated assault (a felony). If your daughter is simply stopped and the officer believes she is under the influence of marijuana, they will draw her blood. If they find marijuana in her system, they can charge her with a Drug DUI. She would be subject to mandatory jail time (minimum of one day - max of 6 months), loss of license, about $1,500 in fines, increase in insurance rates, possible SR22 insurance requirement, and probation. Hope that information helps.

Great place to look is Chapter 4, Title 28 of the Arizona Revised Statutes. It's available online to the public at https://www.azleg.gov/arsDetail/?title=28
