Arizona Ruling Refines Definition of Marijuana DUIs

Lakeland, FL (Law Firm Newswire) August 20, 2014 – DUIs usually refer to driving while under the influence of alcohol. With marijuara being more commonly used for a variety of reasons, such as medically/recreationally, comes the debut of marijuana DUIs.

“As marijuana is sometimes used for medical purposes, there is a huge gap among states as to what defines driving under the influence. Twenty-three states and The District of Columbia are currently struggling to find an answer to that question. Interestingly, an Arizona court may have provided the solution to the question –and not just for Arizona, but across the country, should law enforcement and politicians find it flexible enough to adapt to their needs,” observed Thomas C. Grajek, a Lakeland, Florida criminal defense lawyer.

The main issue is one of impairment. So, how long does cannabis stay in the body? The most familiar active compound is tetrahydrocannabinol (THC). THC combines with at least 483 other compounds in the marijuana plant, including cannabidiol, cannabinol, tetrahydrocannabivarin and cannabigerol. When an individual smokes marijuana, two compounds come into play that could impair an individual. The first compound causes the well-known “high,” and the second is an inactive compound that stays in the system after the high.

This inactive compound can be detected via blood and/or urine tests.

Eight states have zero tolerance for marijuana found in the blood stream of an accused, including inactive compounds. Other states demand indication of impairment before charges are laid. And still other states have limits in place for how many active marijuana compounds may be in a person’s system.

In a recent Arizona case, the Arizona High Court ruled that officers cannot charge drivers for being under the influence of marijuana unless the driver is impaired when stopped by police. Drivers in Arizona are no longer at risk of being charged for DUI if they have an inactive metabolite in their blood stream. In part, the Court’s decision said: “Drivers cannot be convicted of the . . . offense based merely on the presence of a non-impairing metabolite that may reflect the prior usage of marijuana.” The inactive metabolite, carboxy-THC, may be found in the blood stream for up to several weeks after smoking the drug.

The dispute was a major issue in Arizona, as the state’s 48,000 registered users were technically breaking DUI laws by driving. “Drivers may still be prosecuted if the active compound THC or the metabolite Hydroxy-THC are present, as both create inebriating effects,” outlined Grajek.

As always, there are exceptions to all rulings in all states.

“Know what rules are in place in your state of residence,” said Grajek, “and if you are uncertain how they may apply to you as a registered medical marijuana user, make sure to speak to a knowledgeable criminal defense attorney if you are charged.”

  • Arrest made in Polk County "SWAT"ting incident involving "anonymous" calls to police to lure SWAT team to high school.
    A Canadian juvenile was arrested in the recent Polk County “swatting” case.  “SWATting” is when an individual attempts to lure the SWAT time to respond to a location for a fake threat of some type. Polk County deputies allege the teen anonymously placed hoax calls to law enforcement officials in an effort to lure SWAT teams to respond to Ft. Meade high school over the past four-months.  Deputies say the investigation began in September, when an unidentified male called the sheriff’s office and Fort Meade High School and said he was going to “drive to Fort Meade High School in […]
  • Just in time for Christmas, Polk Sheriff Grady Judd's prostitution sting results in 61 arrests.
    Sheriff Grady Judd will hold a press conference today to announce the results of the latest Polk Prostitution sting from last week.  The sting was part of a  undercover operation targeting individuals who respond to online advertisements on Backpage.com.  The online ads are usually listings for escort or massage services, but once the person responds to the hotel, the undercover deputies try to make an arrest for an illegal activity.  These undercover officers can be very aggressive and often do most of the talking.  The sheriff was also targeting human trafficking which is a much more serious felony offense. There are some harsh […]
  • Medical marijuana amendment fails in Florida, pot still illegal to possess. What defenses do you have to a possession of cannabis case?
    Florida’s medical marijuana amendment did not pass yesterday in the election.  Even though a majority of the voters voted in favor of passing the medical marijuana amendment, receiving 58% of the vote, it fell 2% shy needed to pass.  In 2006, Florida voters decided all constitutional amendments needed a “super majority” to pass (60% instead of 50%). Ironically, that amendment that now requires a super majority, only passed with 57.8% of the vote.  Whether or not the issue is placed back on the ballot is unknown at this time.  John Morgan of Morgan & Morgan who spearheaded the campaign had previously […]
