Federal Study: THC-Positive Drivers Not More Likely To Be Involved In Motor Vehicle Crashes

Drivers who test positive for the presence of THC in blood are no more likely to be involved in motor vehicle crashes than are drug-free drivers, according to a federally sponsored case-control study involving some 9,000 participants. The study, published Friday by the United States National Highway Traffic Administration (NHTSA), is the first large-scale case-control study ever conducted in the United States to assess the crash risk associated with both drugs and alcohol use by drivers.

Arizona: Supreme Court Rejects DUI Per Se Standard For THC Metabolites

The Arizona Supreme Court this week rejected a 1990 state law that classified the presence of inert THC metabolites in blood or urine as a per se traffic safety violation. The Court concluded: “Because the legislature intended to prevent impaired driving, we hold that the ‘metabolite’ reference in § 28-1381(A)(3) is limited to any of a proscribed substance’s metabolites that are capable of causing impairment. Accordingly, … drivers cannot be convicted of the (A)(3) offense based merely on the presence of a non-impairing metabolite that may reflect the prior usage of marijuana.”

Oregon: Lawmakers Give Final Approval to Measures to Reduce Marijuana Possession Penalties

Members of the Oregon House and Senate have given final approval to two separate legislative measures, Senate Bill 40 and Senate Bill 82, to reduce penalties related to certain marijuana possession offenses. Both bills now await action from Democrat Gov. John Kitzhaber. If signed into law, the changes will take effect immediately upon passage.

Oklahoma Becomes Third State This Year To Approve Unscientific Per Se Limits For Cannabis

Oklahoma Gov. Mary Fallin has signed legislation, House Bill 1441, into law that criminalizes drivers from operating a motor vehicle if they have any detectable amount of THC and/or its inactive metabolites in their blood or urine. Under such internal possession statutes, known as zero tolerance per se laws, motorists who test positive for the presence of such compounds are guilty per se (in fact) of a criminal traffic safety violation, regardless of whether or not there exist supporting evidence that a defendant was behaviorally impaired by such compounds.

Study: Per Se Drugged Driving Laws Have Little Or No Impact On Traffic Deaths

The imposition of so-called per se drugged driving laws, which create new traffic safety violations for drivers who operate a vehicle with the presence of trace amounts of certain controlled substances and/or their inert metabolites (byproducts) in their blood or urine, do not reduce incidences of traffic safety deaths. That’s the conclusion of a just-published study by economists at the University of Colorado, Denver and Montana State University. The study is available from the Institute for the Study of Labor (IZA) in Germany as a Discussion Paper. Since 1990, 11 […]

Alternet: “Five Scientific Conclusions About Cannabis That The Mainstream Media Doesn’t Want You To Know”

Writing in the journal Science some four decades ago, New York State University sociologist Erich Goode documented the mainstream media’s complicity in maintaining cannabis prohibition. He observed: “[T]ests and experiments purporting to demonstrate the ravages of marijuana consumption receive enormous attention from the media, and their findings become accepted as fact by the public. But when careful refutations of such research are published, or when later findings contradict the original pathological findings, they tend to be ignored or dismissed.” A review of today’s mainstream media landscape indicates that little has […]
