The standard for which Marijuana Impairment presumptive levels in DUI prosecutions are likely to be under scrutiny due to what some are regarding as unproven scientific evidence. Presumptive impairment levels for THC concentration in blood samples might not satisfy legal requirements from an actual driving impairment perspective. They could in-fact be regarded arbitrary and not scientifically supported.
States do have the legal authority to establish presumptive impairment levels, that is a measurable quantity of a substance sufficient to establish an element of DUI. In fact while the present presumptive alcohol level in the United States for ordinary drivers is .08, states have established .04 for commercial vehicle driving and some states have .02 for those under twenty one years of age who violate analog status offenses that do not define impairment as an element.
Now, the American Automobile Association’s Foundation for Traffic Safety cited a study that differences between individuals can be wide and greatly varied regarding impairment at a set blood THC level. While some drivers show obvious signs of impairment at low levels of THC blood concentration, other persons can have greatly elevated readings and show no outward appearance of signs of DUI.
The academic world lost a gifted member in the murder of UCLA professor William Klug, who was gunned down by a former student Mainak Sarkar, 38. Sarkar is a former doctoral student that Klug mentored and was upset about his grades, according to police. Sarkar left what is described as a “kill list” that led police to the body of a Minnesota woman who was gunned down in her home. The list included another professor’s name, but thankfully that professor was not hurt.




We recently discussed the tragedy in Chile where a man sought to commit suicide by jumping into a lion enclosure at the zoo — resulting in two lions being shot and killed to protect him. Now in Cincinnati, a parent failed to properly supervise her 4-year-old son who fell into gorilla enclosure. Even though the lowland gorilla did not seem to be trying to hurt the child, he was nevertheless killed to guarantee the safety of the child.
