An Overview Of Alcohol Testing And Interpretation In The 21st Century, Anna Kelly, Ashraf Mozayani
Ashraf Mozayani, Ph.D., PharmD
Ethanol analysis is the most commonly carried out drug testing in a forensic toxicology laboratory. Determination of blood alcohol concentration (BAC) is needed in a multitude of situations, including in postmortem analysis, driving under the influence (DUI) and drug-facilitated sexual assault (DFSA) cases, workplace drug monitoring, and probation investigations. These analyses are carried out by direct measurement of ethanol concentrations as well as of metabolic by-products, such as ethyl glucuronide (EtG) and ethyl sulfate (EtS). This review article will discuss pharmacokinetics, including absorption, distribution, and elimination of ethanol, methods for the detection of ethanol, the effect of ethanol on human …

Liquid chromatography time-of-flight mass spectrometry (LC-TOF-MS) analysis provides an expansive technique for identifying many known and unknown analytes. This study developed a screening method that utilizes automated solid-phase extraction to purify a wide array of analytes involving stimulants, benzodiazepines, opiates, muscle relaxants, hypnotics, antihistamines, antidepressants and newer synthetic "Spice/K2" cannabinoids and cathinone "bath salt" designer drugs. The extract was applied to LC-TOF-MS analysis, implementing a 13 min chromatography gradient with mobile phases of ammonium formate and methanol using positive mode electrospray. Several common drugs and metabolites can share the same mass and chemical formula among unrelated compounds, but they are …

With Reckless Abandon: Haneef And Ul-Haque In Australia's 'War On Terror', Mark Rix
Mark Rix
This brief paper considers the political and social implications of the manner in which Australia has prosecuted the so-called ‘war on terror’. It does this by investigating relevant aspects of Australia’s anti-terrorism legislation and the performance of Australian security and law enforcement agencies, namely, the Australian Security and Intelligence Organisation (ASIO) and the Australian Federal Police (AFP). Focusing on the Haneef and Ul-Haque cases, the paper will consider how the political climate created by the former Federal Government’s legislative approach to the war on terror has influenced the performance of these organisations. By focusing on these two cases, the paper …
