Acute methamphetamine and alcohol usage alters gaze behaviour during driving: A randomised, double-blind, placebo-controlled study.

Background: Methamphetamine is frequently co-consumed with alcohol, yet combined effects on visually guided behaviours have not been experimentally assessed. This study examined whether methamphetamine and alcohol-induced changes in gaze behaviour can be accurately detected and indexed during a simulated driving task to establish characteristic patterns relevant to traffic safety.

Methods: In a randomised, placebo-controlled, cross-over study design, the effects of acute oral methamphetamine (0.

Acute neurocognitive and subjective effects of oral methamphetamine with low doses of alcohol: A randomised controlled trial.

Background: Methamphetamine is often recreationally co-consumed with alcohol due to desirable off-target effects; however, the acute neurocognitive and subjective consequences of combined use are unclear.

Methods: In a randomised, placebo-controlled, counterbalanced, cross-over study design, the effects of acute oral methamphetamine (0.42 mg/kg) were assessed with and without low doses of alcohol (target 0.

Supported liquid extraction (SLE) for the analysis of methylamphetamine, methylenedioxymethylamphetamine and delta-9-tetrahydrocannabinol in oral fluid and blood of drivers.

Since 2006, the South Australian Government has been conducting roadside oral fluid testing of drivers for the illicit drugs methylamphetamine (MA), methylenedioxymethylamphetamine (MDMA) and Δ(9)-tetrahydrocannabinol (THC) using the Securetec Drugwipe II Twin and Alere DDS 805 AP saliva collection kit. Forensic Science South Australia carries out the confirmatory analysis by LC/MS for the positive test results of oral fluid roadside testing along with the pre-screened ELISA positive road traffic accident blood samples. The number of blood and oral fluid samples received in the laboratory has been steadily increasing during this time, and over 10,000 samples were received in 2014.
