People Against Drink Driving

A driver eats a cannabis gummy, waits a while, gets behind the wheel and returns a low THC reading. Surely that settles it? A new randomised trial says it does not. Cannabis edibles and driving do not follow the tidy rule that a small number in the blood means a clear head.That rule matters because

The oral fluid THC test can flag recent THC use in a driver with high accuracy. But it cannot say how much THC sits in the blood. That is the verdict of a Columbia University study published in Injury Epidemiology in 2018. Meanwhile, Australia’s food regulator has explained in a letter what the law covers

The Road Danger Nobody Is Talking About For decades, the conversation around drink driving has dominated road safety campaigns. But a quieter, equally deadly threat has taken root in the background, one that nobody can afford to ignore any longer. Drug impaired driving now claims hundreds of lives each year across the United States, and

Scientists at Virginia Commonwealth University (VCU) have built a prototype cannabis breathalyzer that could change how police detect drug use at the roadside. Forensic science professor Emanuele Alves led the federally funded project. The device is compact, inexpensive, and requires no laboratory support to deliver a result. The timing matters. Today, 25 US states and

The government has announced plans to slash the drink-drive limit in England and Wales to its lowest level ever. Furthermore, transport officials are warning drivers who plan to get behind the wheel should avoid alcohol entirely. Transport minister Lilian Greenwood delivered the stark message following the announcement of Britain’s first comprehensive road safety strategy in

A study examining the experiences of 100 Victorian drug drivers has uncovered significant confusion about road safety laws and exposed critical weaknesses in current approaches to tackling drug driving in Victoria. The research, conducted by Turning Point at Monash University and commissioned by the Transport Accident Commission, reveals that many drivers fundamentally misunderstand Victoria’s legislation

The Turning Point report reveals something crucial about drug driving behaviour: people describe it not as aberrant, but as embedded in everyday routines (work, socialising, stress management). This apparent ordinariness, however, must be understood within a broader policy environment where harm reduction has been promoted in relative isolation from robust prevention and supply reduction. The

Devastating new research from the American College of Surgeons has exposed the lethal consequences of cannabis-impaired driving, revealing that more than 40% of drivers killed in car crashes between 2019 and 2024 in Ohio tested positive for high levels of THC. Moreover, the findings, released last week, shatter the persistent myth that cannabis is a

A comprehensive decade-long study examining drug and alcohol presence in Victorian road crashes has revealed alarming trends, with methylamphetamine emerging as the most prevalent illicit substance detected in both injured and fatally injured drivers between 2010 and 2019. The research, published in Injury Prevention and led by Monash University, represents the largest investigation of its kind conducted

Abstract: Background Driving under the influence of alcohol and other drugs contributes significantly to road traffic crashes worldwide. This study explored trends of alcohol, methylamphetamine (MA), 3,4-methylenedioxy-N-methylamphetamine (MDMA) and Δ9-tetrahydrocannabinol (THC), in road crashes from 2010 to 2019 in Victoria, Australia. Methods We conducted a cross-sectional analysis using data from the Victorian Institute of Forensic Medicine and
