“Our mission is to improve the lives of millions, worldwide. Working with great partners like Gaize helps make this mission a success, by providing the clinical evidence needed to bring Impairment Detection Devices like this to market, and make our roads safer.” – Peter Wojewnik, Partner, dicentra

dicentra, a world-renowned Contract Research Organization (CRO) and global consulting firm, is pleased to announce that it has opened participant enrollment for a new groundbreaking cannabis impairment study with its client, Gaize. The study is seeking 350 participants to volunteer at dicentra’s clinical research site in Toronto, Canada.

Cannabis use can negatively impact a driver’s ability to safely operate a motor vehicle by affecting motor skills, slowing reaction time, and impairing short-term memory and concentration. Despite this, according to research done at Western University, drug-impaired driving increased by 43% in the first full year after Canada’s federal legalization of cannabis. This statistic is further compounded by findings from 2021’s Canadian Cannabis Survey that one in four cannabis users admit to having operated a vehicle while under the influence of cannabis.

Approved alcohol screening devices (ASDs) have been available to law enforcement agencies for over four decades. These devices provide an easy means of ascertaining both the presence and the concentration of alcohol at a roadside traffic stop. Unlike alcohol, there are currently no comparable screening devices to ascertain the level of cannabis impairment. In fact, studies suggest that the Standardized Field Sobriety Test (SFST), and roadside oral fluid screening may be unreliable measures of cannabis impairment.

The Gaize Cannabis Impairment Detection Device administers an automated standardized field sobriety eye test and captures high-definition eye movement video. The eye movement data is used to determine cannabis intoxication and the captured footage is securely stored and can later be used as evidence to demonstrate the signs and symptoms of impairment. This product simultaneously tackles the issue of safety, accuracy, and fair and reliable evidence in potential prosecution and defense cases.

“The implications of this study on road safety are immense. That’s what makes studies like this one so important,” says Peter Wojewnik, Partner, at dicentra. “Part of our mission is to improve the lives of millions, worldwide. Working with great partners like Gaize helps make this mission a success, by providing the clinical evidence necessary to bring Cannabis Impairment Detection Devices like this to market, and help make our roads safer.”

“The Gaize Cannabis Impairment Detection Device was designed specifically to provide a safe and reliable investigative device for cannabis detection,” says Ken Fichtler, CEO at Gaize. “Our proprietary cannabis detection software is the first of its kind to be used in a VR headset. This study will help us to determine how safe, effective, and reliable our device is.”

dicentra’s Toronto site will allow for fast recruitment of participants due to its downtown location being located on multiple transit routes, providing access to millions of potential participants within a 20-mile radius. dicentra prides itself on having the capacity to recruit participants quickly to meet the needs of clinical trial sponsors, offering a state-of-the-art clinical research clinic strategically located in the heart of Toronto, Canada.
