Impairment is a significant workplace risk.

All businesses need to ensure they have a fit for purpose approach to managing impairment risks at work – impairment from cannabis, as well as other drugs and fatigue. 

New guide: 20 February 2025

The NZ Drug Foundation has today released a new guide: Medicinal cannabis: A guide for employers and employees to help employers and their workers better understand and manage medicinal cannabis and workplace safety concerns.

The Foundation worked with Construction Health and Safety New Zealand (CHASNZ), Dentons and Māori and Pasifika Trades Training to develop the guide. 

The cannabis legalisation referendum was a reminder of the need to manage the ongoing risk of impairment caused by drugs and alcohol.

In 2020 the Forum ran a two-part webinar series with the Candian Centre for Substance Use and Addiction, focusing on the Canadian experience of legalising cannabis. These webinar recordings are below and may be a useful resource for your organisation. 

Also included in the resources below is the  Cannabis Reflective Guide (2020) focusing on what organisations should consider when assessing the sufficiency of their approach to managing the risk of impairment at work.

“Cannabis is an impairment risk – regardless of its legal status.”
