Now that 33 states and the District of Columbia have passed legislation permitting the use of cannabis for medical reasons, construction managers have a new challenge as they work to keep projects on schedule while maintaining safe workplaces. When including the 10 states that have approved the recreational use of cannabis, it will likely become increasingly difficult to identify trade workers who are able to pass a pre-hire or post-accident drug screening.

In the case of alcohol, a breath test will provide information on whether a worker is likely impaired, and these standards have been in place for many years.
