The Anchorage Assembly's public safety and health policy committees held a joint meeting Friday to discuss how a proposed ordinance to allow on-site inhalation of marijuana could affect public safety. One concern: the effects of cannabis on drivers, and the potential for impairment. “What kind of training are they gonna be required to do to mitigate the risk of public safety, to identify the signs of impairment?” asked one officer from the Anchorage Police Department. Assembly member Chris Constant says training is being developed for employees to recognize when a patron shouldn't drive, similar to how bartenders are trained to identify someone too drunk to drive. But other Assembly members say that conflicts with another public safety concern.
