"He had eaten a [cannabis] edible and just couldn't handle it," MacIntosh said.
Cannabis overdoses are something he said he's personally witnessed at the bar three times in the past year.
That mirrors a trend happening across the country — as the Oct. 17 date for legalization of recreational pot looms, CBC News has learned that cannabis-related emergency room visits have spiked.
Data from the Canadian Institute for Health Information (CIHI) shows that over the past three years the number of emergency room visits because of cannabis overdoses in Ontario has almost tripled — from 449 in 2013-14, to nearly 1,500 in 2017-18.
In Alberta, the number has nearly doubled over the same timeframe, from 431 to 832.
Symptoms of cannabis overdose — or more precisely, THC poisoning, THC being the main psychoactive chemical in pot — include elevated heart rate and blood pressure, anxiety, vomiting and in some cases psychosis, possibly necessitating hospitalization.
