Halifax Wastewater Reveals High Cannabis Use

A study shows Halifax's cannabis metabolite levels in wastewater are nearly double those of other major Canadian cities.

Statistics Canada's 2023 survey found 748 milligrams of THC metabolites per 1,000 people per day in Halifax.
The average THC metabolite level among other surveyed cities, including Toronto and Montreal, was 448 milligrams.
Researcher Lisa Oliver highlighted the unbiased nature of wastewater analysis for measuring drug consumption.
Dr. Phil Tibbo suggested cultural acceptance and a large student population may contribute to Halifax's high cannabis use.
Nova Scotia may consider policy changes, such as limiting THC potency or adjusting the legal purchase age.
