Vancouver uses the smallest cannabis in Canada, by sewage


Canada Statistics have released a report that measures the use of cannabis in the main cities of Canada based on sewage analysis.

The report collected data from five major cities, including Vancouver, Edmonton, Toronto, Montreal and Halifax. In particular, the report is studying the "Vancouver Metro-area," Montreal Island, Edmonton City, Toronto City, and Halifax Central.

Vancouver finally died when it came to the size of cannabis that used the head, which could be a shock to some. Perhaps, even more surprising, however, that Halifax was the leader in the use of cannabis per head.

With this in mind, a number of factors push on the overall results. For example, the report states that "the wastewater treatment works in Halifax have located in the city's core area and as a result, the use of cannabis may not have been measured representing the city's entire city population. "

In addition, the temperature, acidity and presence of industrial chemicals or bacteria in the city's sewer system could also change the results.

So, how exactly are cannabis levels measured in wastewater?

Researchers used a new form of research of the name "waste water epidemiology" in order to measure the metabolites that people eliminate from their bodies.

"When people use cannabis or tetrahydrocannabinol (THC), the main seico-active cannabis container, their bodies process the cannabis into metabolites (THC-COOH, in the case of THC) be deleted later of the body and usually squeezed into the municipal wastewater system, "reads the report.

"By direct analysis of THC-COOH concentrations in wastewater, Canadian Statistics can estimate the total amount of cannabis used."

The pilot project covered areas that included 15 wastewater treatment plants in five large urban centers throughout Canada, which represent almost 8.4 million people. As a result, the project has done one of the ongoing pilot tests, WBE, to date.
