Sewer sam­ples show Haligo­ni­ans use more cannabis than other Cana­di­ans

StarMetro Halifax - - FRONT PAGE - TARYN GRANT

The re­sults of a pi­lot study that mea­sures how much cannabis has moved through hu­man bod­ies and been flushed down the toi­let add to the ev­i­dence that Haligo­ni­ans con­sume more cannabis than other Cana­di­ans.

Sta­tis­tics Canada is turn­ing to new meth­ods of mea­sur­ing cannabis con­sump­tion af­ter not­ing that peo­ple are likely to un­der-re­port pot use be­cause of stigma and a re­luc­tance to di­vulge black-mar­ket pur­chases. Test­ing for chem­i­cal com­po­nents of cannabis that have gone down the drain could help to paint a more accurate pic­ture, the or­ga­ni­za­tion says.

Us­ing a tech­nique called wastew­a­ter-based epi­demi­ol­ogy (WBE), Sta­tis­tics Canada says it has es­ti­mated the to­tal mass of cannabis con­sumed in Hal­i­fax, Mon­treal, Toronto, Ed­mon­ton, and Van­cou­ver from March to Au­gust 2018.

A re­port re­leased Thurs­day shows that Hal­i­fax sur­passed each of the four other cities in the av­er­age amount of cannabis con­sumed per per­son, per week, at about 1,300 mi­cro­grams.
