In total, the areas surveyed represent nearly 8.4 million Canadians.<\/p>\n<p>StatCan noted there were often large disparities in the amount of cannabis detected month-to-month, and stressed that its results are considered \u201cpreliminary and experimental.<\/p>\n<p>\u201cStatistics Canada is still exploring the benefits and limits of using WBE to produce statistics on drug use,\u201d a recent report posted on StatCan&#8217;s website reads.<\/p>\n<p>\u201cSubsequent tests and results will allow the agency to better assess the long-term feasibility of using wastewater as an official data source.\u201d<\/p>\n<p>The study was launched amid concerns that Canadians may be under-reporting their cannabis use due to stigma around the drug a reluctance to disclose purchases from \u201cnon-regulated suppliers.\u201d<\/p>\n<p>\u201cOne consequence of under-reporting is that the size of the black market for cannabis will be similarly underestimated,\u201d the report, published last Thursday, states.<\/p>\n<p>\u201cAs a result, without a direct measurement of cannabis consumption, the reduction of the black market for cannabis, one of the objectives of the legalization of non-medical cannabis, will be hard to track.\u201d<\/p>\n<p>The report said that when people consume cannabis, their bodies process it into metabolites that are later eliminated from the body and can show up in wastewater.<\/p>\n<p>It said this method of testing has been used in Europe since 2007 to report on people&#8217;s drug consumption in large cities.<\/p>\n<p>StatCan said sampling will continue through the spring of 2019.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>HALIFAX \u2014 A new study from Statistics Canada draws data from an unexpected source to suggest Halifax has the highest &hellip;<\/p>\n","protected":false},"author":44,"featured_media":57893,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[18,16],"tags":[],"class_list":["post-192134","post","type-post","status-publish","format-standard","has-post-thumbnail","category-news-ca","category-news","mauthors-alex-cooke","mauthors-the-canadian-press"],"_links":{"self":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts\/192134","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/users\/44"}],"replies":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/comments?post=192134"}],"version-history":[{"count":0,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/posts\/192134\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/media\/57893"}],"wp:attachment":[{"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/media?parent=192134"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/categories?post=192134"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/canadianinquirer.net\/v1\/wp-json\/wp\/v2\/tags?post=192134"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
