The Puget Sound area is known for a lot of things. The beaches. The outdoor activities. And, of course, the pot.
K5News reported on a recent wastewater study which showed that “while sales of legal cannabis increased rapidly from 2014 to 2016, roughly 70% per quarter, there was only a small increase in the amount of THC metabolites detected in the waste stream, indicating that most users switched from illicit markets to legal ones. The research team did also see some growth in consumption — noting a particularly large spike at the end of 2016.”
According to the study, western Washington is a world leader in cannabis consumption. “We are part of an international study… with 60-80 other cities around the world. And according to wastewater, the Puget Sound area has the highest cannabis use per capita, even over Amsterdam.”
Led by Dr. Dan Burgard, a team of researchers at University of Puget Sound and University of Washington analyzed wastewater samples collected in western Washington from 2013 to 2016.
The researchers used new methods to detect trace amounts of THC metabolites in the waste stream – that’s what leaves your body and gets flushed down the toilet after cannabis consumption of any kind, whether smoked, vaped, or eaten.
Gee, and I thought it went up when I moved from Utah. I certainly chose Tacoma as the right place to call home.
