While California works with pesticide limits, Canada has taken a stricter zero-tolerance stance. Since legalizing cannabis in 2018, Canada has required testing for 96 pesticides—30 more than California. If any trace of these chemicals is found above the detection threshold, the product fails. While this ensures cleaner cannabis, it also forces growers to rely on indoor and greenhouse cultivation to avoid pesticide drift. However, this method isn’t perfect either. Indoor grows require significant energy and water use, raising costs that trickle down to consumers. Canada’s tough rules show what’s possible, but they also highlight the environmental and economic trade-offs of enforcing zero tolerance. Learn more about Pure Roots
