In the ever-evolving landscape of Colorado’s marijuana industry, concerns about pesticides have recently taken center stage. Denver’s 19th batch of marijuana products was voluntarily recalled due to the potential presence of harmful pesticides, prompting a closer look at regulations governing pesticide use in cannabis cultivation. As the state grapples with these concerns, lawmakers are considering legislation to address the issue.

While the recalled products have not been linked to any reported illnesses, lawsuits have been filed against prominent marijuana growers. In response, both Governor John Hickenlooper and the U.S. Environmental Protection Agency have become involved in efforts to rectify the situation.

The impact of pesticide concerns isn’t limited to traditional marijuana flowers. Products such as oils, waxes, edibles, and candies have also made their way onto the recall list, highlighting the need for comprehensive regulation in the industry.

One legislative proposal aimed at addressing this issue is Senate Bill 15. This bill seeks to establish statewide rules governing the types of pesticides that marijuana growers can use. Currently, a list of suggested acceptable pesticides consists of over 200 options deemed low-risk. However, this list is a fraction of the approximately 12,000 registered pesticides in Colorado, and the legal framework is needed to enforce compliance.

In addition to S.B. 15, lawmakers are exploring the possibility of creating a labeling program for marijuana products grown without pesticides. Like organic labels in the food industry, this program would provide consumers with a straightforward way to identify and purchase pesticide-free cannabis.

The primary concern surrounding these pesticides lies in their potential health risks:

• Myclobutanil: This fungicide, when inhaled, has been known to cause nervous system problems, as acknowledged by its supplier.
• Imidacloprid: An insecticide considered moderately hazardous, it poses risks of moderate toxicity when inhaled or ingested, according to the National Pesticide Information Center.
