New Law Says Medical Marijuana Sold From Oregon Dispensaries Must Be Tested For Pesticides

Will also need to be tested for mildew and mold

Oregon's new law creating a registry of medical marijuana dispensaries comes with a key provision aimed at protecting patients: cannabis sold in these establishments must be tested for pesticide, mold and mildew. 

The requirement represents the latest frontier in states' evolving approach to regulating marijuana. Twenty states, and Washington, D.C., allow marijuana for medicinal use, but Oregon is among only a handful that require cannabis testing. Nationally, advocates have lobbied states with medical marijuana laws to mandate lab tests for a range of impurities and even potency, arguing that consumers deserve detailed information about the drug before consuming it.
