Colorado marijuana regulators are considering changes to lab testing procedures due to concerns about sample manipulation. The proposed changes, discussed at a recent policy forum, would prevent marijuana manufacturers from selecting their own product samples for mandatory contaminant testing. Instead, the Marijuana Enforcement Division may require independent labs or vendors to collect samples. This shift aims to address complaints that some companies submit unrepresentative samples to pass tests, while selling potentially contaminated products. A recent investigation highlighted numerous violations of testing rules, including sample adulteration and unauthorized chemical treatments. Officials acknowledge that Colorado's regulations have fallen behind other states, prompting this move to strengthen oversight and ensure product safety.
