A Platte County deputy stopped the vehicle on Feb. 15 after observing several traffic violations.
During the stop, the deputy said he smelled an odor of what he believed to be burnt marijuana.
The driver, Joshua A. Quinn, 25, of Castle Rock, Colorado, gave the deputy permission to search the vehicle. That's when the deputy discovered 67 marijuana plants, nearly 9 pounds of marijuana and other drug paraphernalia.
Quinn and a passenger, Joseph D. Willis, 53, of Auburn, Massachusetts, were arrested and now face charges related to the possession, distribution, delivery and manufacturing of a controlled substance.
Quinn's bond was set at $25,000 cash. Willis is being held on a $35,000 cash bond.
They are expected in court on March 4.
