Las Vegas City Council to Consider Medical Marijuana Plan

A town near Denver, Colorado has been asked not to drink the water in their town due to the possible contamination of THC in their water supply. Police believe that the substance may have been introduced in the water system at one of the town’s five water wells, they also believe this was not an accident and purposely inserted in their water.

"There were signs of tamper, forced entry into what would've been the raw water supply.” Says Captain Michael Yowell from the Lincoln County Sheriff’s Office.

A company that conducts routine employee drug tests discovered the THC in the water. Even though Colorado allows legal sale of medical and recreational marijuana, counties and businesses can decide whether or not to allow it.
