The 750 or so residents of Hugo, Colorado, are being warned not to drink, cook with, or bathe in the town's water for the next two days, the Denver Post reports. That's because officials have detected evidence of THC in the water supply. It's unclear how the THC got into the water, and there are no commercial marijuana operations in the county. According to CBS Denver, it's not clear how much THC is in the water and no one has shown symptoms. But officials are using "an abundance of caution." Fresh water is being brought in for residents. But not everyone is so concerned. “I might have to go drink some water,” Hugo's former mayor tells the Post. (More THC stories.)
