No Marijuana Chemical in Colorado Town’s Water

A Colorado town’s water supply is not contaminated with the chemical in marijuana that makes people high, officials say.

Laboratory tests showed there is no THC in Hugo’s water, contrary to what earlier field tests suggested, according to the Lincoln County Sheriff’s Office, CNN reported.

Saturday’s announcement that the town’s water was free of THC ended a two-day advisory for its 700 residents, who were told not to drink, cook or shower with the tap water.

“We are happy to announce that the water advisory is canceled immediately,” the sheriff’s department said, CNN reported.
