Gov. John Hickenlooper has signed a bill establishing criminal penalties for the illegal use of synthetic drugs known as bath salts.
Hickenlooper signed the bill Thursday.
Earlier this year, health authorities said a 19-year-old Grand Junction man who was acting violently under the influence of a substance marketed as bath salts was strangled when his friends tried to subdue him. Friends took him to a hospital, where he died.
Congress is considering legislation to ban chemicals marketed as bath salts.
