Five Larimer County residents have been indicted on charges alleging they played a role in efforts to make or distribute synthetic marijuana known as Spice.
The five were advised in U.S. District Court in Denver on Monday of charges against them. They are due to be arraigned Thursday.
Investigators say members of the group got ingredients from China and San Antonio and would sell the finished product in northern Colorado.
