Colorado school districts will soon be able to apply for grants of up to $50,000 to help their students reduce cell phone use during the school day. State Attorney General Phil Weiser announced the “Smartphone Challenge Initiative” Friday in the library of Grand Junction High School. The program is funded with money from the state’s $31.7 million lawsuit settlement with e-cigarette manufacturer Juul Labs Inc. The initiative is the second school district grant program aimed at improving student mental health funded with Juul settlement dollars.
