HARTFORD (AP) — Gov. Dannel P. Malloy has signed into law the latest legislative effort to combat opioid abuse in Connecticut.

This year's bill, which he signed during a ceremony Friday at the Legislative Office Building, limits first-time prescriptions for adults to seven days. That change will take effect starting July 1.

The bill also requires cities and towns to amend their emergency service plans by Oct. 1 to ensure first responders are trained and equipped with drugs to help reverse opioid overdoses.

Malloy was surrounded by lawmakers, advocates and families who've lost loved ones to drug abuse. They included Sue Kruczek of Guilford, whose 20-year-old son Nick, formerly of Madison, died in 2013 from a heroin overdose. He previously took pills.

Holding up a picture of her family, Kruczek said the seven-day prescription limit will help save lives.
