LOUISVILLE, Ky. (WDRB) -- After a month-long break, Kentucky lawmakers returned to Frankfort Tuesday for part two of the 2015 legislative session.

Lawmakers have a lot to do in a short period of time.

Among the top priorities is an anti-heroin bill. The Senate passed a bill last month designed to improve treatment for addicts and toughen penalties for heroin dealers. The question is whether the House and Senate can agree on a final bill.

Another issue, is the public pension system. It's under-funded by billions of dollars. House Speaker Greg Stumbo has proposed borrowing more than $3 billion to help shore up the system.

Other bills to watch for are the proposed Local Option Sales Tax, a statewide smoking ban, a medical marijuana bill and a bill focusing on the state gas tax.

The rate is tied to the wholesale price of gasoline, and as the price has gone down, so has revenue from that tax, leaving the highway fund short of cash.

This session includes just 30 working days and ends March 24.
