Members of the Georgia House have begun what promises to be a long day of debating and voting on bills.

Monday marks the 30th day of the 40-day legislative session known as “Crossover Day,” so called because it is the day bills must pass at least one chamber and “cross over” to the other or be lost for the rest of the session.

House Speaker David Ralston, R-Blue Ridge, gaveled the session to order a few minutes after 10 a.m.

“Day 30,” he said dryly. “Time to get to work.”

The House began the day with 17 bills on its debate calendar, but many more likely will be added as lawmakers push to get their bills heard before midnight.

Among the bills that may get a vote in the House is House Bill 885 which would allow the use of medical marijuana for certain conditions and House Bill 707 which would bar any state or local government or agency from operating a health care exchange or navigator program allowed under the Affordable Care Act, also known as Obamacare.
