Costs are soaring surrounding Massachusetts' healthcare law and lawmakers are weighing a dollar-a-pack hike in the state's cigarette tax to help pay for a enrollment in the law's subsidized insurance plans.

California attempted their own healthcare expansion, but the program failed to get out of a key Senate committee.
