Pennsylvania’s cigarette tax is going up today by a buck per pack, giving smokers one more reason to quit or cross the border to buy. The tax will be $2.60 starting today, up from $1.60. It’s the largest-single increase on the state’s smokers since Pennsylvania first imposed a cigarette excise tax in 1935. For Democratic Gov. Tom Wolf and the Republican-controlled Legislature, it was a step toward addressing a long-term deficit.
