Local sales taxes push up the overall sales tax to more than 8% in Yonkers and New York City and on Long Island.But the biggest impact is expected to be hundreds of miles away from the Empire State, where tobacco taxes are low.

Increased taxes on tobacco will lower its demand. Revenues and profits margins are affected, because tobacco companies will either decrease taxes or raise prices in order to sell their products."
