BOSTON -- States are losing millions in tax dollars as more people buy cigarettes from online vendors who routinely ignore a federal law requiring them to report sales to local regulators, a new report says.

According to the Associated Press, the trend could undercut efforts by cash-strapped states to raise revenues by hiking cigarette taxes. In Massachusetts lawmakers recently approved a 75-cent hike on a pack of cigarettes, a move officials hope will bring in an extra $190 million annually.

FAIRFAX, Va. -- ExxonMobil is joining with the Attorneys General of 43 states, two territories and the District of Columbia, to launch several new initiatives to stop sales of cigarettes to minors at all its company-operated stores.

ExxonMobil is one of the first in the industry to take the lead in initiating new curbs on minors smoking, which includes more intensive staff training, internal and external reviews, monitoring of sales practices and the removal of all self-service displays of tobacco products at service stations.
