A law that blocked tobacco from being sent to American soldiers serving in combat zones will soon be revised.The PACT Act took effect in June. It was meant to keep tobacco out of the hands of minors and required anyone mailing tobacco products to send them through tracked and confirmed Express Mail.But Express Mail cannot go to many foreign combat zones. Postal service spokesperson Greg Frey says the rules will be changed later this month so tobacco can be sent to soldiers through a different type of mail."We have made an exception at this point to allow for priority mail with delivery confirmation because of the sensitive nature of serving those brave Americans that are defending our liberties overseas," he says.The exemption takes effect on the 27th. Frey says it only affects mail to soldiers and not civilian-to-civilian packages.
