[Q]: Paragraph: With the scientific data about the health risks of smoking and information about the effect of smoking on troop readiness , in 1975 , the United States Department of Defense discontinued the inclusion of cigarettes in K - rations and C - rations . By 1978 , the Department of Defense had implemented basic smoking regulations , including the designation of smoking and nonsmoking areas . In 1985 , the Department of Defense conducted a study that revealed that smoking rates of military personnel ( 47 % ) were significantly higher than that of US civilians ( 30 % ) and concluded that smoking had a negative effect on troop readiness . The report also cited an estimated tobacco - related healthcare costs as high as $209.9 million , and recommended potential methods to curb smoking in the military , including the elimination of tobacco products from stores , raising tobacco prices to civilian levels , and the implementation of an educational program to discourage smoking . In 1986 , the DoD Directive 1010.10 was issued by Secretary of Defense Caspar Weinberger , who announced , '' an intense anti-smoking campaign ... at all levels of all Services . '' It established a policy on smoking and other health risk behaviors such as alcohol consumption . The policy banned the use of tobacco during basic training , increased the number of designated nonsmoking areas , and prohibited health care providers from smoking on duty . The goal of the policy was to reduce all tobacco use rates to below that of civilians , and to reduce personnel and active duty rates from 52 % to 25 % by 1990 . In 1992 , the DeCA Directive 40 - 13 policy prohibited commissaries and exchanges from participating with promotions by tobacco manufacturers directed specifically at military personnel , and required commissaries to stock cigarettes in the back . In 1993 , the USS Theodore Roosevelt ( CVN - 71 ) became the first smoke - free Navy ship . By 1994 , the Department of Defense had implemented Directive 1010.15 which banned smoking in workplaces , designated outdoor smoking areas , and created the precursor of an education program that sought to distribute information to new personnel on the health effects of smoking and to encourage smokers to quit . Executive Order 13508 in 1997 banned smoking in all government - owned , rented , or leased interior spaces , but the Department of Defense approved a three - year phase - in period for their facilities and eventually implemented the ban on December 7 , 2002 . Despite these attempts , by 1988 , the smoking rate had only decreased to 42 % and far exceeded the rate of civilians . And although prevalence did decrease to 29.9 % from 1980 to 1998 , it has increased since then and appears to still be increasing .

[Q]: Paragraph: Armed conflict began in 1775 . In 1776 , the Second Continental Congress declared the independence of the colonies as the United States of America . Led by General George Washington , it won the Revolutionary War with large support from France . The peace treaty of 1783 gave the new nation the land east of the Mississippi River ( except Canada and Florida ) . The Articles of Confederation established a central government , but it was ineffectual at providing stability , as it could not collect taxes and had no executive officer . A convention in 1787 wrote a new Constitution that was adopted in 1789 . In 1791 , a Bill of Rights was added to guarantee inalienable rights . With Washington as the first president and Alexander Hamilton his chief adviser , a strong central government was created . Purchase of the Louisiana Territory from France in 1803 doubled the size of the United States . A second and final war with Britain was fought in 1812 , which solidified national pride .
