阅读下面材料并回答问题。
(一)素材:
作为《烟草控制框架公约》的缔约方,我国承诺2011年1月9日前在室内公共场所和室内工作场所实现100%禁烟。但时至今日,我国仍无一部国家级的无烟立法,且由于相关部门政企不分、烟草涨税不涨价、烟草文化难以改变等原因,履约5年内,不仅全民吸烟率没有下降,二手烟的受害者却在3年内增加了2亿人。
中国于2007年成立了由8部委组成的《烟草控制框架公约》履约工作部际领导小组,其中工信部为组长单位,组员单位包括国家烟草专卖局、卫生部、外交部等部门。工信部既是主导部门,又管理着国家烟草专卖局,集两个对立的角色于一身,作出的决定难辨是企业决策还是政府决策。
目前,我国不仅没有一部专门针对公共场所禁止吸烟的全国性法律,连《广告法》和《国家烟草广告管理暂行办法》也并未全面禁止烟草广告。变相的烟草广告不仅未被禁止,且其触角还伸向公益领域。中国控烟协会统计显示,2009年9月到12月间,52家烟草企业捐赠公益及文体活动达79起,覆盖全国40个县市;2010年11月,国家烟草专卖局还为中国妇女发展基金会设立了金叶基金,并捐款1000万元用于支持两个公益项目。
但时至今日,烟草专柜上仍摆满了印有 * * 、大熊猫、中国龙等图案的“美丽”烟盒,与国外烟盒包装上的烂嘴、烂肺、骷髅等恶心图案相比,上面一行不太抢眼的“吸烟有害健康”警语显得不痛不痒。
每年都有一些纪念日,“无烟日”这几年被强调得十分突出。原因是中国的烟民数量庞大(3.5亿),已经接近所有发达国家烟民数量的总和(4亿)。因此,每到这个日子,反对吸烟的人就会拿出新的例证来,证明吸烟对健康的伤害、对他人的伤害,并要求拿出措施,在一些场所严禁吸烟。
多年来中国烟草税收一直是国内最大的单一税源,在某些省份,烟草税收已经占到财政收入的70%。烟草业的就业人数约有6000万人。看到这些就会明白,戒烟难,不仅仅难在烟民,也难在政府。吸烟有害健康,但烟草又是我国的重要财政收入,真是个两难问题。
吸烟的人是有自己的苦衷与无奈的,他们往往比别人更清楚香烟的危害,之所以还吸,是因为有了生理依赖。
