Why did the ratio of female to men of smoking increase between 1965 and 1995?

The increase in the ratio of female to male smokers between 1965 and 1995 can be attributed to several social and cultural shifts. During this period, societal norms regarding women's smoking began to change, with smoking being marketed as a symbol of liberation and empowerment for women. Additionally, public health campaigns and anti-smoking regulations primarily targeted men, allowing women to adopt smoking behaviors without the same level of stigma. As a result, more women began to smoke, contributing to the rising ratio.
