Cigarettes receiving mass popularity in the early 1900s led to many being concerned that smoking may not be healthy. Warnings of cancer and stillbirths were spread across the country by anti-tobacco movements, which causes multiple states to enact bans on cigarettes. Nearly all states banned the sale of cigarettes to minors, while multiple banned the sale to adults (Marshall 253). This is the first time the American public was made aware of what cigarettes can do to one's health, which caused the perception of smoking to begin to change. With this change of perception, the tobacco companies had to begin using manipulative marketing methods to distract the public.
