cigarette labeling and advertising act of 1965 Federal & 1965 Lucky Strike Cigarettes New

This may be explained by the development oftolerance

Countries that do not yet have pictorial warnings, such as the U.S., now have new evidence that should help their efforts to mandate pictorial warnings on all cigarette packs. Study limitations include: 1) not knowing what effects pictorial warnings may have over a longer period of time, and 2) participant self-selection possibly resulting in a study population with a greater interest in quitting smoking than the general population

These effects extend far beyond those initial withdrawal days and early recovery wins

Smoking rates in the general population have declined substantially over the last 40 years
