Summary of Effects

Posted 4:31pm Thu, 30/07/2009 by David

Warnings are a key, low-cost channel for informing people about the harms of smoking.
Warnings increase knowledge about harms of smoking.
Warnings lead smokers to think about the risks of smoking and to think about quitting, and these effects, in turn, are associated with future quit attempts.
Changing warnings regularly leads to increases in impact and salience.
Pictorial warnings are more effective than text-only warnings, probably because they are more emotionally arousing and present the harms of smoking in vivid and memorable ways.
Larger warnings are more effective.
Impact of warnings may be stronger in low-/middle-income countries, where there are fewer other sources of information about the harms of smoking.
