Do Graphic Images Change Behavior?

EDITED SMOKINGDo  graphic images  change behavior?  I took this photo last week  of a cigarette pack in Australia. Canada was the first to introduce picture warnings in 2001. Graphic images are now used on tobacco products sold in over 23 countries including Brazil, Canada. India, New Zealand, Singapore, Venezuela, Thailand and Uruguay.

As of 2013, all cigarette packets produced for the Irish market will now carry graphic photographs with a strong health warning. The Irish Heart Association says that brand imagery is used to target young people and that 78% of smokers take up the habit before the age of 18.

Do you think graphic images should be used on tobacco products in the USA?
