Australia is ahead of the curve about cigarettes. They now require ¾ of the front of all cigarette packages to have graphic health warnings. The other ¼ is plain-brown with the name brand appearing in a standard size and font without any logos.
Some researchers conducted a survey during this transition time. Without boring you with the details, they found respondents who smoked cigarettes in plain-brown packaging indicated their smoking satisfaction was less than it was a year earlier.
