Advertising vs packaging?

Which works better at getting the message across to teenagers ... pastel-coloured, fruit-flavoured cigarettes in packs which illuminate under fluorescent lights OR pictures of people whose mouths or limbs are affected by cigarette-related diseases and/or graphic representations of the chemicals inhaled while smoking cigarettes. Tough one isn't it? Which is probably why there are moves afoot to ban the funky packaging ... although I would also appreciate it if they would pull the graphic ads as well - or work out a way of them being visible only to current smokers. Wouldn't that be interesting - truly targetted marketing!
