Teen smoking climbed in Finland, for instance, after it banned tobacco ads in the late '70s. The same thing happened in Sweden after tight ad rules were imposed.

Even the vaunted ad restrictions could have worked to their benefit, trimming huge marketing budgets while freezing out new competitors.
