This is probably the most insane advertisement I have ever seen. Everyone knows cigarettes are unhealthy, but back then very few people knew. And when people started doubting such scientific facts, advertisers start to pull of such stunts. Showing a doctor smoking a cigarette sends out a wrong message to the whole world; branding cigarettes as a safe product. This might even influence young children to start smoking at an early age causing disastrous effects to their lungs.
