Thank you for Smoking
Thank you for Smoking is a fantastically biting satire movie on this very subject along with the other disciples of Beelzebub, firearms and alcohol.
If you have not seen it, I strongly recommend you do, a great speech by J.K Simmons in the movie:
"People, what is going on out there? I look down this table, all I see are white flags! Our numbers are down all across the board. Teen smoking, our bread and butter, is falling like a shit from heaven! We don't sell Tic Tacs for Christ's sake. We sell cigarettes! And they're cool and available and addictive. The job is almost done for us!"
