Yep, those little packs of cigarettes were an investment in the future for Big Tobacco.
Oh it's better than than that (Or worse) I think it was Reynolds (The company that had the director say "That'll get 'em hooked" and the director who stored meeting minutes at his mistresses house.. BIG mistake) In a cooperative deal with the Government they found a way to seriously increase the nicotine content of the weed.. The Sales speech was "You won't need to ship as many" and thus you will save money.
What really happened? Increase in the addictiveness = more sales of course and more profit and more death.
Normally I'm not all that bothered by a smoker near... But those high-potency weeds choke me up even if you go outside, smoke, then come back in just what clings to your uniform (clothing) is enough to give me trouble breathing.
