I watched this last night. First half of the show was primarily dedicated to cigarettes, how they're made, etc. All I have to say is WOW. I mean I knew they added stuff to cigarette tobacco, but some of the stuff they listed! In addition, they use 'recycled' tobacco for cigs. Yes, the stale stuff that comes back from the stores AND scraps from the floor.
It was interesting that they chose the Fuente Opus X as the example for aging tobacco, rolling, etc. Had Carlos Jr on for several segments on the process. Also spent a few minutes on pipe tobacco, and smokeless tobacco.
I think the show was well done. There's only so much info you can stuff into an hour, and for the most part, it was educational and interesting. Surprisingly they spent very little time discussing the medical issues associated with tobacco use. Primarily pointed out that cigar/pipe users don't typically inhale, resulting in fewer cases of lung disease.
This was a great show for someone who isn't aware of the history of tobacco, or it's many uses. For most BOTL's, I would assume the show was really just a teaser, as there were so many things that could have been put into the show had it been a little longer.
Keep looking at the History channel, as I'm sure it will be on again sometime in the near future.
