I think tobacco is the Antichrist. I don't like anything about it- and I used to wholesale premium handrolled cigars in Florida.
The American Thorassic Society, whose members are surgeons who specialize in disorders of the chest cavity, recently completed a multi-decade study of the cancer risks of smoking. Smoke tobacco- by itself or with weed, makes no difference statistically- and your risk of mouth, throat and lung cancers go up by 23 times over the baseline. Smoke just weed and your cancer risk increases by... nothing.
So don't smoke tobacco, save your lungs for the good stuff! Nuff said.
