So we know that cigarette companies use lots of additives and flavorings, how come that cigarette tobacco is so flacky and dry ? I know that for example glycerin is sticky and PG not so much.Also several types of sugars are added to the cigarette tobacco but none of it seems to leave the cigarette tobacco sticky compared to pipe tobacco.Do the sugarw actually react with the tobacco leaves ? I've read that heating causes the tobacco pores to open up and absorb some of the casings, whats the science behind it ? I dont understand how adding pg, glycerine, sugars, honey etc to the tobacco leaves no stickiness in the cigarette.
