I don't think they can, my mother goes to a place where they use pure tobacco and you make your own cigs. They have machines that YOU do it, but they walk you through it. Since you're doing it yourself it's not taxed like regular cigs, it's actually pretty cheap she said it's about $25 a carton (this is in South Floride where premium cigs are about $60 a carton). The plus side is that there's have no nicotine and it's pure tobacco so less or no chemical (not sure but pretty sure there isn't any chemicals), but you still get tar. I was gonna go that route to quit but then stumbled upon eCigarettes and chose that route. My mother was a 2-3 pack a day 100s smoker, it took her 3 months to get off the nicotine.
