i don't know.
i almost *never* smoke it. lungs can't handle it. i chew it.
but i will say this. switching from store bought chew to the stuff i grew was hard. even though i was getting plenty nicotine from the home grown stuff, there was something else my body/brain was craving. eventually that craving went away and i found that with my home grown stuff i could sort of take it or leave it on any given day. very different from the hard core "gotta-have-it-all-the-time level of addiction" that i had with the store bought stuff. but i also missed that hard bump that i was getting from the store bought stuff and eventually went back to the store bought stuff. looking forward to getting back off that and back onto my homegrown stuff after this harvest.
so, yeah, i think big tobacco companies are in fact doing something to the stuff they are selling to juice it up, and, yeah, i suspect my homegrown stuff is not as bad for me as the store bought stuff
but i don't really know
