I don't mean to laugh in your face, but LOL. Which BT exec fed you that? tobacco, IN ITSELF, releases A LOT of chemicals when burned. While it is safe to believe that BT adds chemical additives for the purpose of preservation/flavor/shelf-life/etc., tobacco alone does a pretty good job of releasing chemicals.
There are "additive-free" rolling tobaccos, but even those are still "tobacco" and therefore, when burned, will release chemicals. Even then, that has no bearing on the amount of nicotine in the tobacco. Because it's unfiltered (safe to presume) less of the nicotine is getting filtered out (as well as the chemicals), meaning the effect of the nicotine (and the chemicals, really) is greatly increased.
Also while I'm quoting you, what did you mean by this:
Cause ive rolled my own cigs with pipe tobaco and its much cleaner then what you get in a regular cigs. I could inhaled way more thus getting more nic.
What i wrote is self explanatory.
That other thing was my brain fart, so i fixed it.
