Yeah, you can get cancer from chewing tobacco. A guy I went to school with lost part of his lower jaw to cancer due to his constant chew habit.
That stuff has carcinogens in it period. Not just when burned and inhaled.

Can one overdose on nicotine?
Nicotine is highly toxic in humans at high doses and deaths have been caused by ingesting water that had cigarettes steeped in it. In non-tolerated users, 1-4 mg of nicotine can cause a sense of overstimulation, nausea, vertigo, and dysphoria. Nicotine poisonings occur from skin contact with tobacco plants, contact with nicotine-containing pesticides, after intentional oral ingestion (suicides), and young children accidentally eating tobacco products. The U.S. Center for Disease Control reports the "fatal human dose has been estimated to be about 50 to 60 mg [Lazutka et al. 1969]" (CDC.gov).
