http://www.thompson-morgan.com/flow...ardy-annual-seeds/nicotiana-suaveolens/4675TMIt has high amounts of nornicotine (approx. 16 times more than tobacco) and anabasine (approx. 4 times more than tobacco). It may be dangerous to smoke it.
I know that there're more than 20 wild tobacco varieties in Australia but the best one (i think), because of the health issues, is N. amplexicaulis. Other ones really have large amounts of harmful compounds.
