In larger amounts it is thought to be [[Teratology|teratogenic]] in swine.<ref>{{cite web | title = Notes on poisoning: Nicotiana tabacum | work = Canadian Biodiversity Information Facility | publisher = [[Government of Canada]] | date = 2008-03-18 | url = http://www.cbif.gc.ca/pls/pp/ppack.info?p_psn=186&p_type=all&p_sci=sci&p_x=px | accessdate = 2008-05-01}}</ref> ==Pharmacology== Anabasine is a [[nicotinic receptor]] [[agonist]] toxin and [[cholinesterase inhibitor]] which acts upon the [[nicotinic acetylcholine receptor]]s. Anabasine is a minor tobacco alkaloid which can be used as an indicator of a person's exposure to tobacco smoke.<ref>{{cite journal | author = P. Jacob, 3rd, L. Yu, A. T. Shulgin and N. L.

The intravenous LD50 of the (+)-R-anabasine rich fraction was 11±1.0 mg/kg and that of the (-)-S-anabasine-rich fraction was 16±1.0 mg/kg. The LD50 of anabaseine was 0.58±0.05 mg/kg. Anabaseine was significantly more toxic in the mouse bioassay than S-anabasine (27-fold) and R-anabasine (18-fold).
