The title compound, C~11~H~16~N~2~ ^2+^·2Cl^−^·H~2~O, is a novel conformationally constrained tricyclic analogue of nicotine, in which the pyridine and pyrrolidine rings of the latter are bridged by a CH~2~ group. As result of this bridge, these two rings are no longer approximately perpendicular as
