  Latest results on $\beta\beta 0 \nu$, $\beta\beta 0 \nu\chi^0$ and
$\beta\beta 2 \nu$ decays of different isotopes from NEMO-3 double beta decay
experiment are presented. In particular, new limits on neurtinoless double beta
decay of $^{100}Mo$ and $^{82}Se$ have been obtained, $T_{1/2} > 4.6\times
10^{23}$ y and $T_{1/2} > 1\times 10^{23}$ y, respectively. A possible next
step with SuperNEMO detector is discussed.
