  This is a sequel of our previous work, arXiv:2209.09686, on the development
of derived contact geometry, in which we formally introduced shifted contact
structures on derived stacks and proved some results for $k$-shifted contact
derived schemes, with $k<0$. In this paper, we extend these results from
derived schemes to derived Artin stacks. In brief, we first show that for
$k<0$, every $k$-shifted contact derived Artin stack admits a contact Darboux
atlas. Secondly, we canonically describe the symplectification of a derived
Artin stack equipped with a $k$-shifted contact structure, where $k<0$. Lastly,
we give several constructions of contact derived stacks using certain cotangent
stacks and shifted prequantization structures.
