If it was skin DCI you were worried about then exposing skin to hyperbaric O2 in the drysuit might be helpful
.
I suspect that the absorption of suit inflation gas is negligable, otherwise argon users would be narced off their faces.
Exposure to O2 might accelerate perishing of seals etc but apart from that it's probably not a big issue.
Personally I wouldn't recommend smoking after your dive though, particularly if posterior "off-gassing" has occurred into the suit during ascent. Might go off with a bang.
