If you are truly cold smoking (no heat generation at all) I don't see why it wouldn't work. If you are "cold smoking" with heat (say at 160 degrees) then I wouldn't use it. Most plastic pipes are only rated for around 150 degrees. Dryer duct is a good cheap choice that is rated for higher temps. You can get a 10' section for $10.
