The LA Times ran a Holiday Gifts section in todays paper that featured a hand-held smoker by PolyScience that allows for finishing foods with cool smoke. The link below takes you to a web site that offers the gun for $82.00.
Check out the link to the videos of the gun in action. They say the gun is also great for smoking cheese and martinis. You can even do cigar flavored drinks.
Looks like it could have some recreational use applications, as well.
