Upload & Sell: Off
Agreed. One of my first purchases from FM, many years ago, came from a smoker who didn't disclose it. Nasty smell, and there was a horrible yellow coating on the box and lens. Sold it at a big loss and have made sure since then to always check w/ the seller first to make sure it hasn't been exposed to cigarette/cigar smoke. I also put "From a nonsmoking household" on anything I post so that people will know the gear I am selling is fine.
Sadly smokers don't realize how nasty cigarette smoke makes them, and everything around them, smell. Not to mention how bad nicotine is for camera gear (as well as their lungs).
Disclaimer: my father died a very painful death, as did 2 of my family friends, from lung cancer so I'm a little bit biased. And I had surgery 3 times on my vocal chords to remove benign tumors caused by breathing second hand smoke as a child.
