What is this "indoor smoking" you describe. I'm a patio/garage/yard smoker only and with only that perspective, I have no issues. It hit 99 degrees yesterday in Maryland. I was in the garage working on my old Charatan estate smoking some Troost, I had a fan running, so no problems. Well, only that I have to remember not to bend over my drill buffer rig with the pipe when the unit is running, it gets a little messy....
