Fourth-hand smoke hides under the bed

Just to make it clear, The South Bayview Bulldog doesn’t smoke, never has and doesn’t like the habit. But there is a limit to how much third-hand-smoke baloney we’ll consume. Now some people in Riverside, California have put mice in cages “exposed to third hand smoke” and  found the poor creatures have suffered organ damage.  It’s a little hard to follow but the suggestion seems to be that third hand smoke sticks to things and gets even nastier than it was, sort of like cranky old curmudgeons of the human type. Maybe, but unless homosapiens are about to start licking third-hand smoke off the furniture it seems like a lot of worry about not much. We’re waiting to hear that fourth-hand smoke hides under the bed and infects your underwear at night. You know. Could be a problem.
