Years ago when Teachers Smoked in Class and I had a Company repairing Apple II, Research Machines and BBC micros the damage from Cigarette Tar was staggering...
I don't know about "biohazard", but it can certainly be nasty. It's no wonder either that it's a PLUS point in Car and Electronic Gear sales when they say from a "non-smoker" home.
I have always wondered can the tar vapour or smaller volatile particles get in to the HDD surface via the breathing hole filter? HDDs are absolutely not hermetically sealed.
