There's not a hint of metal anywhere on my grinder after much use. It must just be the one you own.

Also chances are the wood used to make your wooden grinder has been chemically treated when the wood was being dried, and to make it last longer - wetting agent, dry-aid, varnish, formaldehyde, sodium benzoate, etc.

Also, a lighter never gets hot enough to sublimate aluminum or steel. It's impossible to inhale any vapor from thier use.

Look around your house. Your cookware, parts fo the element on your stove, the element in your kettle. They are all made from steel. There is a reason for this - it is inert and under operating temperatures do not get hot enough to sublimate gaseous metal - and thats based on real life scientific application, not stoner psuedo-knowledge.
duckfool Reviewed by duckfool on . Metal Grinders=metal alloy in your lungs. I just wanted to do a sort of follow up on that kief grinder thread. The common spacecase metal 3 chamber grinders create mass amounts of friction when used. For all who own one, unscrew the middle chamber,and run your index finger across the main threading of the grinder. When I owned one, and did this ,a massive amount off aluminum shrapnel came off the threading . Mine was a 130$ spacecase grinder, I've seen low end 50$ kief catchers ,and can only imagine..
