Hmm... To be honest it may not have chipped the paint, it kinda looks like some of the finish on the outside has come off but that might just be general wear and tear (it does see a fair amount of use) and I'm panicking for no reason. Much like you mentioned in the post I'm generally super worried about accidentally smoking paint chips so I could be being over cautious, I've certainly never seen anything in with my ground up weed. Appreciate the advice, I'll give some thought to all my options I guess, hope you manage to find a good replacement grinder!
