Why are you worried about your grinder? If you clean it out and make sure there's no weed/keif in it you should be fine right? Hell, grind up some tobacco with that bad boy before you get on the plane...herb grinders aren't illegal, just the stuff that goes in them.
Rapidfire187 Reviewed by Rapidfire187 on . Flying with a grinder So I'm flying home tomorrow and I want to bring my grinding back with me. I'm going to be carrying my bag on so think its a bad idea to put the grinder into 5 or 6 plastic bags and put it in my carry on? Rating: 5
