If completely clean and in my checked bag, can I get into any kind of trouble for doing this? I figure it really could be used to grind anything, so I don't see a reason I shouldn't, just want to hear your opinions/experiences
If it's cleaned extremely well you can probably get away with it. But if they see it at some point they'll probably give you shit for it.
If it still smells like ganja, the drug dogs are most likely going to smell it. My Uncle was once out flying when he got marked by a drug dog. They searched the shit out of him, but didn't find anything. Turns out the dog had marked a fanny-pack type thing that he occasionally carried a joint in when he went out biking, and the last time he had used it was about 4 years back. Those dogs have sensitive fucking noses.
a german shepherd tried to attack my 2 year old son in the airport, and the officer had the nerve to smile ate me. mighta been a bomb dog, mighta been a drug dog, almost gave me a heart attack and very nearly got my hubby in trouble, who was holding him. his instinct was to knee the animal, but if he had we would have been detained and he would have gone in for assaulting an officer. use your damn fingers, don't fuck around.
Well it's common sense. A bong could be used for many things too but we all know what people use them for.
