I don't know what the laws are on possession, but before marijuana was legalized it was far, far easier to buy a bong than the weed to smoke in it. I'm wracking my brain to try to think of a piece of drug paraphernalia that is illegal to sell or illegal to possess in the absence of the drugs themselves.

In the state I live in it's illegal to to be in possession of any paraphernalia. Thats why you cant buy a bong anywhere, but can buy a water pipe at every corner store headshop.

That being said it's a petty misdemeanor that does not result in any jail time until your third infraction.
