Can I buy a bong or a pipe?

Yes.

 

Can you possess it?

No.

 

This is a real head-scratcher for most of us.

 

A store can sell you what is obviously a device intended for the consumption of a controlled substance, but you can't possess paraphernalia.

 

It's a distinction without a difference to argue that it can be used for a non-controlled substance. That's not the issue. The only question is can it be used to ingest a controlled substance.

 

If it can be used to consume a controlled substance it is a narcotic implement, also known as drug paraphernalia.
