While some drug paraphernalia may cause legal issues that is not the case with Pipes. Even glass bongs are legal as long as it’s sold and used for tobacco use only. Pipes are not just used to smoke marijuana but tobacco and other products can be smoked in a Pipe as well.

If you want to get a Pipe then there is no problem with buying one. They are primarily designed for tobacco use but other products like marijuana are smoked in a Pipe as well.
