Well – that’s true. Head shops do sell bongs, pipes and everything else you can imagine. However, if you are arrested for having “too much pot” on you [even in some legal states], you could be charged federally for having drug paraphernalia. So yes – you can buy bongs and pipes everywhere, but owning it and getting caught with it will add criminal offenses on your record, increasing sentencing as well as potential fees the government shanks you with after they arrest you.
