LOOPHOLES & PITFALLS:
Bang or Bong, you cannot have both!
It is that simple. Until such time as the Federal Government removes marijuana from Controlled Substances Act as a Schedule I controlled substance, you must choose either guns or weed. If you choose both, you face 10 years in Federal Prison if caught. It does not matter at all that New Jersey has legalized marijuana. The Federal law is an entirely separate jurisdiction.
