I have seen opinions from U.S. poskim from many years ago that rule that marijuana use should be forbidden by Jewish law on the basis of "dina d'Malchusa dina" ["the law of the land is the law"]. These rulings were made at a time when marijuana was universally illegal in the U.S. Now that this situation is changing and recreational marijuana is becoming legal in state after state, have there been updated rulings either way?
If any posek rules that it should still be forbidden by Jewish law, even in a place where it is legal according to secular law, I would be curious to hear on what basis the posek distinguishes between recreational marijuana and "recreational alcohol". And if they cite the concern that smoking may be a health risk, even for marijuana, would they allow food products containing marijuana?
