WELLINGTON, New Zealand — New Zealanders voted to legalize euthanasia in a binding referendum, but preliminary results released Friday showed they likely would not legalize marijuana. With about 83% of votes counted, New Zealanders emphatically endorsed the euthanasia measure with 65% voting in favor and 34% voting against. The “No” vote on marijuana was much closer, with 53% voting against legalizing the drug for recreational use and 46% voting in favor.
