TRENTON, N.J. (CBSNewYork/CNN) – New Jersey’s right to die law goes into effect Thursday.

“Allowing residents with terminal illnesses to make end-of-life choices for themselves is the right thing to do,” said Gov. Phil Murphy at the time of signing the bill in April 12. “We are providing terminally ill patients and their families with the humanity, dignity, and respect that they so richly deserve at the most difficult times any of us will face.”

Physician-assisted suicide differs from euthanasia, which is defined as the act of assisting people with their death in order to end their suffering, but without the backing of a controlling legal authority.

‘Right To Die’ Advocate Barbara Hammer Passes At Age 79

CBS2’s Cindy Hsu spoke with the family of Herb Dunn, who wished to die with dignity for years.

Dunn died six years ago of pancreatic cancer at age 57. His wife, Debra, says his final weeks were unbearably painful and he wanted to die.

“Three times he said to me that he didn’t want to be alive anymore,” she said.

After Debra lost her husband, she started fighting to make it legal for terminally ill patients to end their lives. Last month, she testified in Trenton, N.J., and worked closely with the group Compassion and Choices, which is leading the effort.

There’s a long list of criteria for patients who want to receive the life-ending medication to end their life.

“You have to be an adult. You have to be deemed of sound mind by your physician,” Dr. Deborah Pasik, a right-to-die advocate, said.

You must be terminally ill with six months or less to live, and that has to be diagnosed by two medical doctors. The patient must sign a written declaration, witnessed by two people, that they’re acting voluntarily.

There are many critics against the law who believe this is doctor-assisted suicide, but with this law, the patient must be able to take the medication themselves.

“This is a self-administered oral medication in the form of a powder that’s mixed in a liquid,” Pasik said.

Debra Dunn says after years of fighting for this law, on Thursday, maybe she’ll get a sign from her husband.

“‘Thank you, Debbie. Thank you. You did good,'” she said.

States with “right to die” laws include Colorado, the District of Columbia, Hawaii, Maine, New Jersey, Oregon, Vermont and Washington.

Maine’s law goes into effect in September.

In addition, California and Montana has “right to die” protections in place mandated by court rulings.

Timeline Of “Right To Die” Legislation

June 1997 – The US Supreme Court rules that state laws banning physician-assisted suicide do not violate the Constitution in the case Washington v. Glucksberg. The court left the matter of the constitutionality of a right to a physician’s aid in dying to the states.

October 27, 1997 – Oregon’s Death with Dignity Act becomes law. Passed in a 1994 election with 51% of voters in favor, the law was delayed initially because US District Judge Michael Hogan issued an injunction and then ruled it unconstitutional. The Ninth Circuit Court of Appeals reversed the ruling and the injunction was lifted when the US Supreme Court referred the matter back to the state in 1997.

November 1998 – American pathologist and assisted suicide advocate Jack Kevorkian, known as “Dr. Death,” videotapes the death of Thomas Youk, submits it to CBS’s 60 Minutes and it is broadcast on television. The airing prompts murder charges against Kevorkian, rather than assisted suicide charges, because Kevorkian injected the drug into Youk, who had Lou Gehrig’s disease.

March 26, 1999 – Kevorkian is convicted of second-degree murder and delivery of a controlled substance. He serves eight years of a 10 to 25-year sentence.

Nov. 4, 2008 – Washington’s initiative, the Death with Dignity Act, is passed with 57.91% of voters in favor.

March 5, 2009 – The Washington Death with Dignity Act goes into effect.

Dec. 31, 2009 – A Montana Supreme Court ruling in the case Baxter v. Montana asserts that the Rights of the Terminally Ill Act protects a physician who prescribes aid from liability.

May 20, 2013 – Vermont signs the Patient Choice and Control at End of Life Act into law.

Jan. 13, 2014 – New Mexico Second Judicial District Judge Nan Nash rules in favor of an individual’s right to die in the case Morris v. Brandenberg. In appeal by the Office of the New Mexico Attorney General, the case is assigned to the New Mexico Court of Appeals/Supreme Court. The ruling remains in effect but only for Bernalillo County, according to the attorney general’s office.

Nov. 1, 2014 – Brittany Maynard, a 29-year-old with terminal brain cancer, ends her life under Oregon’s “Death with Dignity Act.” She had moved to Oregon following her January 1, 2014, prognosis in order to take advantage of the Death with Dignity law. There is no such law in her native California. She garnered a large following advocating for physician-assisted suicide laws via social media.

Oct. 5, 2015 – California Governor Jerry Brown signs into law the End of Life Option Act, which legalizes physician-assisted suicide for Californians with terminal illnesses. In a letter to members of the California State Assembly, Brown wrote that he thought about his own death while considering whether to sign the bill. “I do not know what I would do if I were dying in prolonged and excruciating pain. I am certain, however, that it would be a comfort to be able to consider the options afforded by this bill.”

March 10, 2016 – The California legislature adjourns a special session, paving the way for the End of Life Option Act to take effect on June 9.

November 8, 2016 – Colorado voters approve Proposition 106, which includes the Colorado End of Life Options Act. It takes effect on December 16, 2016.

December 19, 2016 – The District of Columbia signs the Death with Dignity Act into law. The Act goes into effect February 18, 2017.

April 5, 2018 – Hawaii’s “Our Care, Our Choice Act” is signed into law. The Act goes into effect January 1, 2019.

May 15, 2018 – California’s Riverside County Superior Court Judge Daniel Ottolia overturns the 2016 state law that allows doctors to prescribe lethal drugs to terminally ill adult patients. In his tentative oral ruling, he says it is unconstitutional because the Legislature passed it during a special session convened by Gov. Jerry Brown to address health care-related issues. The state attorney general has five days to file an emergency writ, a type of appeal, to seek a stay and keep the law in place.

May 15, 2018 – Judge Ottolia issues an oral ruling in favor of the plaintiffs and ends physician-assisted suicide in the state of California. A motion to vacate the judgment is rejected. Five days later, Ottolia issues his written opinion. California Attorney General Xavier Becerra requests an immediate stay and appeals to the state’s Court of Appeals. In June, the judgment ending physician-assisted suicide is stayed by the appellate court, making it legal in California again, pending further litigation.

Feb. 27, 2019 – The California Supreme Court affirms the stay issued by the state’s Court of Appeals, making the option of aid in dying legal for terminally-ill adults who meet certain qualifications.

April 12, 2019 – New Jersey Gov Phil Murphy signs the Aid in Dying for the Terminally Ill Act into law. It will allow adults with a prognosis of six months or less to live to get a prescription for life-ending medication. The law requires either a psychiatrist or psychologist must determine that the patient has the mental capacity to make the decision. The law goes into effect on August 1.

June 12, 2019 – Maine Gov. Janet Mills signs the Death with Dignity Act into law. The legislation says mentally competent patients over age 18 with terminal diseases that, “within reasonable medical judgment, produce death within 6 months” can request life-ending medication. It requires those patients to make two verbal and one written request for the medication with waiting periods between the requests and receiving the prescription for lethal medication.
