"The legislation literally forces people to kill themselves in an undignified manner," he said on his YouTube channel.
However, the logic of a "death with dignity" by suicide is flawed, according to Dr. Greg Bottaro of the CatholicPsych Institute.
"Where they're claiming the right to choose to die, based on the dignity of the person, is an error in their logic. It's because precisely of the dignity of the person that we don't have the right to choose how we're born or die. The dignity of the person is greater than what they presume it to be."
Adam ultimately took his life using an illegally imported drug mixture April 13, 2017, after checking into a motel room that morning.
"My son deserved to die with dignity, with his family and his friends beside him, in his own, comfy bed," his mother, Maggie Maier, says in her closing remarks in a YouTube video, having just read the letter he had written her before taking his life.
In that eulogy, she noted that had she and Adam's father been present, they could have been criminally prosecuted. She characterized her son as having been forced to take his own life by himself by Canada's law.
Bottaro also described the legalization of euthanasia as a "complete and utter failure of the medical system and of the government in providing the hope that people would need to actually get better."
The American Foundation for Suicide Prevention (AFSP) refused to comment for this story. Both the National Suicide Prevention Lifeline in the U.S. and the KidsHelpPhone in Canada did not respond to CNA's request for comment.
The Center for Disease Control's guidelines on media coverage of suicide warn against "(p)resenting suicide as a tool for accomplishing certain ends" or "(g)lorifying suicide or persons who complete suicide," as such coverage is "likely to contribute to suicide contagion."
"Such actions may contribute to suicide contagion by suggesting to susceptible persons that society is honoring the suicidal behavior of the deceased person, rather than mourning the person's death," the guidelines state.
A video accompanying the BBC piece contains speakers who suggest that the exclusion of mental health cases from the Canadian law stems from a stigma around psychiatric issues.

However, legalizing suicide will not serve to fight existing stigmas around mental issues, as the advocacy of Adam and his parents suggested, but will only legitimize that aversion to mental issues further, said Bottaro.
"It's taking that avoidance to the extreme," according to Bottaro. "We're just going to make these people disappear."
Additionally, the "moral stigma," as Langley described, around suicide can often save lives.
"Sometimes, it's just the desire to not want to make an immoral decision that keeps people alive, if they're suffering from a mental illness," he said, although we must also keep in mind that their pain is often so great that moral decision-making is impaired.
How can suffering be redemptive?
In Adam's case, Bottaro said, "(t)here was a total absence of understanding of anything good coming from suffering. Helping somebody process the meaning of their suffering would help move towards a different conclusion. There's really almost nothing as unbearable as suffering without meaning, or purposeless suffering."
