The Tasmanian President of the Australian Medical Association is comparing the push to legalise euthanasia to support for capital punishment.

Consultation on a private members' bill co-sponsored by Premier Lara Giddings and Greens Leader Nick McKim ended on Friday.

The two MPs say they will now review the feedback they have received before tabling a bill to introduce assisted dying legislation later this year.

The AMA's John Davis says doctors are vehemently against the plan.

"I'm not sure that the majority of doctors, if in fact any doctors, would want to euthanase people, and that's not being taken into account," he said.

"The Premier and the leader of the Greens have been so contemptuous, they've not even consulted the profession.

"Being really blunt, this is legislation for state-sanctioned murder and the last one of those in Australia was in 1964."

Mr McKim says Dr Davis's comments are disgraceful and do not represent the views of Tasmanian doctors.

"Dr Davis has just abandoned his members who currently are performing euthanasia in hospitals," he said.

"We have doctors who are motivated by compassion and respect for human dignity who currently euthanase patients and the AMA has just come out and sold those doctors down the river."
