Lawmakers in Holland could soon debate legalizing assisted suicide for the elderly.
The Of Free Will campaign has gathered more than 100,000 signatures, which is enough to force a debate.
"We've been overwhelmed by the amount of reactions, especially because people took it so seriously and reactions were mostly positive," spokeswoman Marie-Jose Grotenhuis told reporters on Monday.
The group behind the campaign wants those debates to happen after national elections scheduled for June 9.
Opinion polls in Holland show significant support for euthanasia for seniors, but the Royal Dutch Medical Association and religious organizations oppose the idea.
Under Dutch law, two doctors must agree that a patient is suffering unbearably from illness with no chance of recovery, and no longer wants to live, before he or she can be given a lethal dose of sedatives.
The Netherlands has already legalized voluntary euthanasia for the terminally ill.
