I know that there may be people who won't fully agree with me, but just realistically and logically speaking, I do believe some safeguards should be present. Mainly a waiting period and being of the age of majority (18 in most countries).
Of course, I have stated before and will reiterate, just because there is an age requirement, it doesn't mean it should be a blanket ban/restriction on people under 18 who want to CTB, especially those who are terminally ill, or severely ill. It is a case-by-case basis and if a minor who is severely ill or even terminally ill, they should be granted the right to a peaceful, dignified exit (in my opinion), albeit there may be more checks and safeguards as well as parental/guardian input on it (because it is a minor rather than a full, legal adult).
Additionally, with waiting periods, this allows multiple chances for a person to change their mind and also not impulsively choose to CTB without giving it a second thought (in the event one changes one's mind). Also, with the waiting period, this allows the process to be documented and all the correct procedures followed (including checking for whether the person is truly choosing out of their own volition, not being pressured, not being coerced or coached into dying (since I believe without any safeguards, it is ripe for abuse and misuse), and of course having a competency test (objective one, not subjective bullshit) to ensure the person knows that they are choosing the option clearly and not under duress, under the influence of mind altering substances (e.g. should be sober when making the decision, not impaired), and having capacity.) Of course, depending on the ailment, the waiting period could be longer or shorter, but not excessively long (e.g. many years), but maybe like 6 months - 1 year for non-terminal illnesses (could be shorter/longer, depending on circumstance of course), but for terminal illnesses, it is much shorter, usually within 2-3 months (or even shorter depending on the prognosis).
Other than that, I don't believe there should be much more red tape with the option of assisted suicide for adults of legal age, of sound mind, and consenting to die.
