Pain meds...yes.
A large enough dose intentionally to kill you...no.
So how does this work. If a patient takes two or three days worth of pain meds they will die. Following you line of thought a doctor could only give a patient a day or day and a half worth of pain meds at a time? Ya, right. You are going to make a terminally ill patient run back and forth to the pharmacy every day? Or are you counting on them to always have others there to do it for them? If they can't find others to do this then they do without their pain meds and die in agony. How about if they hoard half of their meds for 4 days? How are you going to stop that?
Sure, this works perfectly.
How about if the do-gooders get their nose out of others lives and let them make their own decisions. If they have to deal with God so be it but in the mean it is not your place to play god and make that decision.
I've always laughed about the laws against suicide. What are you really going to do with those laws? Are you going to arrest someone who successfully commits suicide?
If you manage your pain meds, you can accumulate enough to kill yourself pretty easily.
I guess you mean that when I get a little older and close to the edge someone is going to come around and take most of the powder out of my bullets? So I don’t hurt myself too much? Seems to me that a guy who is pretty beat up and about done has a right to ask for a little help that won’t result in ruining the living room couch? I’ve seen too many guys go out the hard way to entirely buy into that “pain killer” option solely.
