I agree, but plenty of children are hospitalised or die after accidentally overdosing on medication that people leave out.

There are a lot of grandchildren that die after visiting their grandparents and taking an overdose of strong meds. Older people without children tend to forget that meds need to be locked up and don't want the inconvenience of locking meds away when they only have children around occasionally.

These are preventable deaths, they do happen, they happen way too often, but these are not reasons to make the meds / drugs illegal.
