Medicine Cabinets Are a Primary Target
Some medications are worth a lot of money, but they are replaceable, so that is not the concern here. The real fear is that you will put something of value there and it will be found and stolen. If you hide things in your medicine cabinet, at least think outside the box.
As one former burglar on Reddit noted, this is often a hotspot for burglars who want to take your valuable items. They assume you’ve hidden jewelry there, along with other valuables like cash, which is the case sometimes. Perhaps if you do leave something of value there, put it in a tissue box or something.
