If a person is living with an active addict, or an addict they suspect is active, it is only good sense to lockup or hide any medications, valuables, banks cards and checks, and anything else that might be taken that would have an impact on US.
It's sad to have to do this but it's sadder to wake up one day and find your bank account emptied or your much needed medications missing.
Sleeping with my car keys was the final straw that made me wonder what I was doing with an active addict in the house.
Just my experience, hope it helps you.
