Your family destroyed itself using the drugs.
It could have destroyed itself with weapons or with other intoxicants.
It is the urge to destroy oneself that needs to be addressed, and as long as an item which is neutral until used gets pegged as “responsible,” that urge won’t be addressed. Satan will hide quite nicely behind that non-sentient front.
Even the bible knows about this (it is not a stupid book).
Your compassion is overwhelming. Jerk.
OF COURSE I KNOW THEY DID IT TO THEMSELVES.
