No; I do have a family member addicted to alcohol.
I have some addicted to pot, and friends, too. Did anyone else in your family smoke it?
A few, and as far as I know they were never addicted. Are you getting anywhere near making any kind of a point?
It’s easier for you to blithe about addiction since you know little about it first hand. That’s the point. The more obvious something is the harder it is for you to see it.
