The line my shitty parents would always give was "all the people we know who do a lot of marijuana are burn outs and don't go anywhere in life" to which my internal mental response has evolved into "CORRECTION all the people you know who are stupid enough to let your judgemental-ass know they smoke marijuana you mean".

Some of my parents best friends regularly smoked marijuana when I was growing up and neither me nor my parents knew because those adults knew how childlike and intellectually unserious my parents' judgements were around drug use.
