My daughter's first boyfriend told her, privately, "Haha, your dad is a huge stoner." I'm not sure what gave him the impression. I've never touched the stuff. (No judging, it's just not for me.)
It precipitated a big disagreement, which was a factor in their eventual break up.
Last I heard, he washed out of the Naval Academy, and recently texted her looking for a hookup, only to be rebuffed. "He was a jerk then, and who does he think he is now?"
She's awesome. 😁
