My mom caught me reeking of it one day, long story as to why I didn't successfully get the smell off.

She said she wanted to talk about it later, but dropped it. Since then it's been a subject we don't touch but I'm sure she knows about it, she's made a couple references such as:

"Don't drive under the influence"
"Mom I'm not drinking there"
"I mean under the influence of anything"

That and a few days ago I was talkin about a prank me and my friend pulled, she put some catnip she was taking to her cat in a baggie and tied it up like weed, to scare her mom. Randomly, my mom starts going ON AND ON about how she doesn't thing it's that bad or anything... not wanting to talk about it, I just say "What does that have to do with catnip?"

I'm against telling parents unless they either do it themselves or did it and don't think it's bad, so just be careful.
