tobacco right? J/K if she dosent mention it, no worries, if she does, take your lumps. Either way, you are still going to be alive and well (if maybe a little grounded) but first offenses dont normally get punnished to severly by cool moms.

My mother found a pack of ciggarettes in my cargos years ago, and they just appeared in my room with a sticky note with a frowny face on my dresser. If she didnt flip yet i wouldent worry.

I dont know how old you are, but there are way worse things in the world to be worried about.
